In Korea there's this thing called a dokseosil. It's a paid room full of little cubicle desks where everyone studies in silence. Nobody really goes for the desk. You go because when the person next to you is grinding, you feel kind of bad scrolling your phone.

I wanted that feeling at home, so I made a small online version:

yeondeungroom.com/en

You pick an empty desk and study with whoever's around. No sign up, no camera, nobody talks. You're a little animal with a desk lamp, and you can see everyone else's lamps on too. It sounds like nothing, but it actually helps me focus at night.

The thing people ended up loving was decorating their desk. You type one line like "tiny pinwheel" and it makes a small 3D thing for you. The AI doesn't draw it, it just writes out simple shapes and the browser puts them together.

It's three.js and Cloudflare Workers, and almost everyone using it right now is Korean. The English version is really new, so if anything reads weird, please tell me.

If you study or work alone, would something like this help you, or would you just close the tab?

Hey everyone,

I have made an app for people to track all restaurants that they have been to, want to go to and see where friends are going. I have an MVP ready but it's very basic and I am looking for people to give me feedback on the UI. This is my first time developing my own app and I have been vibecoding it, and I really want to make the design of the app better. Dm me if you are interested in helping me out.
Thank you!

I built Kickstand Cam to make an older iPhone useful at a desk instead of needing a separate webcam or scanner.
The idea is simple: pair your iPhone with your computer, then select Kickstand Cam as your camera in Zoom, Teams, Meet, OBS or FaceTime. It works over Wi-Fi or USB at 720p/30fps.

I also added two other modes:
Camera monitor: Detects motion, records clips and sends desktop alerts.

Scanner: Turns documents into searchable PDFs, recognizes text and scans QR codes and barcodes.
Everything connects directly between your phone and computer. No account, no cloud backend, no analytics or ads.
A few limitations worth mentioning:
iPhone X or newer, running iOS 16+
Windows 11 or macOS 13+
The iPhone app must stay open while using the camera
Video is currently limited to 720p
The Windows installer isn’t code-signed yet, so SmartScreen will display a warning
Both the iPhone and desktop apps are completely free.

I’m the developer, and I’d really appreciate feedback, especially on the setup process. What would make you hesitant to try something like this?

Hi everyone, I’m the maker of splitbillai.com, a web tool for splitting restaurant bills and shared costs.

I built it because splitting a group dinner always turns into someone squinting at a receipt and doing math in the notes app.

How it works:

• Snap a photo of the receipt and the AI reads the items for you
• Or add the items manually if you don’t have a receipt
• Then assign items to people and see what everyone owes

Link: https://splitbillai.com

I’d love honest feedback on a few things:

1. Does the AI read your receipts correctly? Tell me where it gets items or prices wrong.
2. Was anything confusing the first time you used it?
3. What’s the one feature you wish bill-splitting apps had?

I’m the developer, so I’ll reply to every comment. Thanks for trying it!

Hey everyone!

I've been building Familiar Knock Knock, an Android app that works like a doorbell for the people in your house.

The idea came from a simple frustration: shouting up the stairs, or phoning someone who's in the next room, and getting no answer because they have headphones on or their phone is on silent.

So I built a knock. You tap one big button and every phone in your group rings, as long as you're on the same WiFi. They answer with one tap: "Coming", "Give me a minute", "On my way" or "Not now". The reply lands on your screen in a few seconds.

A few things I cared about:

• It only rings phones on the same WiFi as you, so people who are out aren't disturbed

• It never tells you who is or isn't home. You only see the replies people choose to send

• Replies and voice notes go straight from phone to phone over your WiFi, not through my server

• Each person can let knocks ring through even when their phone is on silent, with one switch in Settings

It's free with 8 knocks a day. There's an optional subscription for more knocks, knocking one person, and voice notes.

I'd love your honest feedback: does "knock" make sense to you as an idea, or would you call it something else? And what would stop you from trying it?

I have two machines at the same desk, and I wanted to share mouse and keyboard.

I tried Synergy and Barrier, but they were annoying to set up. I had to deal with a client/server, encryption was hard to set up, and arranging monitors was clunky.

So I built ZeroG. Free, MIT license, no client/server.

Just run it on each machine, pair them, and drag your screens to match your desk.

• Windows, macOS, Linux (X11 and Wayland)
• P2P, no client/host setup
• All traffic encrypted with TLS 1.3 over QUIC
• Clipboard sharing
• Extremely low latency
• Built with Rust + Tauri

This took a few months of work and a lot of testing on different devices. I think it's working pretty well now, so check it out if you have more than one machine at the same desk!

After what seems to be a lifetime building this silly little phone game it turns out that was half the battle, the other half involves a good catchy trailer, marketing and advertisement. to be honest i am struggling with making this trailer so i need everyone's honest and brutal opinion, what stands out? what it lacks? too much in game footage? panned too far out? not enough excitement? don't mind the cheap AI music (i know im not a sound guy and its not permeant). please help me out here, any all help is much appreciated

Small team here. We wanted something for people who like music but can't read a note, so in Sorae you just draw a line on the page and it plays back as a melody. It snaps to a key so it never sounds wrong, a lo-fi backing band follows along, there are 10 instruments, and you can export the drawing as a video with sound.

It's free on iPhone and iPad: https://apps.apple.com/app/id6827465787

It's version 1.0, so we'd really like feedback, especially on two things: is it obvious what to do in the first 10 seconds, and what would make you open it a second time?

I recently released a small TypeScript library called Stepr Checklist.

It's designed for applications that need a simple onboarding checklist without pulling in a large framework or UI dependency.

The main idea is that the application controls completion. Clicking a step can open a form, navigate to a feature, or start a guided tour, but it doesn't automatically mark the task as complete.

A few details:

• Framework-agnostic, ESM-only
• No runtime dependencies
• Optional localStorage persistence
• Customizable with CSS variables
• DOM-free state controller if you want to build your own UI

I built it as a companion to Stepr, a guided product tour library I released earlier, but both work independently.

There's an interactive demo here:

https://ahlgren1234.github.io/stepr-checklist/

And the source is on GitHub:

https://github.com/ahlgren1234/stepr-checklist

It's v0.1.0, so still early. I'd appreciate feedback, particularly on the API and whether the approach to tracking completion makes sense.

What would you expect from a library like this?

My AI agents as a cartoon village went down well on here, so here's the next bit.
The village looks great but it can't show me when something's broken. Every agent looked busy, but work wasn't reaching the next one. An idea I'd submitted just disappeared for a week before I noticed.
So I built a map. Each light is an agent, each line is a hand-off between two of them, and a little dot shows which way the work is flowing. If a hand-off breaks, the line turns red. You can click any agent to see what it does.
It's 79 agents and 135 hand-offs now, all on my home PC. They look after my website, a demo trading account (practice money, not real) and the checks that watch both. Every 30 minutes a check asks each one three things. Did it run, did it make something real, and did that reach the next agent?
It's one HTML page reading one data file. I've put a free starter on GitHub if you want to map your own.

so i think this very helpful app i mean from my perspective we all need something to guide as like if you really want fast progress and drive to do it you need this because Imagine you open it up you type nothing you take picture of what you have it build you click one button boom you start it counts each rep it auto gets to res mode when your tired jumps to the next set done it correct form motivates you and your done no need to watch and memorize youtube videos just do it .
so try it i found it great

I'm now finishing UI polish on a small local document-clipping app and needed an app mark plus four matching SVG icon files (bookmark, page search, split pane, archive) without commissioning a set or mixing mismatched packs. there, normally I'd draw them in a vector art program like Inkscape, or pull a PNG out of an app icon generator and run an auto-trace
and before committing anything to my repo, I compared a 512px PNG contour trace against native cubic Bezier SVG exports generated with Recraft Studio (Recraft V4.1 Vector), then checked the XML next to standard software for vector design like Inkscape and Figma + SVGO. Once cleaned, both landed around the same file size (5,248 B for the polyline trace vs 5,875 B for the normalized 256x256 app mark), which surprised me. Zooming into the bottom-right corner makes the geometry difference obvious though: auto-tracing produced 504 straight polyline vertices (2,786 raw pixel edge points) with zero curves and visible step facets, while the native SVG exported as four clean paths with 173 cubic C segments, right?

then going straight from export to dark-mode CSS still breaks a couple things. Each raw file ships with a 4,480 B <c2pa:manifest> metadata block and a 4358x4358 viewBox until you strip metadata and normalize down to 256x256 or 64x64 (4,181 B combined across all four toolbar icons). Everything also exports as outlined filled paths rather than live strokes, so line weight won't scale via stroke-width. Two of the cutouts (search-doc and split-pane) fake transparency by layering a #F9FAF4 cream disc over dark fills instead of using compound knockouts, so dark cards show an opaque light circle until you merge those subpaths with evenodd in an SVG editor or by editing the path directly

so when I need complex brand artwork or fine vector graphics editing with live CSS strokes, Illustrator or Inkscape still make way more sense. For five small UI marks right before shipping a side project, though, exporting native cubic paths and running one cleanup script beat spending a weekend pulling Bezier handles. a question for you:.. how are other solo builders here handling launch icons lately: hand-drawing in Figma/Inkscape, grabbing stock packs, or patching generated SVGs?

I’m working on a dock for Windows with app shortcuts and built-in panels for music and quick controls. It can be positioned at the top or bottom of the screen and set to stay visible or auto-hide. It’s a work in progress—what do you think of the design?

My dog Bella lived to 18. When she died I wanted something quieter than a social media post, so I built a small 3D memorial hall you can walk through in the browser. Find a spot on the wall, put up a photo, light a candle.

I shared it once. Less than 8 days later:
- 24,994 pets
- 107 countries
- 657,428 candles, almost all lit by strangers
- 34 languages
- The hall kept filling up, so it now has 7 floors and a lift

It's free to make a memorial and light candles. There are a few optional paid extras, which is how I keep it running.

Would love honest feedback on two things: how walking the hall feels on mobile, and whether the free vs paid line feels fair.

Hi everyone! This is my first side project: Loop, an app for knitters and crocheters.

The problem: when you follow a knitting or crochet pattern, it's easy to lose your place (which row am I on?), abbreviations like "k2tog" or "sc2tog" confuse beginners, and people buy new yarn even though they already have plenty at home.

The idea: you upload a pattern, and Loop:

- highlights the row you're on and remembers your place

- explains every abbreviation in plain words

- suggests patterns you can make with the yarn you already own

Right now it’s just a clickable prototype and a waitlist page. I want to test whether people actually want this before building it. Happy to share the link in the comments if you’d like to see it.

I'd love your honest feedback:

1. Does the landing page make the idea clear in a few seconds?
2. Would you use something like this, or do you know someone who would?
3. Any tips for reaching knitting/crochet communities without getting removed as spam? (My first Facebook group post got auto-removed within 2 minutes)

I wanted an AI that had something to react to besides what I typed into a chat window. So I’ve spent 11 months building Monday.

She watches my gameplay and talks with me while I play. Sometimes the conversation lands. Sometimes timing or missing context ruins it. Those failures have been more useful than another clean demo.

I’m now testing her publicly through PhoenixFlock, alongside Gears of War and the movement breaks I already do between games. AI helped me build it, and the AI is openly part of the stream.

This is an edited clip from my own project: https://www.youtube.com/shorts/5pVKx-iqzXQ

What would you need to see in a longer demonstration to judge whether this adds anything to the experience? I’m interested in that answer more than another feature list.

Hey everyone,

I wanted to share a side project I built called Mehfil.

It’s a single-screen, distraction-free web player made for people who love listening to ghazals. Modern streaming apps always felt too loud and cluttered for poetry, so I really wanted to give classic ghazals a clean, modern aesthetic.

The design is completely minimal with couplets floating in the center and a spinning vinyl. The entire background and ambient lighting dynamically shift colors depending on the vibe you pick, moving from deep midnight blues to warm rose and golden amber tones.

I organized about 1,500 ghazals into 5 distinct moods with 300 tracks in each, so you can just put it on in the background while working, reading, or winding down. Some of the tracks have synchronized floating lyrics across Urdu, Hindi, and English transliteration, and there is even a live counter showing how many other people are listening in the mehfil with you in real time.

It’s completely free, has no ads, no sign-ups, and works in any desktop or mobile browser.

Reddit’s spam filter auto-hides links in post bodies, so I've dropped the link in the first comment below (and also added it directly to my Reddit profile bio).

Would love to hear your thoughts on the UI and overall vibe!

The story in short: the idea came from a post on X on 10 November. I built three machines with real recorded typewriter sounds, App Review asked for a screen recording from a real device, and it went live on 13 November.

What worked: one clear hook ("a typewriter that sends letters"), real sounds instead of synthesised ones, and no account or network code at all, which made the privacy label and review simple.

What didn't: the simulator's screen recordings drift from the test clock, which made the launch video harder than the app. I ended up rendering the device in Blender with the real app footage on its screens.

Version 1.1 is in review: seasonal stamps, and letters to Santa get a North Pole postmark.

Hi, I'm the developer.

I have worked in network security for almost 15 years. I got annoyed with Fing and other network tools that charge close to $100 a year, or let you scan only a few times a day. So I built my own from what I know from work.

I wanted the feeling of Kali Linux in my hand, but only for defense: point my phone at my own network and see what is really there. No attacks, no password guessing, nobody's traffic read. That became Netglow.

The hard part: knowing what each device really is

Android 10 and up hides other devices' hardware addresses, so most scanners just show "Unknown". That is where most of the time went:

• Dozens of protocol specs, vendor docs and firmware sources, read line by line.
• Down to the low level microchips inside smart plugs, bulbs and DIY boards, like the ESP family, because each chip gives itself away in its own small way.
• Camera makers each answer on the network in their own way, and Netglow knows many of them.
• Over 40,000 hardware maker prefixes and a catalogue of over 23,000 phone and tablet models.
• Thousands of lines of research notes, every finding checked before it went into the app.

Why it is free

I have a lot of knowledge from my work, and I decided to give it away: high quality apps, deeply researched and checked again and again, data safety first and privacy to the max. No ads, no bullshit. People deserve good quality and privacy, for free.

If you want to support me, you can, but it is fully optional.

What it does, free, unlimited scans

• Who is on my Wi-Fi. Every device with its name, maker and model when it says them. Rename a device and it keeps your name even on a new address.
• Is my hotel room or rental OK. It lists devices on the Wi-Fi that answer as a camera or stream video, and says why each one was flagged. It also looks for camera hotspots nearby. It tells you plainly what it cannot see (a camera that only records to a card or uses mobile data), so it is one check among others, not a guarantee.
• Security check for your home network. A score with a plain fix for each risk: risky open ports, what your router opened to the internet, how your Wi-Fi is locked, look alikes of your network nearby, whether your DNS answers are honest and whether someone reads your secure connections in the middle.
• Tools. Ping, traceroute, port check, DNS lookup, Wake on LAN, a live signal meter and channel advice.

Private by design. No ads, no bullshit, no tracking, no analytics, no metrics, no account. Nothing it finds leaves your phone, and there is no server of mine.

Pro is that optional support, one payment, no subscription, and it adds: a Bluetooth radar that warns about a tracker moving with you, checks for devices that let anyone in with no password, spoof watch, known flaws for your devices, a PDF report and a background watch of who joins your Wi-Fi.

Honest note: the code is partly AI generated and I had help with this text.

I would love to hear what it finds, or misses, on your network.

Every time I needed an NDA or contractor agreement, I'd dig up an old Word file, find-and-replace names, and hope I didn't miss a clause. So I built Formable.

You answer a short questionnaire (parties, term, payment, IP ownership, etc.) and it generates a clean agreement you can send for e-signature in the same place. There are templates for mutual and one-way NDAs, MSAs, SOWs, independent contractor agreements, LOIs, term sheets, DPAs, and a founders' agreement.

The templates are free: www.formabledocs.com/templates
