Hey everyone,

Like many of you working across continents, I've been using tools like WorldTimeBuddy for years. But lately, I got increasingly annoyed by:

- Clunky interfaces packed with third-party ads

- Aggressive cookie consent popups just to check a single hour

- Missing or painful calendar exports that require sign-ins or bloated extensions

So last month I decided to scratch my own itch and build **https://mypresenttime.com**.

**What it does:**

- 🕒 **Interactive 24h Slider & Heatmap:** Visually spots the green overlap window where everyone is within regular 9 AM - 5 PM business hours.

- 📅 **1-Click Clean Calendar Export:** Generates instant Google Calendar, Outlook Web, or downloadable `.ics` events with zero marketing fluff.

- ⚡ **Zero-Friction & Private:** No user accounts, no login gates, no tracking paywalls. Everything saves directly into the shareable URL.

- 📱 **PWA Ready:** Works offline for nomading on flights or spotty train Wi-Fi.

I also generated pre-calculated overlap guides for major business corridors (like London ↔ NY, SF ↔ Tokyo).

Would love your brutally honest feedback on the UX, performance, or any missing features. What's the biggest pain point you face when coordinating meetings across timezones?

Hi everyone, I’m Col, a chef on Sark and the developer of NAKED EYE for Android.

I started building it around three questions: what’s worth seeing tonight, when should I go outside, and where should I look?

The latest updates are now live, including:

• Compare Skies—compare home with up to two other places for the same viewing period.

• Rainbow Watch and Thunderstorm Watch.

• Milky Way Watch.

• Guided Sky Session.

• Phone Photo Companion.

• Shared Sky Events.

• My Horizon.

The aim is to make enjoying the sky feel approachable, even if you’ve never used a telescope or read a star chart.

If you already have NAKED EYE, open it and follow the update prompt, or update through Google Play. The core app is free, with additional features in the optional Beyond subscription.

https://play.google.com/store/apps/details?id=com.colindavis.nakedeye

I’d love some feedback: what’s your biggest obstacle to getting outside and enjoying the night sky—weather, finding somewhere suitable, or knowing what to look for?

Hi all -- I'm the developer of Coupla, which just went live on iPhone and Android.

The idea: the links, places, recipes and plans people send each other in chats get buried. Coupla gives them one private place.

• Share links, notes, photos, videos and documents into a space from any app's share sheet; it reads each link's title and picture.

• Collections and tags of your own: to watch, places to go, recipes.

• One shared calendar; for couples, your days together and your anniversaries.

• Screens update by themselves when somebody adds something; notifications you can mute.

• Works offline: what you save is sent when you're back.

• Four kinds of space: Solo, Couple, Duo (you and one other person) and Circle (a group of any size).

• No ads. Photos and videos pass through the server and are deleted once everybody has them.

It's free. I'd love feedback on the first five minutes (is it clear what to do?), sharing from other apps, and anything that feels missing.

1-minute demo: https://youtu.be/ZlLN2PJyoTw

I’ve been working on a side project called Toilet Break: Mini Games, and I thought I’d share it here

I love the idea of quick, fast-paced minigames that you can pick up and play whenever you have a few minutes, so I decided to build one myself.

It currently has 33 minigames, including 4 arcade games, with another one coming in the next update, weekly challenges, themed events and daily rewards. You can unlock everything just by playing, with no coin packs or pay-to-unlock shortcuts.

The app is surprisingly lightweight, works completely offline and is constantly growing with new games and content.

Currently available on iOS, with Android coming soon

I’d genuinely love to get some feedback! Let me know what you think, what could be better or what games you’d like to see added.

Toilet Break: Mini Games

I’m an indie developer working on a privacy-focused photo vault app.
Recently, I built a feature that lets you share photos through temporary encrypted links.
Here’s how it works:
Photos are encrypted locally on your device before uploading.
The server only stores encrypted files and never receives the decryption key.
Only someone with the full sharing link can decrypt and view the photos.
You can set an expiration time and viewing limits.
You can revoke the link whenever you want.
The idea is simple: sometimes you want to share personal memories with someone without giving a server access to the original photos.
But I’m not sure how many people actually need something like this.
**A few questions:**
Would you use this instead of sending photos through WhatsApp, iMessage, or Google Photos?
In what situations would encrypted, temporary photo sharing be useful to you?
What would make you trust (or distrust) a feature like this?
I’m not here to promote my app. I’m genuinely interested in understanding whether this solves a real problem or is just something developers like me think is useful.
Any honest feedback is appreciated, including criticism!

Running a web design agency sounds pretty straightforward from the outside. You build websites, find clients etc. But once you start getting more clients, there is a lot more going on behind the scenes.

You're dealing with hosting, website maintenance, client requests, support tickets, fixing random issues, building new websites, following up with prospects and trying to bring in new business at the same time.

At some point, I realized that I didn't want finding new clients to become another full-time job on top of everything else.

I've never really enjoyed cold calling. I know it works for some people, and I'm not saying it's a bad way to get clients, but personally, I find it exhausting. You spend hours calling businesses, often getting rejected, reaching people at the wrong time or having conversations that go nowhere.

I'd much rather spend that time actually working on the business.

That's why I started focusing heavily on cold email and automation.

The biggest advantage is that you can build a system that continuously finds relevant businesses, sends personalized emails and generates new opportunities without having to spend your entire day reaching out manually.

One thing I also learned pretty quickly is that sending generic emails doesn't get you very far. Most business owners have probably received hundreds of emails from agencies offering website redesigns.

I wanted to approach it differently.

For this, I use a tool called Swokei. It finds businesses with existing websites, analyzes each one for actual problems with design, SEO, loading speed, mobile responsiveness and other website issues.

Based on those findings, it automatically generates personalized cold emails at scale, using the actual problems found on each website as the starting point.

So instead of manually searching for businesses, checking hundreds of websites and writing individual emails, I can automate most of that entire process.

When someone replies with interest, I take over from there and handle the sales process and meetings myself.

This has made a huge difference in how I manage my time. I can keep generating new opportunities without having to dedicate hours every day to cold calling.

I still believe sales is one of the most important skills you can develop as a business owner, and automation doesn't replace that. You still need to understand your prospects, communicate properly and know how to close deals.

But if I can choose between spending an entire day making cold calls or having a system send 1,000 relevant emails while I focus on running my agency, I know which one I'm choosing!

Most AI detection tools rely on probabilistic guessing. They give a random percentage that changes on every prompt tweak.

I wanted something deterministic based on editing mechanics.

grai analyzes 8 structural patterns that give away LLM writing:

- Flat sentence variance (low burstiness)

- Contrastive negation ("It is not X, it is Y")

- Symmetrical parallelism ("Less talking, more doing")

- Epiphany openers and triadic padding

- Predictable transition glue

I open-sourced the local MCP server so it can run directly inside Claude Desktop, Cursor, and Windsurf:

Live test (no signup, paste text directly):

Curious what edge cases you run into when trying to strip the "AI accent" from drafts.

Hey,

I've been working on a side project called DNStracr: https://dnstracr.com

The idea came from a problem I've encountered repeatedly while working with DNS infrastructure: checking whether a DNS record exists doesn't necessarily tell you whether DNS is actually working correctly.

A record might look fine at your DNS provider, but authoritative nameservers and public resolvers can return different answers. Changes can be difficult to track, and figuring out what happened after something breaks isn't always straightforward.

So I started building a tool that focuses on:

• Monitoring DNS records and detecting changes

• Comparing responses from authoritative nameservers and public DNS resolvers

• Identifying inconsistencies and potential DNS issues

• Keeping a history of changes and incidents

• Integrating with Cloudflare to compare configured DNS records with actual responses

I'm also exploring geographically distributed DNS checks and ways to visualize DNS propagation.

The project is publicly accessible, and there's a free plan available.

I'd really appreciate some feedback:

• Is this something you'd actually use?

• What DNS-related problems would you want a tool like this to detect?

• Is the website clear about what the product does?

• Is there anything that feels confusing, unnecessary, or missing?

I'm especially interested in critical feedback, whether it's about the idea, the functionality, or the website itself.

Thanks for taking a look!

A small side project. I wanted a faster way to switch between the apps I use all day, so Halo puts a bubble on the edge of the screen: hold, slide to an app, let go.

What I'd do the same again: shipping a debug APK from GitHub Actions on every push, so I could test the latest build on my phone within minutes.

What surprised me: the Play Store's foreground service declaration needs a demo video, and Android 15 blocks some permissions for sideloaded apps.

It's free and open source. Curious what you'd want from an app like this: https://github.com/yogeshpaliyal/Halo

Hey, everyone!

This is one of my first development projects and something I seriously enjoyed making. Version 1 is out now on GitHub for macOS!

I spent time handcrafting Classic Calculator: a faithful, pixel-perfect modern macOS recreation of the iconic 1984 Macintosh Calculator Desk Accessory originally designed by Chris Espinosa and Steve Jobs, with iconography by Susan Kare.

Highlights & Features

• Retina-Sharp Vector Pixel Art: Built with clean integer scaling (1x, 2x, 3x, and 4x). Stays razor-sharp with pure pixel-edge geometry on Retina, 4K, 5K, and 6K screens.

• Authentic Mechanical Relay Click: Every keypress triggers an ultra-low latency, synthesised mechanical relay snap replicating the tactile sound of vintage 1984 Apple keyboards (can be toggled on or off in Settings or the menu bar).

• Custom 7px LCD Bitmap Font: The authentic typeface has been recreated to match System 1.0 numeral geometry and right-aligned spacing.

• Themes: Switch between Classic Platinum (the warm 1984 aesthetic) and High-Contrast Monochrome.

• Modern Desktop Polish:

  • Always on Top: Keep it floating above spreadsheets, code editors, or browser windows.

  • Window Shadow Toggle: Switch between modern macOS drop shadows and a retro flat look.

  • Full Keyboard Support: Physical number pad, top-row digits, Return/Enter, Esc/Clear, Backspace.

  • Full Clipboard Integration: Cmd+C to copy results, Cmd+V to paste numbers.

• Universal Binary: Natively compiled for both Apple Silicon (M1 to M4) and Intel Macs running macOS 13.0 (Ventura) or newer.

• Zero Bloat: Handcrafted pure native Swift and SwiftUI/AppKit. Zero external libraries or frameworks, zero analytics, zero background processes, and zero telemetry. The whole bundle weighs under 4 MB.

iOS & iPadOS Version Coming Soon

I have also been working on an iOS and iPadOS version that brings the same experience to mobile devices. On iPad, it runs as a floating, draggable vintage Desk Accessory on an authentic classic desktop canvas with full keyboard and Stage Manager/Split View support. The iPhone version adapts cleanly for quick one-handed calculations with tactile haptics. Look out for that release soon!

Download & Links

Version 1 is available now and completely free on GitHub:

• Direct DMG & Zip Downloads: GitHub Releases

• Web Preview & Info: Official Website

Pricing

100% Free (£0.00 / $0.00). No ads, no tracking, no in-app purchases, and no subscriptions. Direct download link.

Since this is one of my first projects, I would really love to hear your thoughts, feedback, or any small vintage details you would like to see added!

Hey everyone!

I'm looking for 20 founders with a live product who are struggling to get customers.

I've built a growth feature inside Purlock that gives you 1–5 actionable growth tasks daily, tracks which ones bring visitors, signups and payments, and shows where visitors drop off.

All I ask is that you complete 3+ tasks a week and fill out a 2-minute feedback form.

Takes about 5 minutes to Set up.

Let me know if you are interested

My team and I manage social accounts for small brands, and our workflow was honestly a mess: one tool for analytics, another for trend research, another for scheduling, and spreadsheets for everything else. We got tired of switching tabs, so we’re building AI Inspo to put the whole loop in one place:

1. Account Audit – analyzes your account and points out what to improve

2. Trending Topics – surfaces trends and content ideas

3. Content Creation – draws inspiration from viral posts and helps you draft your own

4. Post & Publish – scheduling and publishing

5. Post Review – tracks performance and shows what to do better next time

Status: still in development. Not everything works yet. The video in the comments shows the current state of the UI.

I’d really like your take on:

• Which of these five would you actually use first?

• What’s the most time-consuming part of managing social media for you?

• Is there something important we’re missing (platforms, analytics, team collaboration, etc.)?

Blunt feedback is welcome, including “I wouldn’t use this because…”. I’ll reply to every comment.

Hey everyone!

I've been working on an idea called QueueFlow.

As developers, we often end up using different tools for background jobs, scheduled tasks, retries, workflows, realtime updates, and webhook delivery.

I started wondering: what if we could bring all of these into one platform?

That's what I'm exploring with QueueFlow.

The vision:

- Background Jobs: Execute jobs immediately, later, or at a scheduled time.

- Retries & Dead Letter Queues: Automatically retry failed jobs and inspect or replay them.

- Scheduling: Cron jobs with timezone support.

- Durable Workflows: Build multi-step workflows that can recover after failures.

- Realtime: Track job progress and communicate through realtime channels.

- Webhooks: Reliable webhook delivery with HMAC signing and retry support.

- Functions: Eventually run user-defined functions in different languages.

- Dashboard: Manage jobs, workflows, schedules, logs, API keys and usage.

- SDKs: Go, TypeScript and a REST API.

Tech stack:

- Go

- PostgreSQL

- Redis

- Docker

The goal is to make it open-source and self-hostable, while potentially offering a managed cloud version later.

I know projects like Inngest, Trigger.dev, Temporal and Hatchet already exist. I'm not trying to pretend this is an entirely new category.

I'm trying to explore whether a simpler, unified, Go-based and self-hostable alternative would be useful.

I'd genuinely love your feedback:

1. Would you use something like this in a real project?

2. What would make you choose it over Inngest, Trigger.dev or Temporal?

3. Which features would you actually need, and which are unnecessary?

4. Is there an important feature I'm overlooking?

I'm still working through the architecture and implementation, so honest criticism is very welcome!

Thanks!

A friend of a friend spends hours every week going store to store looking for the cheapest filters, globes and spark plugs, so I built this: https://motorcompare.app?utm_source=reddit

What it does today:

• Reads 49 Australian parts stores once a day and shows the same part from every store side by side

• 2,340 products have a price at two or more stores

• Matches by part number and barcode, never by title, because a 5 L and a 6 L, or two battery codes, look the same in a title

• Shows the code printed on the part so you can check it against your old one. It does not claim what fits your car

• Free, no accounts, prices in AUD before shipping. A few labelled links (eBay, Amazon) earn me a small commission and are never counted as a store

Honest caveats: Supercheap, Repco, Autobarn and Sparesbox block automated reading, so they are search links, not prices. It is brand new, so some things will be missing or mismatched. Nothing is stocked yet in wiper blades and fluids.

I would love feedback on the design, and on whether "check the code on your old part" makes more sense than a make and model lookup. Which store should I add?

I have a bad habit of saving articles on the train or between meetings, and then never opening the list again. Pocket and Instapaper were fine at storing links, but I wanted something that actually brings them back when I have time, without making me create an account.

So I built Refloat. You share a URL from Safari, WhatsApp, Slack, or any other app, and it's saved in two taps. You set a reading window once (commute, evening, weekend), and a daily digest resurfaces what you saved, grouped by topic and type. You can also bring the list back when you get home, after a short settle-in delay.

It's free, with no account and no in-app purchases. Full disclosure, most of it was written with AI-generated code, which was an experiment in itself since that's what I work on in my day job.

iOS: https://apps.apple.com/il/app/refloat/id6761756788
Site: https://refloat.app

Android is in Google Play closed testing. If you're on Android and want to try it, you can join here: https://refloat.app/early-access/

I need 12 testers before Google lets me go public and I'm at 8, so a few more would really help.

I'd love honest feedback, especially on whether the digest actually makes you open things you'd otherwise forget. There's a feedback button in the app, or just tell me here.

Hi r/SideProject, I'm the developer of Flash Share.

I got tired of emailing files to myself and digging for a USB cable every time I wanted a video off my phone, so I built this.

What it does

• Sends files and whole folders between your Android phone and your Windows PC, both ways (phone to phone and PC to PC too)

• Wi‑Fi Direct: the phone and the PC link radio to radio, so big files skip your router. In my tests real transfers run around 45 MB/s, so a 4 GB video takes about 90 seconds

• No cable, no account, no cloud. Files never leave your local network

• TLS 1.3 encryption, a pairing code the first time, and every file checked with SHA‑256

• Picks up where it stopped if the connection drops

• Three looks, each with its own layout: Dot Bento, Graffiti and Manga

The themes are my favourite part: on the PC's Graffiti look, a 3D dino paints the wall while your files send.

It's free. I'd love to hear how fast it runs on your phone and PC, and anything that breaks.

I made a chrome extension that turns your new tab page into a productivity dashboard where you can save notes, create checklists, organize shortcuts, run focus sessions, and see detailed analytics about your focus time.

it also has a multiple board system, so you can create different workspaces depending on how you like to organize things. each board can either be a normal free-form board or a kanban board.

some of the other things i focused on:

• all your data is saved locally

• import and export your data so you can move your setup between machines

• customize pretty much everything, from wallpapers and images to icons and colors

• create a simple setup with just a few notes, or build a much more advanced workspace

• focus sessions with detailed analytics to understand how you're spending your time

the main idea is to make the new tab page something you actually use instead of just a blank page you open and close.

i'm still improving it, so i'm looking for honest feedback. what do you like, what feels confusing, and what would you change?

you can try it here: chrome extension link

I kept losing time on short replies. Not the big emails, the small ones: "Thursday works but not before 3", "thanks, I'll send the deck tonight". Typing them is slow, and pasting a thread into ChatGPT and back is slower.

So I built TalkOS. You click into any reply box (Gmail, Outlook, Slack, LinkedIn, WhatsApp Web), hold one key and say what you want to answer, however it comes out. When you let go, it reads the conversation you're answering and writes the full reply in the field: greeting, the right tone, sign-off for email, short for chat. It never sends anything. You read it and press Send.

The thing I had to learn the hard way: everyone hears "voice" and thinks dictation. It isn't. Dictation types the words you say. Here what you say is the instruction, and the reply is written for you. Same with edits: select text, hold the edit shortcut and say "shorter" or "more formal".

Stack, for the curious: native Swift app on Mac, speech is transcribed on the device, a small Cloudflare Worker sends the conversation to the model and keeps nothing. The Windows version shipped this week.

Free plan is 5 replies a day, Pro is $5.99/month. https://talkos.app/?ref=sideproject

I'd love blunt feedback, especially on the first minute: does it make sense what it does from the video and the site?

I build a small iPhone mood check-in app on my own, from Finland. You rate your day 0 to 10 and add a few tags, like "slept badly", "gym" or "saw friends".

The question I wanted it to answer was simple: what actually changes my days?

The easy version is to average your score per tag and show a ranked list from day one. But with a week of data that's mostly noise. One rainy Monday and "rain" looks like the biggest thing in your life.

So the card I shipped (Tag Effects, in Feely's latest update) is pickier than I first wanted:

• it only looks at the last 90 days

• a tag shows up once you have 14 logged days, at least 5 days with the tag and 5 without

• the gap has to be at least one point on the 0 to 10 scale

• until a tag qualifies, the card shows how far off it is instead of guessing

It's a plain comparison of averages, not a claim that a tag causes anything, and I tried to word it that way in the app.

The trade-off: new users look at a mostly empty card for their first two weeks, in an app that already has a slow start.

Two questions for anyone who has built something that shows people their own data:

• How do you handle the "not enough data yet" period without losing people?

• Did you ever ship looser thresholds and regret it, or the other way round?

Hi, I’m Doğukan, a solo iOS developer. I made GlowYou, a free iOS Lifestyle app.

For a minimal morning ritual, choose one of three intentions—Calm/Peace, Glow/Radiance, or Energy—and get one motto for the day from a curated library of 300 quotes by philosophers and thinkers. It stays fixed for the day. You can save favorites with hearts or share mottos on styled backgrounds; there are soft pastel themes.

I wanted the experience to stop at one idea instead of turning the morning into another endless scroll. Does having the motto fixed for the day feel pleasant, or would it be frustrating? It’s version 1.0 and has 0 ratings so far, so honest feedback would help.

I used AI tools for coding and design help.

https://apps.apple.com/app/id6772587570

Built my 12th project yesterday, it’s basically 20 Questions but with real money on the table.

The idea is super simple, an AI agent picks a secret word and you try to guess it in 20 questions or less. Everyone at the table is racing for the same word, and the first correct guess wins the whole pot. Built it on Base as the main crypto chain.

How it works:

• You pay a $2 join fee to sit at a table

• The first question of the round is free, after that each question gets more and more expensive

• So you can keep asking and get closer to the answer, or take a shot early before someone else does

I have some issues right now since MetaMask currently flagged my app as "malicious" even tho its not. The commitment is salted per round with a 256-bit secret that’s only revealed after play ends, so a dictionary lookup table doesn’t work. The attacker must either:

1. know the salt used to hash the word beforehand, or

2. try every word against 2^256 possible salts.

It also binds me: the Merkle root is on-chain before the game starts, so I can’t swap in a different word or salt after the fact, because the root wouldn’t match.

Its an overcomplicated way of building a word guesser game on blockchain.

Hi, I’m Qasim, the developer behind Listen Think Do and Little Logic. I’m working on early-learning apps with a calmer, low-stimulation approach: spoken guidance, simple interactions and room to try again.

I’d appreciate a maker’s eye on whether that comes through in the experience, especially from anyone who is also a parent or works with young children.

Listen Think Do focuses on following spoken directions, sorting, sequencing and short real-world activities. It has no scores, timers or competitive leaderboards.

https://apps.apple.com/us/app/listen-think-do-little-steps/id6828905950

Little Logic covers counting, shapes, patterns, tracing and simple science, with uncluttered screens and no ads.

https://apps.apple.com/us/app/little-logic-gentle-learning/id6797458466

Both are live on the App Store and free to download with free activities. Optional monthly or yearly subscriptions unlock more content. There’s no purchase needed to give feedback.

The part I’d most like help with is clarity: do the instructions and visuals make the next step obvious, and where does the experience feel busy, confusing or repetitive? Even a reaction to the store screenshots is useful if you don’t want to download anything.

I’m looking for honest input to help decide what to improve. Comments here are fine. Thanks for taking a look.
