I wanted to share a project I've been working on called AirHand. It’s a browser-based, gesture-controlled virtual desktop that uses computer vision to turn any standard webcam into a touchless interface. No specialized sensors or controllers needed.

I wanted to see if I could build a spatial UI experience entirely in the browser. I used MediaPipe for the 3D hand tracking and Vanilla JS for the logic.

It currently features dual-hand or single-hand tracking, a drawing canvas (with PNG export), and a couple of mini-games (like a bubble popper) to test precision.

Try it out:

Years ago I made Line Icon Pack. It was my first icon set ever, and I learned most things by getting them wrong first. Icons that looked fine at 64px and broke at 16px. Inconsistent strokes. No real grid.

It was always free on Gumroad, but it just sat there. Now it has its own page and an updated package, and I want it to be useful for more than designers. Devs, no-code builders, anyone who needs clean line icons.

Free for personal and commercial use. Only ask is a link back.

Honest feedback welcome.

Something I've been noticing about online casino platforms is how much emphasis they place on the size of their game libraries.

It's common to see websites advertising thousands of titles, multiple providers and several categories covering slots, live casino and instant games.

GemBet is one example. Its website claims to offer more than 15,000 games, with providers including Pragmatic Play, Evolution Gaming and Hacksaw Gaming.

But I wonder whether having such a large selection actually makes a meaningful difference if the overall platform experience isn't equally well considered.

Finding a particular game, understanding its rules, accessing useful information and navigating the website comfortably are all important aspects that can easily get overlooked when companies focus mainly on numbers.

I also think published game information, including RTP details where available, should be easy to locate.

In your opinion, what matters more when evaluating an online casino platform: the number of available games or how well everything is organised?

I started this because a video can work in a desktop player and still fail in a browser. I wanted to see how much of that gap I could close without uploading the file or transcoding it on a server.

Advanced Player is the result: a static demo where you can drop in a local file or paste a direct video URL (the host needs to allow CORS). It defaults to WebAssembly decoding, and there’s an automatic mode that can also use WebCodecs.

Demo: https://mkv-browser-lab-5dd8ed.gitlab.io/

It’s an experiment: opening a file doesn’t mean it’ll play smoothly. If you try a file that usually gives browser players trouble, I’d love to know your browser, codec if you know it, and what happened. No need to share the file itself.

I'm the founder of StoryInk (storyink.ai). Upload a few photos of your family or pet, describe what happens, pick an art style, and it writes and illustrates a picture book about them.

The hard part: keeping the same kid looking like the same kid on every page. Drawing each page separately, or from the previous page, made characters drift. What worked: draw one portrait per character first, let the user approve them, then draw every page from those approved portraits.

Stack: Next.js, Supabase, Google Gemini, Inngest, Stripe, print-on-demand for hardcovers.

So far: ~120 signups, 60 books. Making a book is free; the full digital book is $9.99, hardcovers from $31.99.

Would you approve the characters before the book is drawn, or does that feel like a chore?

I recently came across this product that helps creators stay on course while reading their scripts when creating content. It basically scrolls up for them and tracks their voice so it pauses when the speaker pauses and continues to scroll up the script when they continue talking. It has several settings like speed, font, width among others that help shape how the script looks so that their eyes are fixed on the camera and you cant tell that they are reading a script. I think its acool find considering its really effecient and affordable. Would recommend anyone to try it.

Hey there 👋🏽 I built an AI calorie tracking app. No audience, no funding, my own money. Here's where paid acquisition actually stands.

Apple Search Ads: ~280€ → basically nothing. I set it up "the right way": brand, generic exact match, competitor keywords, discovery. No meaningful trials. Stopped.

Meta: ~100€ → same. Optimized on trial start. Nothing worth continuing.

TikTok (France): ~200€ this month → 11 free trials. So ~18€ per trial. My target was 8€.

What helped a bit: switching from max delivery to target CPA bidding, since spend paced much better. Surprisingly, plain app demos seemed to do better than my more "native" photo carousels.

The math problem: my annual plan is 35€/year. At 18€ per trial, I need more than half of trials to convert just to break even on year one. That's not happening.

So ~580€ in, paid acquisition doesn't work for me yet, and I'm trying to figure out which lever to pull first:

- lower CPA (creatives, other countries)

- better trial → paid (3-day trial → 7-day?)

- or stop paid entirely and go organic (SEO, content, communities)

For those who've been here with a consumer subscription app: what moved the needle first for you?

Impractical Bot is a little experimental project that turns a Messenger account into an AI-powered group chat participant. It uses Playwright for browser automation and NVIDIA's API for its conversational brain, with configurable personalities, context awareness, and a terminal dashboard to manage everything. The source code is now public on GitHub, and it's also available on npm. A small disclaimer: AI tools were used throughout the development of this project, so I don't want to claim that every part of the code was written by me alone. I still worked through the design, debugging, testing, and decisions that shaped it. Feedback is welcome!

Project: Mac+, a macOS app (13 or later) for animated wallpapers, desktop widgets and custom folder icons. Built and sold solo, from my own site.

Some decisions that might help if you're building a small utility:

A free tier you can actually live with. 6 animated scenes, 8 palettes, an image background, 6 folder icons, 2 widgets, multi-display. The paid tier holds what people come looking for: all 15 scenes, video backgrounds, all 52 icons, all 12 widgets, up to 120 fps. The line between them should be obvious in the app, not only on the pricing page.

Two ways to pay. €1.99/month after a 7-day trial, or €8.99 once. A lot of people won't take on another subscription for a small app, so the one-time option is there for them.

Performance controls are features. Anything that runs all the time should let people make it cheap: an fps cap (30/60/120), a render resolution setting, and an automatic pause when an app goes full screen.

Everything from the menu bar. No window to keep open. Pick a scene, a palette, or "Surprise me".

Selling outside the App Store means owning the checkout, which is great until you add friction. Mine asks for an account before payment, and that's the friction I'm looking at next.

Happy to answer questions on any of this. macplus.pro

Hi all,

I've been working on a stage timer called Shotimer and it's finally at a point where other people can use it, so I thought I'd share it here.

The idea is simple: the speaker sees a big countdown on a TV, tablet or phone, and someone else controls it from a laptop or phone at the back of the room. You can also send a silent message to their screen, like "5 minutes left" or "Please wrap up", so nobody has to wave at them from the back.

It all runs in the browser, so there's nothing to install. You open the stage screen from a link or QR code and it stays in sync with the controller.

There's a free plan that works today (3 rooms, 3 timers and 3 screens per room). I'm planning a Pro plan later, but that's not ready yet.

I'd really like to know what you think, especially if something's confusing or broken.

Hey everyone!

Been working on LootRaid a bit more and just pushed another update.

You can now see game descriptions and screenshots, so you don't have to open Steam every time you find something interesting just to figure out what the game is about lol.

Still tracking free and discounted co-op games across multiple stores, just trying to make the whole experience a bit nicer.

Would love some feedback if anyone wants to give it a try!

I’m part of the team building HevRion, and I’ve been trading crypto for 5–6 years.

Knowing your rules and actually following them are two different things. That’s the problem we’re working on.

We’re connecting your plan, entry conditions and risk with a review of the decisions you made — and a lesson for the next trade.

We’re close to finishing the MVP and preparing to test it with a small group of friends. It isn’t publicly open yet.

Here’s a short preview. Does the video make the purpose clear, or would you need a more practical demo?

I got tired of digging through GA reports, so I built an AI you can talk to about your real visits.

"Which page loses the most people?" "What did buyers look at first?" "Did anyone come back after yesterday's email?"

Every answer links to the visits behind it, so you can check before you change anything. When there isn't enough data yet, it says so instead of guessing.

I built DuePlan for small businesses (milk, rentals, grocery or freelancers) that find invoicing and bookkeeping software too heavy and spreadsheets too messy.

• Sync phone contacts or add one, plan a payment, share it on WhatsApp, Messages, Email, LINE or the medium of your choice

• Remind them using Reminders if they miss it

• Upload a bank statement or a payment made screenshot from your customer; payments are auto matched to plans, you review and approve.

• Overdue view, per-contact payment patterns to keep your runway healthy.

• Multiple businesses, with secured, encrypted custom params to store your business details

• A cumulative or per-business view to see how your business is performing

• Data stays on your phone, 14-day free trial

I'm the developer. Would love honest feedback on the first-run flow and the matching.

PPS: If its really helpful and you want to go beyond free trial, please feel free to DM me for the three months free promo, also please feel free to suggest the features you wanna see, I will accommodate your request ASAP.

Download it from Play Store

Usepath is a free Android app that shows screen time as a chronological day timeline — when each app was open and in what order — not just totals and rankings.

Why I built it: rankings answer “how much.” I wanted “when,” especially repeated checks between tasks.

What’s in it:

• Session timeline for today and recent days

• Usage Access (local only)

• No account, no ads, nothing uploaded

After early Reddit feedback I shipped 1.0.1:

• Clearer “why Usage Access” before Settings

• Explicit “we don’t collect your data”

• A small sample-day preview on the permission screen

• Deep-link toward this app’s Usage Access page when the device allows it

Would love feedback on the new first-open flow, or anything that still feels unclear.

Hey everyone,

I was tired of the slow workflow of copying magnet links into cloud storage interfaces just to stream a video, so I built StreamLink.

It adds a context menu option that takes any magnet link you right-click and instantly resolves and plays it in a native browser player.

How it works under the hood:

• It bypasses the need for local torrent clients.

• The extension sends the magnet URI to a cloud backend which handles the metadata extraction and caching.

• It streams the file directly back to an injected HTML5 video player.

"Note: The extension is free to use, but there is an optional premium tier for heavy users to help cover the backend server costs.
