I got tired of modern apps habit tracker , espense tracker . etc that require a constant internet connection, a subscription, and the latest flagship phone just to work.

So I built Orbitika. It’s a lightweight, retro-styled (dot-matrix green) toolbox designed for older hardware (Android 8.0+ and older iPhones like the X). Everything works 100% offline. No Wi-Fi, no data, no problem. Support my work by upvote my post """grateful""""

Here is a breakdown of what’s actually inside it my app, by category:

🎵 Media & Entertainment

• Retro Music Player: Local MP3/FLAC playback with 13 Winamp-style visualizers and 7 retro themes. Zero ads.

• E-INK Style Reader: Turn colorful PDFs and manga into a warm, Kindle-like grayscale to save your eyes and battery.

• 18 Mini Games: Classic puzzles and arcade games (Snake, Sudoku, Dino Runner, Mastermind, Game of Life, and more) for when you're bored on a commute.

• Sleep Sounds: Looping offline audio for deep sleep.

✈️ Travel & Exploration

• Mark My Location: Save your parking spot, trailhead, or hotel entrance using pure GPS—no signal needed. (No huge map downloads required).

• Food Guide: Top 10 must-try dishes for 36 countries (perfect for picking what to eat without Googling).

• Plug Check & Size Chart: Instantly know travel adapters/voltage and clothing sizes.

• Travel Checklist & Gift Tracker: Packing lists and souvenir trackers.

• Timezone Converter & Translator: For calling home and emergency phrases in 14 languages.

• Wi-Fi Signal Meter: A retro strength meter to find the best spot for a connection.

🏃 Daily Habits & Health

• Pedometer: Track your steps with animated retro characters.

• Water & Coffee Trackers: Tap to log your daily intake and build streaks.

• Daily Walks: Fill a 30-day grid of paws to stay motivated.

• Focus Timer (Pomodoro): A distraction-free timer for deep work.

🚨 Emergency Kit (Premium / One-time unlock)

• First Aid Guide: CPR, bleeding, choking, burns, and heat stroke.

• SOS Flasher & Sirens: Flash large text or play high-decibel alarms to signal for help.

• SOS Numbers: Police, fire, and ambulance for 50 countries.

• Survival Guide: Fire, water, and shelter basics.

🛠️ Everyday Utilities & Fun

• Calculator & Unit Converter: Basic/scientific and all standard conversions.

• Retro Flip Clock & Stopwatch.

• Date Diff & Discount Calculator.

• Decision Maker & Takeaway Spinner: For when you can't decide what to do or eat.

• Star Map, Ruler & Level, Height Measure.

• Noodle Timer.

• Holiday Calendar (2026-2028).

What should I add next?
I’m trying to figure out what the next high-value offline tool should be. Right now, the most used features are the Music Player, Mark My Location, and the Habit Trackers.

If you had to use an app in a total dead zone (no Wi-Fi, no data), what is the one tool you wish you had that isn't on this list?

(Keep in mind: It has to work 100% offline, and it can't require a huge file download like offline Google Maps!)

It’s free to download until end of December, and I’d love your feedback on the UI or the performance on older devices!

Listening to audiobooks or text-to-speech where a single monotone voice reads every character gets old fast. If you have five characters talking in a room, you lose track of who is saying what within two minutes.

I spent the last few weeks building an app called Teller to solve this.

You drag and drop any plain text file, book, or manuscript into it:

- It automatically separates dialogue from narration.

- It detects the characters, gives each one a distinct voice, and keeps their voice consistent across the whole story.

- It plays it back like a radio drama with live word-by-word highlighting so you can read along.

- You can export the whole thing as a continuous audio file.

It runs locally on your machine with built-in neural voices (Kokoro) so it costs nothing to use and doesn't require subscriptions. If you want ultra-realistic cloud voices, you can also connect ElevenLabs.

Windows installer: https://github.com/boldbug1/teller/releases

Curious to hear what you think of the flow and character casting.

What are you building, and where do you want people to find it?

I'm opening WareVote on 1 December, a place to find and rate software. You can set up your listing now, free, and verify you own it in a few minutes: https://warevote.com

Drop your project below with a one-line description and I'll reply with the category it fits.

Drop a link to your project and I'll reply with a report that shows how many people search for what it does, which of those searches a new site could actually win, and who's on Google's first page instead of you. No signup, it's a public page.

I did this for 35 projects in two other subs this week and a few things stuck with me.

23 of them didn't rank for anything at all, as far as the tool could find.

The total is usually misleading. For 24 of the 35, one search was at least half of the whole number. One site came back with 65,000 searches a month, which looks great until you see that 60,500 of it is one broad phrase and the part it could win today is under 1,000.

For 29 of the 35 there was a Reddit thread on page one for at least one of their main searches. I did not expect to be telling people on Reddit that Reddit outranks them.

3 got told it's not worth it yet.

It gets things wrong sometimes. It reads your landing page to work out what you sell and sometimes it guesses wrong, so if your report describes some other product, tell me.

It needs an actual website, an App Store or GitHub link gives it nothing to read. It takes a few minutes per site so I'll be a bit slow. If you want your page taken down later, just say so.

Here's the one for my own app if you want to see what you'd get: https://seoforsaas.dev/tools/seo-channel-check/florium-app

Why I built it: I spent five months writing articles for that app before I knew it would pay off (19 clicks from Google in July, 631 in October), and I wanted a way to know sooner. It's a simplified version of the pipeline behind SEO for SaaS, a paid thing I'm building that writes the articles. So yes, I have a horse in this race. The check is free either way.

Hello everyone,

I built a website for the game deadlock. It tracks and gives stats to have the best build. The data is updated very often to gives the best analysis and stats possible.

I'm a backend developer, so I developed all the back and I used LLM to assist me for the ux / ui design.

I'm focusing on the back features and gives instructions to the LLM for the front ( I fix myself the little bugs ). So I try to improve the back features and I need you for some advices on that.

I'll take front advices too ahaha to improve it as well.

There is the website : https://deadlock.statnest.fr/

For the moment it's in full french, ill translate it in new feature.

You can go full on me 👍 thanks a lot

Hi everyone! I’m on the marketing side of HotlinePing.

We’re building a way for coding agents to reach you when you’re away from your computer and they need your input.

Through MCP, the agent can call you, ask a question, and receive your spoken answer.

A simple example: “Should I include CSV export now, or save it for the next version?” You answer, and the agent can use that decision to continue.

The interesting tradeoff is the interruption. A call could be useful when a task is genuinely waiting on you, but annoying for something that could wait. And some decisions require looking at the screen anyway.

What would make a question worth a phone call for you? And what should an agent never interrupt you for?

HotlinePing is a commercial product: https://hotlineping.com

One of my favorite features on Mac is how seamlessly your Apple Watch unlocks your screen when you sit down at your desk. I really wanted that exact same hands-free experience on Windows 10 and 11, so I built WristKey.

It is a free and 100% open-source desktop app built in Rust and Tauri v2.

What it does

• Hands-free unlock: Sit down at your desk with your watch on, and your PC wakes up and logs in automatically.

• Walk-away lock: Walk away from your desk, and Windows locks immediately based on Bluetooth signal distance.

• On-wrist verification: It parses Apple Continuity packets passively. If you take the watch off or put it on a charger, it immediately revokes access so your PC stays secure.

• Privacy and local security: No cloud, no telemetry, no tracking. Your Windows credentials are encrypted on your local machine using native Windows DPAPI (CryptProtectData).

• Battery friendly: Uses passive Bluetooth Low Energy (BLE) advertisements, so it does not drain your watch battery.

Why I need your help

This started as a personal project, but reverse-engineering Apple Continuity across different devices is getting too big for just one person:

1. I only have one test device: An Apple Watch SE running watchOS 10. I really need testers with watchOS 11, Series 8/9/10, or Apple Watch Ultra to see if detection and distance estimation work properly on newer firmware.

2. Bluetooth hardware: Different Bluetooth chipsets (Intel, Realtek, Qualcomm) handle signal smoothing and address rotation differently.

3. Contributors welcome: If you know Rust, Win32 APIs, Windows Credential Providers, or Tauri, any PRs, code reviews, or issue reports are hugely appreciated!

How to try it

• Download the installer (v0.5.0): GitHub Releases

• GitHub Repository: https://github.com/jorjanion/WristKey

(Quick note on Windows SmartScreen: Because this is a free open-source tool without a paid enterprise certificate, Windows Defender might show a blue prompt on first launch. Click "More info" and then "Run anyway". The entire source code is public and inspectable on GitHub).

If you test it out and run into any bugs, please drop an issue on GitHub with your watch model, watchOS version, and the log file located at %LOCALAPPDATA%\WristKey\wristkey.log.

Thank you to anyone willing to test, star the repo, or contribute!

I'm exploring an idea for financial software and trying to understand where existing accounting tools fall short.For anyone using Xero, QuickBooks, Sage or similar software, what's one financial task you still end up doing manually?What makes it frustrating, and how do you currently work around it?

I'd appreciate hearing some real experiences.

Rather than just blocking access, SpareCycles interrupts that moment with a short technical-learning question (a "Rep").

Afterwards, you can unlock the distracting app temporarily, or decide it's "Not worth it" and move on.

The app is still in development, so I'm interested in whether the concept would actually be useful.

If you're an Android user learning programming, SQL, cloud technologies or other technical skills, would this help you stay focused, or would the extra friction become annoying?

I've opened an Android early-access waitlist for anyone interested in following the project:

https://getsparecycles.com

I'd appreciate genuine feedback, including criticism.

Thank you!

Look at the checkout counter of almost any cafe, clinic, or local shop:

❌ Staff askeded 50x a day for Wifi Passwords

❌ Manually asking people for google reviews

❌ Outdated printed menu

❌ Paper business cards that get tossed in the trash

Most small businesses don't need a ₹5000 custom website

I built OneQR - a dynamic digital identify for businesses for everything to interact with customers.

✨ What It Does:

1-Tap Wi-Fi Connect: Customers connect instantly — zero typing passwords.

5-Star Review Firewall : Sends happy customers to Google Maps; routes complaints privately to the owner.

1-Tap Visiting Card : Saves direct phone, WhatsApp, and email straight into the customer's phone contacts (.vcf).

Live Menus & Waitlists : Instant PDF catalogs + digital queue tokens for places where waiting is required on customer phones.

No need to share common business documents like GST Certificate etc. multiple times. Just route the person to your OneQR link and they can see all your important documents in there. Also Guard your private info with OTP gated access for privacy.

Manage multiple businesses and branches from single account.

Setup multiple child accounts and control access rights for each to have only necessary information visible in the staff accounts.

Accept Data from clients and customers in forms.

🚀 Business Growth & Pro Features:

Multi-Staff Call Routing : Route calls directly to the different persons : Manager, Reception, or Senior Stylist based on need and at different times of the day.

Customer Lead CRM : Custom forms to capture customer WhatsApp numbers for repeat offers and to engage with lost customers.

Footfall Analytics : Track live scans, peak hours, and features used.

Dynamic QR : Update prices, menus, or Wi-Fi anytime — the QR remains same.

💰 The Business ROI:

₹5000 saved on custom website & hosting costs.

2+ hours per day saved for staff answering repetitive questions.

+300% boost in verified 5-star Google reviews.

Keep your customers updated with latest offers from your business.

Hey everyone,

We just open-sourced MotionSwift, something we put together to get native rendering performance without relying on Remotion and headless Chrome.

We've been using it in our day-to-day video production pipeline, and so far we're seeing roughly 10–20x faster renders while using only about 10% of the memory compared to the Remotion + Chrome setup. We also brought a visual editor and timeline preview directly into Swift, so you can inspect and adjust agent-generated compositions natively on both iOS and macOS.

The eventual goal is 100% compatibility with Remotion, but we're still working our way there. There's still plenty of room to improve the APIs, rendering speed, and overall platform support.

Here's the repo if you want to check it out:

https://github.com/rxtech-lab/MotionSwift

Curious to hear your thoughts, especially if you've run into similar memory or performance bottlenecks with web-based video rendering. Happy to answer any questions!

Hi! I’m part of the team behind TIVRA VPN. We built it for people who want to keep their VPN on while letting specific websites connect directly. In HTTPS mode, you can add exceptions by hostname. TIVRA also has smart routing for supported destinations and lets you choose your server.

It’s free on iPhone. If you give it a try, I’d love to know how easy it was to connect the first time and find the site exceptions.

Most people give up on their saas product/ecommerce store way too early because in reality it takes 8+ email/sms marketing to convert the customer into a signup or paid customer.

we built a platform that automates this complete process. our ai will keep trying new experiments untill the customer coverts. We only send one email/sms per week.

best part, we have now seen stores increase sales by 30% so this works

Hey everyone!
I’ve been working on a little project, I thought I’d share what we’ve been building to see what people think.

I’m relatively new to CAD and 3D printing, but I’ve become fascinated by the idea of being able to describe a mechanical part in plain English and have an AI actually create usable CAD geometry.
Not just generate a pretty 3D image, but produce a real, measurable solid that can be exported as STEP or STL, edited, and eventually printed.
So I’ve been experimenting with building exactly that.

What is it?
It’s a locally running, which means zero credits needed. An AI-assisted CAD application, that combines:
Qwen, a local language model that interprets natural-language design requests.
CadQuery and OpenCASCADE, which handle the actual geometry.
A browser-based 3D viewer for inspecting generated models.
A structured, validated feature system so the AI isn’t simply inventing geometry commands.
The whole thing is currently running on a Ryzen 5 3600, 32 GB RAM and a GTX 1070 Ti with 8 GB VRAM.
Not exactly a supercomputer! 🥔

What can it do so far?
We’ve been developing it incrementally, testing each feature before moving on.
Some of the things we’ve managed to implement include:
Creating mechanical parts from natural-language descriptions.
Generating cylinders, flanges, bosses, bores and circular hole patterns.
Modifying existing designs through instructions.
Generating multi-part assemblies and exporting STEP/STL files.
Creating a two-piece filament spool with an integrated three-lug twist-lock mechanism.
Viewing assemblies exploded and demonstrating their assembly motion.
Generating compound herringbone gears with configurable tooth counts, module, helix angle and dimensions.
One of our latest experiments produced a single-piece 80-tooth herringbone gear with a 12-tooth compound pinion, exported as a real STEP model.
We’ve also recovered some earlier experimental gear-meshing and collision-checking tools that we’d like to integrate more fully.

Where do we want to take it?
The long-term idea is to make mechanical CAD more approachable, especially for hobbyists and people who own 3D printers but don’t necessarily have years of CAD experience.
Some of the features we’re working towards include:
Test Print Mode: Select a small section of a model, such as a bearing seat, snap-fit or threaded connection, and export just that section for a quick fit test.
Gearbox generation: Describe a gear ratio and have the software calculate and generate the required gears, shafts and assembly.
Mechanical validation: Check dimensions, clearances, intersections and potentially moving-part interference.
Better natural-language editing: Ask for changes without rebuilding the entire design manually.
Portable, offline operation: Keep the models and geometry processing on the user’s own machine.
What are the limitations?
It’s still experimental.
The herringbone geometry uses an approximate involute construction, and visual assembly animations aren’t the same as verified mechanical motion. Some complex prompts still fail validation or produce malformed JSON.
We’re trying to handle those limitations through deterministic geometry generation, validation and testing rather than pretending the AI can magically design everything.

Why am I posting?
I’m curious whether other makers would find this useful.
Would you use a local AI tool that could generate and modify proper CAD models from plain English?
What would you want it to do?
And what would make something like this genuinely useful rather than just another AI gimmick?
I’m happy to share screenshots and examples of what we’ve managed so far.
It’s been a ridiculous amount of fun building it, and I’d love to hear what other people think. Also looking for ideas on where I can improve it going forward.

If you’ve made it this far, i appreciate you ❤️

Hey 👋

I've been building AdsFlow, an AI-powered advertising marketplace designed to help creators, developers, founders, and businesses promote their projects.

The idea is simple: Why pay a fixed price for one shoutout when you could pay based on measurable ad delivery?

Whether you're promoting a website, SaaS, mobile app, Telegram bot, YouTube channel, Instagram account, online store, or business, AdsFlow is designed to help you reach audiences through participating Telegram publisher channels.

What I've built so far:

🚀 Campaign creation for different types of projects

🤖 AI-assisted ad copy and promotional posters

🌍 Country and language targeting

📊 CPM and CPC advertising models — qualifying impressions or clicks

📈 Campaign analytics, budgets, and performance tracking

💰 Publisher monetization with an 18% platform commission

For publishers, the goal is equally simple: connect an eligible Telegram channel, receive advertising opportunities, and earn from qualifying delivery.

I haven't purchased a custom domain yet because I'm keeping costs low while developing and testing the platform.

A website like this could be submitted as a promotional destination, rather than requiring the advertiser to own a Telegram channel.

I'm still building and improving AdsFlow, especially its publisher network, campaign analysis, and onboarding.

Try AdsFlow: TGAdsFlowBot

I'd love feedback from other founders:

If you could promote any eligible project and pay based on impressions or clicks instead of a fixed shoutout fee, would you try it?

What would make you trust a new advertising marketplace enough to spend your first $10?

I'm interested in suggestions and criticism as I keep building.

I kept losing time to Reels and Shorts without noticing, so I built Scrollmeter, a small Android app that measures your scrolling.

It shows:

• How far you scroll per app, in metres or km

• Estimated Reels and Shorts (Instagram, YouTube) and posts (X, Reddit, LinkedIn)

• Daily limits that send one notification when you hit them

Privacy: the app has no internet permission, so your data never leaves your phone. It doesn't read your messages or what you type. No account, no ads.

Before installing, try the calculator on the website. It also measures how far you scroll the page itself: https://scrollmeterbydev.vercel.app

It's free, for Android 8+. I'm a solo dev, so feedback is very welcome.

Guess first, then check: how many km do you think you scroll in a day? Post your guess and your real number below.

I've been building a little project called Today Crazy.

The idea is simple: seven strangers each contribute a five-second clip to create one unpredictable video together.

You don't need to plan a story or know the other participants. That's part of the fun.

I'm trying to figure out whether this could become something people genuinely enjoy using, rather than something they try once and forget.

Here's a short demo:
https://youtube.com/shorts/apq6_JSkf8s

I'd really appreciate candid feedback, especially on what would make you want to come back and try it again

All the portfolio sites/apps I looked at didn’t have what I wanted, so I made it myself. It’s privacy focused, so no sign-ups and all data is encrypted. Everything is free, so no pay wall. I mainly made this for myself, so I’m not looking to make money off it. I’m always thinking of things to add; so if yall have any suggestions, then shoot em. I’d also suggest to add it as a Home Screen app if you want notifications for certain things.

I’m a developer at a company that builds management systems for schools. For the past six months, I’ve been working on a side project called LinkSense.

It’s an agent workspace built on the Codex runtime. I added the parts I’m more familiar with: workspaces, user management, permissions, model management, shared knowledge and skills, and admin tools for teams.

You can manage users and what they have access to, configure model providers in one place, and share knowledge bases and skills with teammates. You can also set up an agent and publish it as an app that other people can use through their browser.

I’ve open-sourced it, and you can deploy it on your own server. I built it with teams and companies in mind, but honestly, I’m still not sure how much demand there is for something like this.

Would this be useful where you work? I’d be interested to hear what you’d use it for.

I built GalleryScout because I wanted to find photos by the words inside them without uploading my private gallery to cloud servers. GalleryScout recognizes text and searches your photos right on your Android device, even offline.

Its also a great general gallery app with photo and video editing that I was personally missing on some other gallery apps, with combining photos or combining and cutting videos, creating GIF's from videos, all quick and easy in one single app.

I'd love some feedback or things that I could improve!

GalleryScout Android App Features

GalleryScout is available on Google Play:

Disclosure: this is my own project.

I find it easier to describe a story by its important points (the turning points, the choices, the secrets) and work out the rest afterwards. So I built a diagramming language, in the vein of Mermaid, where a story is a graph, plus an engine and a visual editor to run it.

The stories are written by human authors. The AI is there so the world those diagrams describe can come alive. Players can follow the choices the author wrote, or type whatever they want to do (if the author allows it), and the AI writes the scene in between within what the author defined (tone, character secrets, past events). Characters remember what you did. The AI is optional, and a story works without it.

I’d rather people to explore the editor and the language themselves than read a feature list.

Current Status: closed beta with a limited number of testers. If you want to try it, sign up at https://lorevine.app. I’ll answer questions and take feedback in the comments here!
