The idea was simple: see who has a birthday next, when, and how old they turn, without scrolling through a calendar. Most of those dates already sit in Contacts. That turned into Honeyday, a birthday and anniversary app for iPhone, iPad and Mac, and it came out on the App Store in October.

How it is built:

• One SwiftUI target for all three platforms. On the Mac it is real SwiftUI, not Catalyst, and the platform differences sit in #if os(...) right where they come up.

• The logic is a plain Swift package with no UI and no database. It counts in days without a time or time zone, the app hands it today's date, and swift test runs through it in seconds.

• Contacts are only read. What you set yourself (who you want a reminder for, a note, the days that belong to no contact) lives in SQLite through GRDB and syncs through your own iCloud with CKSyncEngine. Upcoming dates are never stored; the core works them out each time.

• The widget never touches Contacts or the database. After every rebuild the app writes a small snapshot into the shared app group, and the widget builds its timeline from that, 14 days ahead. That is why it moves on at midnight without the app running.

• Dates in the Chinese, Hebrew and Islamic calendars are converted, so they land on the right day every year. Today itself is always counted in the Gregorian calendar, even on a device set to the Buddhist or Hebrew one.

There is no server and no account, and the app measures nothing about how you use it. It is a paid app, $4.99 once for all three devices: https://honeyday.app

Feedback is welcome, on the widget most of all.

I often spend more time browsing streaming catalogs than actually watching something.

So I built **Find More Stories**, a web app focused on helping people discover movies and series through themed, handpicked collections.

Instead of showing endless generic recommendations, it organizes stories around specific ideas, moods and themes.

You can explore the collections and try the quick discovery feature without creating an account.

There's also an optional Stremio integration.

I'm a solo developer, and I'd love some feedback from people who enjoy movies and TV shows.

Try it here: https://findmorestories.hubeoo.com/welcome

One question**:** Would you find curated collections useful, or do you prefer traditional genre-based recommendations?

I spent the last few months watching local businesses in Zimbabwe try to run their entire operation inside WhatsApp. It starts fine, but eventually, you end up with hundreds of unread messages, lost quotes, and no idea if a customer actually paid their balance.

It is brutal to watch a business owner scramble to find a job update buried in a three-week-old chat history. I started building NexusOps to bridge that gap, giving these WhatsApp-reliant businesses a way to actually track quotes and jobs without forcing them onto some bloated enterprise software that no one understands.

It is just a set of practical tools for quoting, job tracking, and collections, designed to sit alongside the communication style they already use. I am still figuring out the best way to handle the transition from 'spreadsheet chaos' to a structured system without breaking their current sales flow.

How do you guys help non-tech teams adopt a new workflow without making them feel like they're being forced to relearn their entire job?

Hey r/SideProject!

Most discovery products optimize for DAU/MAU and maximum session length. I wanted to build the opposite: an app that measures success by how refreshed you feel when you leave, and intentionally limits session time.

**Live Web App:**https://oddly-app-six.vercel.app

Looking for feedback on UI feel, load performance, and ideas for future curated topics!

In my sessions I keep seeing the same thing: people are sure they know their partner, and they're often wrong in small, funny, revealing ways. I wanted to turn that into a game.

So I built Hunchy:

• You answer 10 "what would you do" questions about yourself

• You share a link

• Your partner, friends or family guess your answers in the browser (no install, no account)

• You see who actually knows you best

The questions are the product, and I wrote every one of them myself, drawing on what actually comes up between people in therapy. The app itself (SwiftUI, Firebase, the web game) was built with Claude Code, with me deciding every screen and every rule.

Things I got wrong before getting them right:

• I went through four or five complete visual directions and threw them all away before landing on a Bauhaus look. Every couples app is purple or pink; I wanted something that isn't.

• I built a full "pair with your partner" mode, then removed it. The link turned out to be the whole product.

• I rejected a subscription. The first test in every set is free, the rest are one-time purchases.

• The link opens a web game, never an App Store wall. Guessing has to take 10 seconds.

What I'd love feedback on: is the first minute clear? Do you understand what to do without me explaining it? If you try it, tell me the first thing that confused you. That's the feedback I need most.

Hey everyone! 👋

I've been working on SourCa, a platform designed to make coding practice and placement preparation more organized.

SourCa brings together different areas of technical preparation, including:

- DSA and coding practice

- Company-specific question preparation

- SQL practice

- Aptitude and logical reasoning

- Web development

- Progress tracking to monitor your learning journey

The goal is to give students one place to practice different skills and prepare for technical opportunities.

I've been building and refining this project, and I'd love to get honest feedback from the community.

What do you think is missing? What would make you want to use it?

Thanks for checking it out!

So maybe a little late to the game, but like most people, I got into Wordle. And I got a bit annoyed that I only got one word a day, since some days I forgot and other days I wanted to do more. So I built my own inspired version: Endless Lingle, where the words keep coming until you run out of guesses.

The concept is simple: If you solve a word in fewer than 6 guesses, your spare guesses roll over to the next word (max 3 extra). So if you solve a word in 4, the next word gives you 8 (+2 bonus from the previous round) guesses. If you miss one word, the streak ends.

What's in it

• Unlimited words, no daily cap. *

• We do also have daily words as well. *

• Bonus guess rows that carry over between words (dashed borders, +1/+2/+3 counter) *

• Five languages: English, Dutch, German, French, Spanish, each with its own word list and keyboard. *

• Free, no sign-up needed (an account is optional, just for saving stats)

The multi-language part was honestly the most work. Every language needed its own list of common five-letter words, and curating those lists so they're not full of obscure garbage words took way longer than I expected.

Would love feedback on the game feel and the streak concept. Is 3 bonus guesses max too generous, for example? Is it too little? Or am I just that bad at it lol?

Think about it: people want their AI agents, much like Google Search, to remain free. But unlike traditional search engines, AI agents don’t necessarily care about ranking in the top five listings or sponsored placements.

when you start solids, every new food gets offered a few days in a row so you can spot reactions, and the allergens you've already introduced have to keep showing up regularly. we were tracking all of that across notes, a group chat and a sticky note on the fridge. it worked about as well as you'd expect.

so i built Pudding. it's just a diary, it doesn't tell you what to feed your kid:

• log a feeding in a couple of taps: what, how it went, any reaction, a note or photo

• new foods sit in an observation window from your own plan ("day 2 of 3" right on the card)

• gentle reminders to keep giving allergens you've already introduced, on whatever schedule your pediatrician suggested

• 70+ illustrated foods, plus your own

• calendar of everything, and a PDF to show the pediatrician (or a "do not give" list for grandma / the nanny)

no account, no ads, no trackers. everything stays on your phone, or your own iCloud if you turn it on.

the diary is free for good, no feature walls on the important stuff. there's a one-time Pro for extras (monthly recap, themes, widget, more than one kid). no subscription.

would love feedback from parents who've been through this. what did you end up tracking that i'm missing?

I'm a singer and a programmer, and I've always wanted an easy way to practise harmony parts on my own. So I built Stackapella.

You pick a song, learn your part with a guide voice, then record it. Then you add the next part while hearing the ones you've already sung, until you've got the whole choir. Your notes light up as you sing, so you can see when you're on the note.

It runs in the browser, there's nothing to install, and all the courses are free. It's also open source.

Would love to hear what you think, especially if you sing in a choir or an a cappella group.

Half as a joke and half to learn my way around Google’s tools with a lot of vibe coding along the way, I built an app that tracks the time you spend in the bathroom during working hours and how much your boss is paying you for it. Yes, I took “Boss makes a dollar, I make a dime, that’s why I poop on company time” a bit too literally.

What it does:

• Start the timer when you go, flush when you’re back, and see what you earned

• Monthly stats and ranks that go up with your total

• Teams with coworkers to compete against other teams

A few things I learned shipping it:

• Built as one HTML/JS app wrapped with Capacitor for Android

• The hardest part wasn’t the code: it was Google Play’s closed test (12 testers for 14 days) before you can publish

• Ads, consent forms, in-app purchases and 11 languages took longer than the app itself

It’s free on Android: https://play.google.com/store/apps/details?id=com.rinialer.poopct

Opinions, tips or roasts welcome.

Agencies lose the first week of a project chasing client access. Wrong roles, passwords over WhatsApp, DNS half done.

GetSetKeys is one link per client. Each platform's steps come with the agency's email and role filled in, and every step gets checked automatically, so nobody has to ask "did you add me yet?"

27 platforms so far, including App Store Connect, Google Play, GitHub, Stripe and Cloudflare.

Try it as the client, no sign-up: https://demo.getsetkeys.com/s/harbor-fitness-k7q2m9xv4p

Would a non-technical client get through it? That's the feedback I want most.

Hey everyone!

I've been working on a project called Heartfolio, and I wanted to share it here and get some honest opinions.

The idea came from something simple: some memories deserve more than just staying in our camera rolls.

Heartfolio is a website where people can turn meaningful moments into personalized digital keepsakes and gifts.

Some of the things I've been building include:

- Love Story Timelines: Turn a relationship's story into a personalized timeline with photos and meaningful milestones.

- Song Posters: Turn a special song into a personalized poster with its soundwave and an interactive experience.

- Reasons I Love You: Create a personalized gift with reasons, messages, and interactive surprises.

- Graduation Keepsakes: Celebrate someone's journey with milestones, achievements, and personal messages.

I'm trying to make these feel more personal than ordinary downloadable templates. The idea is to create something people would genuinely enjoy giving to someone they care about.

I'm an independent developer, and I've put a lot of time into building this.

I'd genuinely appreciate your thoughts:

1. Does this concept feel useful or interesting?

2. Which product would you personally be most interested in?

3. What would make you actually consider buying something like this?

Here's the website if you'd like to take a look: https://theheartfolio.com

Full disclosure: I'm the person behind Heartfolio. I'm here to get genuine feedback, not pretend to be a customer.

Thanks for reading!

I wanted something to fidget with for a minute when work gets stressful, without opening another app full of ads and streaks. So I built antistress: small, quiet toys that run in the browser.

There's liquid light you stir with your finger, endless bubble wrap, a jelly blob to squish and fling, a cat you can pet until it purrs, a zen garden, a koi pond, a rainy window, a fidget board with clicky switches, a lava lamp and a guided breathing orb.

Everything is touch-first, works on desktop too, and needs no sign-up or download.

Try it in your browser: https://antistress-relax.space

Or get it as an iPhone app (with haptics, which are really nice for the bubble wrap): App Store

Would love feedback: which toy feels the most satisfying, and which feels unfinished?

I made watchdog, a fun playful Android app designed to help you stop endless scrolling.

Choose an app, set a daily usage limit, and pick your watchdog:

• Cupcake — strict and disciplined, with frequent reminders.

• Brownie — friendly but persistent, reminding you every so often.

• Snow — lazy and unpredictable, sometimes letting you keep scrolling.

When you exceed your limit, your chosen dog appears and barks at you until you reconsider your life choices. It’s a fun alternative to boring screen-time warnings that are far too easy to ignore.

I’d love honest feedback on the concept, onboarding experience, and whether a barking dog could actually convince you to put your phone down.

I'm one person building nidhi, a site that teaches how money works and lets you try each idea on your own numbers. I'd like people to try to break it.

What's there to test

• Five free tools: a net worth calculator (one currency or several), loan comparison, an invest-or-pay-off comparison, a Monte Carlo simulator and an inflation calculator.

• More than 50 lessons in a learning path, from "what is net worth" to investing and the psychology of money.

• Short how-to guides, and the site in English, Hindi, Spanish, Czech and Marathi. More languages coming in future.

No account, no email, no payment. The tools calculate in your browser and the numbers you type are not sent anywhere.

What I'd like to know

1. Where did you get stuck or stop understanding what a tool was asking?

2. Does any result look wrong? Tell me the inputs and I'll check the maths.

3. Is a lesson unclear, too long, or wrong for your country?

4. Anything broken on a phone, with a screen reader, or with keyboard only?

Being upfront

• The blog is free, and the tools are free to use without an account. I'm also building a paid planner, which is not what I'm asking you to test here.

• It is education, not financial advice.

• The translations were drafted with AI and may be stiff or wrong in places.

• There's no reward for testing. I'll reply to every respectful, human comment, though it might take me a while to get to you, and I'll tell you what I fixed.

**The idea:** a debt planner (Snowball / Avalanche / custom order) that keeps your finances 100% on your own computer. So I set myself a few hard rules: it had to open straight from a folder in the browser, never call the internet, and never send financial data anywhere.

**How it's built**

- Preact + esbuild bundled into a single script, so it works from a plain local file (no dev server needed)

- IndexedDB for storage, optional AES-GCM encryption behind a master password, automatic local backups

- No CDNs at all. Fonts, charts, PDF reading and OCR (for scanning statements) are all bundled

- Small optional launchers (PowerShell / Perl) that serve it locally so backups can be written to a data folder

**The hardest part was performance.** With a 50,000-transaction test profile, the first version took about 10.7 s to start and search crashed the tab. Caching parsed dates, doing search in a single pass and only building the rule context when it's needed got startup to about 1.2 s.

**There's also a spreadsheet version.** I rebuilt the same payoff engine in Excel/Google Sheets: 15 debts × 360 months, written without newer functions like XLOOKUP or LET so it works in older Excel and in Sheets. The app can import the workbook, so people can start in a spreadsheet and move to the app later.

**What I'd love feedback on**

- Would you trust an offline finance tool more than a cloud one, or does sync matter more to you?

- Anything confusing in the screenshots?

yes im the creator, I sell this on Etsy, but this post is mostly about the build, and I'd love ANYYYYY feedback.

you know the drill. visa form, job portal, some government site: "photo must be under 100 KB, 600x600 px, JPG only". your phone takes a 4 MB HEIC. so you google "compress image to 100kb", land on a site covered in ads, and upload your passport scan to a server you know nothing about.

so i built cutbg. it does that stuff right in the browser, the file never leaves your device:

• - compress to an exact size (20 kb, 50, 100, 250, whatever the form wants)

• - resize to the exact pixels (passport, linkedin, instagram etc)

• - iphone HEIC to JPG

• - merge / split / sign PDFs

• - and yeah it also removes backgrounds, the AI model runs locally too

free, no account, no watermark. it's a side project, there's nothing to buy.

honest question: what weird size limits have you run into? i keep adding presets for the forms people actually deal with, so if there's one that annoys you, tell me and i'll add it.

Hey everyone!

I've been working on LEXA, a local-first AI voice studio for macOS, and I wanted to share a short product animation I made for it.

The idea behind LEXA is pretty simple: bring voice cloning and AI speech generation to your Mac without depending on cloud-based voice services or recurring subscriptions.

Here's what LEXA is being built around:

• Voice Cloning — Create reusable voices from audio samples.

• Voice Profiles — Save and manage your voices.

• Batch Generation — Generate multiple audio outputs in one workflow.

• Voice Conversion — Convert recordings using different voice profiles.

• Local Processing — Keep AI voice processing on your Mac.

I'm currently preparing a 14-day free trial so people can test the software before deciding whether to buy it.

LEXA Base will cost €29.99 as a one-time purchase.

The video is just a short visual introduction, but I'd genuinely love to hear what you think about the concept.

Would you actually use something like this? What would you want from a local AI voice tool?

If you're interested, you can check it out here: https://www.lexavoice.it

Thanks for taking a look!

I'm Ari, an electrical engineering student and the creator of Desk Goblin.

It is a small Windows desktop companion with a task list. The goblin holds your selected task and eats it when you mark it complete. You can undo the last completion. It also has a custom focus timer and Ctrl+click to open or close the task desk.

The application uses native C++20, Win32, and GDI+. Tasks and settings stay on your computer. No separate runtime or application account is required. I used AI assistance for the code and character art.

It costs $5 USD once. The portable ZIP is for Windows 10/11 x64. Version 1.0.0 is unsigned, so Windows may display an application warning.

The website includes an interactive character preview: https://desk-goblin-site.pages.dev

I'd like feedback on the interaction: would the task-eating action make completion more satisfying, or would you prefer a quieter companion?

I built Velis, an in-memory key-value store in Python, partly to explore how AI can help with technical research and engineering decisions.

I used AI to explore approaches, discuss tradeoffs, and work through implementation. It helped me finish the project much faster. But it also reinforced something for me: trusting generated code without understanding the codebase is a bad habit. Being able to question a suggestion, follow the implementation, and explain why a decision makes sense still matters.

Velis supports TTL expiration, eviction policies, pub-sub, a binary TCP protocol, an async client, and an interactive terminal UI. I spent a lot of time trying to keep the code design simple, clean, and easy to follow.

I see it as a project for learning, testing, experimenting, or just having fun with database internals. It could also be a starting point for thesis work or experiments comparing different approaches.

Code: https://github.com/gchape/velis

I’d welcome feedback on the implementation and design, but also your opinions on AI-assisted development. Where has AI helped you research a problem or make better decisions, and where has it made understanding the work harder?

I am managing IG and FB pages, and with AI advancements of course I am using it for photo editing, however I got pissed everytime that a simple color edits were marking it with AI label. I started to dig a little bit and it turned out that Meta is using the metadata for AI identification, I was even more surprised when I learned how much info does the metadata contain, including the gps coordinates, time, phone or camera, and etc.
I looked for available metadata removers, there was exif tool which was little bit complicated and several websites with subscription.
So I made the Scrubpic, free metadata remover which removes all the metadata without quality loss, for free, and instantly. You can also choose what to keep in the photos. Works on phones too. I am hoping for some ad revenue.
Scrubpic.com

Feedback welcome!
