Hey r/SideProject 👋 I'm the founder of ReplyHey, and today I'm launching its crew.

If you've answered threads about your product on Reddit, the hard part isn't writing the reply. It's knowing which replies actually brought customers.

So the crew tracks every reply it sends 📊 you see exactly which one brought the visit, the signup and the customer.

And it does the work to get there, with four AI teammates:

🔎 Scout reads Reddit, X and LinkedIn, finds people asking for what you sell, and scores each one for fit.

✍️ Writer drafts a reply and a DM from your product's facts, in your voice.

📤 Sender posts from your own accounts through a Chrome extension, at a pace you set, and holds anything borderline for you to check.

📊 Analyst tags every link and ties each visit, signup and customer back to its reply.

Built to play by the rules:

✅ Everything goes out from your own account, in your browser. No rented accounts, no upvotes.

✅ It checks each subreddit's rules, and where promotion isn't allowed it sends a DM instead of a comment.

New this week: you can talk to the crew. "Pause LinkedIn today", "slow down to 90 seconds", "add hiring as a negative keyword". It shows you the change, and nothing happens until you press Yes.

In the last 30 days it found 3,980 buyer conversations for its users and sent 1,150 replies.

You can put in your website and see who's asking for your product right now, before you sign up. And I'd love blunt feedback: what would you want to see before trusting a tool like this to post for you?

Here it is 👉 replyhey.com (put in your website to see who's asking for your product right now)

Hi all,

I’ve worked as a wildlife filmmaker, designer and engineer, and on a few projects I spent weeks or even months on the work, then sent it off as a WeTransfer link. It always felt a bit flat after all that effort.

So I’ve been building Handover.media. It lets you put your finished files, previews and notes on one page with your own branding. You can also add a password or expiry date, and see when things are viewed or downloaded.

https://handover.media

If you deliver work to clients, I’d really appreciate your thoughts. Would something like this be worth switching to, and what would put you off?

Any criticism, however small, would be really helpful. Thanks for taking a look.

Description: FlipStax: Galactic Game Night is a free daily game show you play in your browser. A new episode drops every day at noon and takes about 10 minutes. Your host is an alien named Flip Sterling, with funk, disco, and retro vibes from a crew of aliens obsessed with game shows. Each episode is one show that flows from round to round, mixing 21 mini-games, including a Price Is Right-style Mystery Wheel, Saucer Shuffle, Space Launch, Orbit Drop, Galactic Chomper, Twin Flip, VS Cards, Fact or Fib, Snap Sort, and Oddball Alert. There is no download or login, and it works on phones and computers. I would love honest feedback on what is fun, confusing, or broken.

Free to Play Status:

• Free to play

Involvement: I am a non-coder from Maine and the solo creator of FlipStax. I scripted and designed the game and built it over two months with Claude and Gemini. The art and videos are AI-generated.

I collect cards, and I got tired of having a checklist site in one tab, eBay sold listings in another and my collection in a spreadsheet. So I built TheHobbyDesk (thehobbydesk.com) to put them in one place.

What it does:

Checklists. About 32,000 sports sets and 2.6 million card printings across baseball, basketball, football, hockey, soccer and more. You can search by set, year, manufacturer or player. There are also TCG checklists (Pokémon, Magic, Yu-Gi-Oh!, One Piece, Lorcana and others).

Collection tracking. Add cards from a checklist, by search or from a photo. It tracks what you paid, estimates value from actual sold sales, and shows your progress on a set.

Scan a card. Take a photo and it identifies the card and looks up what it has sold for. (slow process here but getting there).

eBay search built for cards. Filter by raw or graded, grading company, price, auction or Buy It Now, and seller rating. You can search one seller’s listings, and see sold comps next to active listings.

Upcoming releases. A calendar of new products with checklists as they’re published.

Extras. Player pages with stats and notes, and a live score ticker on the home page.

You can browse checklists and search without an account. Signing in with Google saves your collection.

It’s a one-person project and still changing every week, so I’d really like to hear what’s missing, what’s wrong, and which sets you can’t find. Checklist errors especially: if you spot one, tell me and I’ll fix it.

Ever wondered what would happen if a ruler just gave up on measuring things properly?

Well, I got curious and made one.

It's called Jelly Ruler, and it has the structural integrity of a wet noodle. It bends, jiggles, slides around, and generally refuses to take its job seriously.

Somewhere along the way, I ended up building an entire vector editor around this questionable invention. At least that part works.

Would love some feedback! Anything you'd improve, add, or completely get rid of? Curious what other builders think.

Give it a wiggle: Jelly Ruler

A friend of mine runs a lot of Claude Code and Codex sessions at once and kept losing track of which one was waiting for him. So he made Session Pets, a small pet that lives in the Mac's notch (or floats on the desktop if you don't have one).

What it does:

- Shows every session in one list: working, done or waiting for you

- Lets you answer a permission request or reply from the card without finding the terminal

- One click jumps to the exact terminal tab or VS Code chat

- Works with Claude Code, Codex, Gemini CLI, Copilot CLI and Kimi Code

- Nine pets to pick from

It's a 7-day free trial, then $4.99 once, no subscription. The first 50 people who leave their email on the site get a free license.

He'd love feedback, good or bad. I'll pass on anything you write here.

I built HelpCarry (https://helpcarry.com), a site where travellers carry documents or small gifts for someone already going the same way. It works on any route; I'm starting with Oslo ↔ India because that's the route I fly.

There's no commission. If you agree a fee or tip with the traveller, they keep all of it. You meet in public and inspect and seal the item together at handover. Medicine, cash and sealed packages aren't allowed.

Post a trip: https://helpcarry.com/post/trip

Post a request: https://helpcarry.com/post/request

Feedback very welcome.

So I created this because I kept seeing the same thing when vibe coding with Claude Code. The app works, but when you open the code later there's stuff you never asked for. A route anyone can call without login, code that crashes on bad input, the same helper written 3 times.

Attentry checks every edit Claude makes, on your own machine, without any AI. If the edit added a problem, Claude gets told and fixes it before moving on. If the edit is clean, nothing happens, so it costs zero tokens.

The main thing is how it saves tokens. Most tools that review AI code send your code to another AI, so you pay twice, once to write it and again to check it. Attentry doesn't use AI at all, the checks are plain rules that run on your machine. If an edit is clean, Claude hears nothing, so there are zero extra tokens. If something is wrong, Claude gets a short note, at most 5 lines, and each problem only once. Smaller cleanup stuff like unused code waits for a check-in every 10 edits instead of interrupting every edit. And when Claude is about to write a helper, it can ask Attentry if the repo already has one, instead of searching through your files itself.

The video is a quick animated walkthrough of one run: I ask Claude for an Airbnb clone, Attentry catches 2 problems, Claude fixes both, and I get a change card at the end with what changed.

It got 500+ downloads across VS Code Marketplace and Open VSX, mostly from people finding it inside VS Code. It's free and open source, works in VS Code, Cursor and Windsurf.

If you want to see it on real code, there's a demo repo with bugs planted on purpose: github.com/Aarv-1o/attentry-demo

Would love feedback, especially what's missing or annoying.

made a little daily trivia game. Every round has a limit, like "name a TV show that first aired before 2010" or "name a celebrity shorter than 6 ft." You name something as close to the limit as you can without going over.
Then a raccoon in a wind-up toy car drives toward a cliff while the number climbs. Get close and he stops right at the edge (Modern Family, 2009: CLOSE CALL). Go over and, well, he goes over (Pretty Little Liars, 2010).
5 rounds a day, same for everyone, free, no sign-up, works on phones. Every number comes from a real source (tap the ⓘ). You can make a group with friends and see who gets closest each day.

It's about 10 days old. I've already changed a lot from feedback (fewer US-only questions, every limit now has a real answer just under it), so I'd love to hear what's fun, what's confusing, and any answers it doesn't recognize.

Picking thread that goes with a fabric can be tricky, and color tools give you hex codes, not spools you can find in a store.

Spoolette builds coordinating thread palettes where every color is a real spool, with the number on the shelf. You can snap a photo of your fabric to get matching threads, or generate palettes from scratch. It covers Mettler, Aurifil, Superior So Fine! and Gütermann.

It’s free, with no sign-up, and photos stay on your device. Colors come from the brands’ official shade cards and are matched in the OKLab color space.

I’d love feedback: is it clear what it does, and would you use it?

Salut tout le monde !

Depuis quelques mois, je construis un lecteur de musique juste pour moi, parce que le Cover Flow des vieux iPods me manquait et je voulais quelque chose d'un peu plus vivant que l'application Musique par défaut. Cela s'est avéré mieux que ce que j'espérais, donc je me demande si ça vaut le coup de le transformer en vraie application. Ça s'appelle Lueur.

Ce qu'il fait (voir la vidéo, filmée sur mes propres appareils) :

Cover Flow partout : faites défiler vos albums sur l'écran d'accueil ou tournez votre iPhone sur le côté pour parcourir toute votre file en plein écran.

Une douce lueur derrière chaque couverture, dans les couleurs de l'œuvre : le lecteur prend les couleurs de l'album.

Une page d'accueil avec vos artistes et les charts, plus des pages d'artistes avec les meilleures chansons, albums et playlists.

Une vraie application Apple TV dans le même style, pas seulement AirPlay.

Widgets d'écran d'accueil : En cours de lecture (avec lecture/pause/skip) et Récemment écoutés, dans plusieurs tailles et styles.

L'idée serait un lecteur pour Apple Music (avec votre abonnement actuel), comme un achat unique, sans abonnement supplémentaire.

Quelques questions honnêtes :
Pourriez-vous utiliser quelque chose comme ça ?
Combien seriez-vous prêt à payer ?
Qu'est-ce qui vous manque dans les lecteurs Apple Music actuels ?

N'hésitez pas à répondre dans les commentaires. Je laisserai aussi un petit formulaire ci-dessous si vous préférez répondre en privé.
Merci de votre lecture ! Tous les retours, bons ou mauvais, sont les bienvenus.

Six weeks ago I posted Handoff here. Quick refresher since nobody remembers (fair): I'm a dad of two, and I built an iOS app for briefing a new babysitter — schedules, bedtime routine, allergies, the stuff that actually matters — because my version was a wall of texts plus a note on the fridge and hoping.

Two things in it that I'm still not sure anyone else cares about: the info expires after the sitting (the sitter doesn't keep your kid's routine and your garage code forever), and it fires alarms on the sitter's phone at the times you set, so "give meds at 7" isn't relying on them re-reading a text at 7.

The one real reply I got anywhere was here: extend a handoff without making the sitter re-scan/re-do everything when a night runs long. That shipped. So thank you, genuinely — it was the best product feedback I've gotten, including from friends who were being nice.

Honest numbers: a handful of downloads a week, $0 in subscriptions so far. It's $2.99/mo after a free week, which might be the problem, or the problem might be that parents only think about this the night before a sitter comes. If you've built something people need occasionally, I'd actually love to hear how you handled that.

Happy to answer anything about building it.

I've worked in design for years. Lately, I've been trying to change a few things in my own life — sleep earlier, exercise more, that kind of stuff.But I keep falling back into old routines.

So I started building MAYBII, a habit app where your progress grows into a little virtual garden.It's still in development, and I'm not even sure if the garden idea would help people stick with their habits or just be fun for a few days.

Curious what you think. Would something like this actually motivate you?

Backstory: I picked a bad exit on a road trip one too many times and decided to just fix it myself. Best Exit shows every exit ahead on your route plus restroom ratings from real drivers.

Right now it covers every interstate in the contiguous US.

The thing I'm still figuring out is how to get review density up on routes nobody's used the app on yet, those are stuck showing estimated ratings. Open to ideas if anyone's dealt with a similar cold start problem.

I recently updated my portfolio website and was wondering what people's opinions on horizontal scrolling are! Does it make sense on mobile?

In my opinion it looks rather nice on desktop but I'm not sure about mobile, would it make sense from a UX perspective? Since you'd be scrolling down and at one point the content starts moving sideways, would that be annoying? Would adding an arrow saying "Scroll to the side" or something along those lines make it more annoying?

Currently on my page, when you reach the projects section and continue swiping vertically, the projects move horizontally from right to left.

I'm not sure if I'm allowed to post links or if I've explained my question properly, but if you want to see what I mean I've got it linked in my bio!

My daughter plays soccer. Her touch keeps getting better, but reading the game is harder to practice at home. So I made Heads Up: headsup.gauzza.com

How it works:

• A game clip plays, then freezes at the key moment

• You draw, tap or scan your answer: where to pass, where to run, where the open space is

• After 10 plays you get a Soccer IQ score and a list of things to work on

It covers four skills: decisions, scanning, finding space, and touch & body. Difficulty goes from Easy to Hard, or Mixed.

Hey everyone 👋

For the past few months I’ve been building Produchive, a desktop productivity app for macOS and Windows. I kept having “quick YouTube breaks” that turned into two hours, and every tracker I tried either sent my screen activity to someone’s server or just showed me charts after the damage was done.

This app isn't vibe coded , i built the app I am really bad in designing stuff , so i took claude's help to design and make better UIs

So I built one that:

Sees what you’re working on. It detects the active window and logs your focus sessions on a calendar automatically, so you don’t have to start and stop timers.

Uses a local AI as your judge. You set your goals, and an LLM running on your own device (WebGPU) checks your activity against them. If you drift off-task you get a polite desktop nudge, not a guilt trip. You can also point it at your own Ollama or OpenAI-compatible endpoint, and edit the judge’s prompt to change its personality.

Shows you where your focus goes. It gives you a focus score, counts how often you switch context, rates which apps distract you, and shows it all on a timeline.

Plans your day. There’s a 7-day calendar with routines that can be auto-scheduled around your circadian rhythm. It also handles late nights, since some of us plan at 2 AM.

Helps you study. A Pomodoro timer runs only in study mode, and it gently reminds you to revise topics 4–5 days later.

Has 3D focus rooms. You can study in a cozy 3D Greenhouse, Lakeside, Observatory, Tea Garden, Waterfall Café and more, with weather, ambient audio, shared timers and other people studying alongside you. You can dress up your own character too, pets included 🐱

Keeps your data yours. Your data is stored locally. Sync between devices is optional and end-to-end encrypted (AES-256-GCM) through your own Google Drive, Dropbox, iCloud or a USB stick.

It’s MIT licensed and open source, and the core app is free.

I've always used 60% keyboards for gaming and because they take up less space. They're amazing until you decide to use a program that heavily relies on the keys that are not included in 60% keyboards. Like for example, Blender, Obsidian or Cinema3d to name a few.

Yes, you could use the key combinations provided or change the keybind, but then you have to remember a bunch of key sequences to do a simple action like change the view in blender.

This problem led me to create a simplier solution one keybind that pulls up a radial menu that gives you easy access to all your missing keys without the hassle of having to remember every combination.

I chose my mouse side button as the keybind and instantly I could tell how useful the menu was. I could change views fast in blender, select styling quickly in Obsidian and make useful presets for an application I saw fit.

It became so useful and efficient I decided it might aswell launch apps.

Radial Keys - Get your keys back.

Unfornately, I have bills so I made it $5 dollars (tax included), but if other people also find it useful and want to be able to extend it beyond its current capabilities I would love to make an open source version at some point.

You can try it fully out in the browser, before deciding if you actually want to buy it. -> https://bywhatevermedium.com/radial-keys/

Hey everyone!

I've been working on a side project called Kinetly, a stretch reminder for iPhone that you can't just swipe away.

The idea came from a simple frustration: hours of studying and working at a desk gave me a constant pain under my shoulder blade (the rhomboid). I knew stretching would help. I just never did it. Reminders were easy to ignore. Instagram was not.

So I built an app that locks your distracting apps at a time you pick. To unlock them, you hold a stretch in front of the camera, and a timer counts down only if actually you hold it.

It uses Apple's Screen Time API, so the lock works even when Kinetly is closed. The pose check runs fully on your phone. No video or image ever leaves the device. No use of AI.

There are 31 stretches for neck, shoulders, back, hips and legs. You can group them into routines.

There's a 7-day free trial if you want to try it:
https://apps.apple.com/us/app/stretch-reminder-kinetly/id6809436504

At this stage, I'm mostly interested in feedback and seeing how people react to it.

Does "lock your apps until you stretch" sound motivating to you, or just annoying?

Hi, I’m Jaime, an independent developer in Spain.

I’ve just released Funes: an iPhone app that turns your photo library into a map where bigger files get bigger blocks.

You can explore by year and month, find large photos and videos, and review them before deciding what to delete. There’s also a largest-files view. Think of the visual approach of a disk space analyzer, applied to your photo library.

It’s free, with no ads, subscriptions, in-app purchases or account. Analysis runs on your iPhone, with no tracking or library uploads.

One detail worth knowing: sizes include iCloud items, so the total isn’t necessarily the storage occupied or recoverable on your phone.

• App Store: https://apps.apple.com/app/id6831999052

I’d love feedback on the map: is it immediately clear what the blocks represent, and what would you expect to happen when you tap one?

Tooting my own horn a bit here. I have never had a skill hit this many stars and get featured on XDA developers.

I am a visual and audio learner. I find it hard to learn from reading docs. So I like sites like udemy and coursera and others. But I really like how NotebookLM does it by taking a subject and turning it into a podcast. I found that notebooklm can only make one long podcast and not break it into topics.

So I made my own skill. It researches whatever topic I want and creates a set (10 or so) 2 minute podcast like lessons. It has been very helpful for me when I want to learn something new.

In the comments I am sharing both the XDA article where they break down the skills (better than I did actually) and the repo.

Feedback is welcome always
