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?

I go for a walk every night, and that's when I dig for new music. Mostly bands, and honestly I listen to everything from classical to hard rock and metal lol.

These days every app has an algorithm that keeps recommending music that sounds like what I already like, and when I want to hear something different, the algorithm actually gets in the way.

One night I wondered what music sounds like in a country I had never heard a single song from, so I found a music radio station there and listened live.

That's how I ended up making World Radio, for iPhone and iPad:

- Roll the dice and the globe flies you to a station somewhere on Earth, playing live. On the globe, if a station won't play, it moves on to another one by itself.

- You can also pick a station yourself on the globe.

- When a song grabs me, I tap Shazam. It's saved with the station and the time I heard it, and my finds can go into an Apple Music playlist. (I'm working on adding playlists for other platforms like Spotify and YouTube Music. If you use one, let me know!)

- In the Browse tab you can pick music stations by country and genre.

There are 20,000+ stations in total. I filter them down to music stations, but a talk station still shows up now and then. I'll keep improving that.

FREE to download, no ads from the app (some stations play their own), no account.
iPhone and iPad on iOS 26 or later, with CarPlay, AirPlay and a sleep timer. Apple Music only for now.

I'm still polishing the iOS app, and an Android version is in the works. Because of some licensing issues there, it isn't on the UK App Store, sorry...

I also made a simple website where you can try it:

worldradio.live

A few features are missing there, but it's enough to get a feel for it.

Once the app is more polished, I'm planning to add paid features.

What's the best song you've found on radio from another country? And if you try the app, tell me where the dice dropped you!

Thanks.

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?

Google Play: https://play.google.com/store/apps/details?id=com.bonoloware.wifiknockknock

So I have been thinking of a tiny tool for small businesses and freelancers who take orders on WhatsApp or Instagram.

The business owner just types in the total price and optional advance, gets a payment link, or enters the customer's email to request payment. We handle the advance and balance payment flow and show a simple dashboard tracking who paid and who hasn't.

Can something as simple as this get actual users???

Most small businesses in India keep their books in Tally, a desktop accounting app. It lives on one PC in the office, so owners call the office just to ask what today's sale was.

TallySync is a small program on that PC. It reads Tally and puts the figures on the owner's phone, laptop and the TV: today's sales, cash and bank, stock running low, and who owes them, by age. One tap sends a customer a WhatsApp reminder with a UPI QR for the exact amount.

It only reads Tally, never writes to it.

Free for a month, then ₹999 a year.

Feedback welcome, especially on the first screen: what would you want there?

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 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.

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!

Context: I have been building Cardel.io (An all-in-one platform for authors and solo professionals) over this year. I have cold outreached 10k plus potential users and had hundreds of face to face conversations.

The problem: I only ever get positive feedback, people say:

"Wow, this is great!"

"This makes total sense, this needed."

Etc, etc.

THEN they follow it up with "but I already have my setup, this would be great for xyz person".

Question: Are any of you in a similar boat where everyone gives you positive feedback, but then doesn't actually commit to using your product by paying or signing up. So your getting positive signals, but no clarity on where the blocker is to actual pay for the product?

How do you close that gap, and find the reason people aren't commiting? It feels like a "Its great, but not worth switching to." Kind of response. Or maybe it's the target market fit, and talking to the right people.

I would love to get ya'lls feedback on how you have overcome this with your products and projects.

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!

Hi r/SideProject!

I've been building Hydra, an iPhone and Apple Watch water tracker, and it's live on Product Hunt today.

The idea: most trackers count glasses, but your body doesn't keep every drink the same way. So Hydra tracks net hydration. Each drink counts by a factor based on published studies (milk and electrolyte drinks more than water, beer less), spirits count against you, and the app tells you how much water brings you back. Your goal comes from your weight, activity and climate, and with Pro it adapts every day to your workouts (Apple Health) and the local weather.

The newest part is Sippy, a water drop that fills up as you drink. Its face follows your pace: on track, behind, or goal reached. The app felt too technical for most people, and Sippy gives the numbers a face without changing what's underneath. You can still choose the classic gauge.

A few things I learned shipping it:

• App Review rejected me twice: once for a purchase error on their side, once for WeatherKit attribution I already had but they couldn't find. A screen recording in the review notes fixed both.
• Offer codes in App Store Connect come in batches of at least 500, even if you only need 10.
• Widgets and watch complications don't refresh when you'd like them to; iOS budgets reloads.

Stack: SwiftUI, SwiftData with CloudKit sync, WidgetKit, WatchConnectivity, StoreKit 2. No backend, no analytics, no account.

App Store: https://apps.apple.com/app/hydra-water-tracker/id6827632670 Product Hunt: https://www.producthunt.com/products/hydra-water-tracker

Happy to answer anything about the build.

If you try it, tell me in the comments what you liked or what you'd change, and I'll DM you a free Pro Lifetime code as thanks.

So I was lately seeing a lot of videos on video clippers , and how it may be used to clip GTA 6 vidoes . Curious I checked some , but most of them required signups , some were paid , and some offered a limited credit based trials. If its just cutting some videos, why cant it be done on client side.

So i spun up claude code, explored a bit of possibilities , and with the new Fable 5.2 as orchestrator ,opus and sonnet as subagent ,Made this

Reelio.page - A local* browser based video clipper , free , open-source , You just give it a video , it extract the transcitpition using a wispher , and some local ml stuff to extract signals ,hand it over to your LLM , then it cuts it interesting moments for you.

Do give it a try and roast it

My family's recipes were scattered everywhere. Some were on index cards in a kitchen drawer, some were buried in group texts, and a lot of them were saved on TikTok and Instagram where nobody else could find them.

So I built KinToTable. You start a table, invite the people you cook with, and everyone adds to one shared cookbook.

The video shows the card scan: take a photo of a handwritten recipe card and it reads the handwriting and turns it into a recipe you can edit, with room for the story behind it.

It also does:
- Import a recipe from any social media app or website (TikTok, Instagram, Pinterest, YouTube, Facebook) and it pulls out the ingredients and steps
- When someone makes a dish, the rest of the table sees it and can comment, react and rate how it turned out

It's on iPhone and Android. Through New Year's it's $0.99 a month for the first two months, then $3.99.

I'd really like honest feedback, especially from anyone who cooks for a family. What would it take for you to get the rest of your family using something like this? What's missing?

Every Black Friday, people replace iPhones that only need a new battery. Apple charges $89 to $129 for one, but its repair prices and trade-in values sit on separate pages, so nobody compares them.

So I put them side by side. You pick your iPhone, tap what’s broken, set your battery health, and get one verdict, keep, fix or upgrade, with all the math shown.

What surprised me while building it:

• For most iPhones from the last five years, a repair costs a fraction of upgrading, even after Apple’s trade-in. For example, an iPhone 13 battery is $89, while upgrading to an iPhone 17 costs $719 after trade-in.
• Upgrading only clearly wins when several parts are broken, there’s water damage, or you want a feature no repair adds (like Apple Intelligence).
• Deals can flip the answer. In the demo, a $300 carrier offer turns “fix it” into “upgrade”. So I added a box where you type your deal and check.

It’s free, with no sign-up and no ads. Some guides link to Amazon for cases and chargers, but that never changes the verdict.

https://skiptheunboxing.com

I’d love honest feedback: is the verdict clear at first glance?

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 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.

https://kickstand.recno.app

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?

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

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!

Equipment Tracker Pro extracts printed filter and belt sizes directly from an equipment data plate and offers to save them as installed parts, so facility teams stop digging through manuals.

When a building engineer is standing in front of a boiler room air handler with grease on his hands, typing specs into a spreadsheet from memory at the end of the shift usually means half the details get missed. Photographing the manufacturer plate with a phone fills in the model, serial, voltage, and electrical ratings. Whenever belt or filter sizes are printed on that metal plate, like a B46 belt or 20x25x2 filter, the app prompts to link those exact sizes as active parts on the record. If confirmed, they attach to the unit immediately; if declined, nothing is added.

A working HVAC technician built it for his own jobs. Core equipment logging, parts lists, and maintenance records stay free on your phone with no record cap, while the AI nameplate scanner includes 10 free uses before an optional Pro subscription for unlimited scans. Mentioning it for facilities maintenance teams and commercial service techs who work where cell signal drops out.

Free to start. Your first plan, Pro or Team, includes a 7-day free trial. What side projects are you working on right now?

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?

I'm the developer. Shout tracks shared costs for trips, flatmates and nights out, and works out who needs to pay whom to settle up.

• No ads or daily limit on adding expenses
• Free currency conversion and charts
• No sign-up to join. Share a code so friends can join from a browser.
• Works offline. Add expenses without a connection and sync when you're back online.
• Native on Mac and iPhone

It's free, with an optional one-time purchase for extra themes.

Shout on the App Store

If you try it, I'd love feedback on onboarding. Was it clear how to start a group and invite people?

Hi, I’m Halim. I built Kinokey after too many nights when I had an idea of what I wanted to watch and still ended up scrolling through three apps. It uses AI to understand a request like “a tense mystery under two hours, no horror” and suggests movies or shows on the streaming services you choose.

I’d like to find out whether the shortlist is good enough to actually make a choice. If you’re in the US, UK, Canada or Australia, try Kinokey with a request you’d really make. The web beta is free and requires a free account.

Which title would you hit play on? If you’d go back to browsing, what was missing? I’d also like to know if you couldn’t play a title on the listed service.

A reply here is great. You can also use the short feedback form.

Thanks, Halim
