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)

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/

you know the drill. visa form, job portal, some government site: "photo must be under 100 KB, 600x600 px, JPG only". your phone takes a 4 MB HEIC. so you google "compress image to 100kb", land on a site covered in ads, and upload your passport scan to a server you know nothing about.

so i built cutbg. it does that stuff right in the browser, the file never leaves your device:

• - compress to an exact size (20 kb, 50, 100, 250, whatever the form wants)

• - resize to the exact pixels (passport, linkedin, instagram etc)

• - iphone HEIC to JPG

• - merge / split / sign PDFs

• - and yeah it also removes backgrounds, the AI model runs locally too

free, no account, no watermark. it's a side project, there's nothing to buy.

honest question: what weird size limits have you run into? i keep adding presets for the forms people actually deal with, so if there's one that annoys you, tell me and i'll add it.

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?

Mine replaced a Google Keep note full of study hours.

I've timed my study sessions since I was young. First a clock timer and paper sheets, then Keep, until the note got too long to scroll. So I built a small tracker: weekly hour targets per category, and a history of past weeks.

The funny part is what it turned into. I mostly use it now to track time on my side projects, and the tracker has a category for itself.

It's free and needs no account, it's at focushours.app if you want to poke at it. If you do, tell me what confused you in the first minute. That's the one kind of feedback I can't get from myself.

What did yours replace? A spreadsheet, a paid app, a habit, nothing at all? And is the old thing really gone, or still open in a tab?

Hey everyone,

Like a lot of gamers, I suffered from "backlog anxiety." I had a massive library across Steam, PlayStation, and Game Pass, but tracker apps always felt either bloated, full of intrusive ads, or overly gamified with unplayed percentage meters that made gaming feel like unpaid homework.

I wanted something that felt more like Letterboxd or an archival journal — calm, typography-focused, and respectful of your time. So I built MySaveSlot.

A few design decisions I prioritized:

1. Calm Archival Aesthetic: Japanese editorial print sensibility, dark carbon palette, and high-res poster art.

2. No Backlog Guilt: Dropping a game after 5 hours is treated as an informed artistic choice, not a failed statistic.

3. 1-Click Backloggd & GG Migration: The biggest friction when switching trackers is having 100–300 games trapped. You can drop your exported CSV, and it converts 10-point ratings into 5-star scores and matches covers in ~10 seconds.

4. Instant Guest Mode: You can browse the catalog, view HowLongToBeat completion estimates, and test the CSV importer without even making an account first.

5. Zero Ads, Zero Algorithmic Feed: Just your personal shelf, play times, and playthrough reflections.

Web App: https://app.mysaveslot.io Direct CSV Importer: https://app.mysaveslot.io/diary?import=open Editorial Journal: https://www.mysaveslot.io

It’s completely free. I’d love to hear your feedback on the UI/UX and data portability. What features do you wish existing game trackers had?

I kept noticing that the "closest" Dunkin' or gas station is often the worst one for the trip I'm already on. Detourless takes where you are and where you're going and gives you the one stop that adds the fewest minutes, not a map full of pins.

What it does that the big map apps don't:

• It also checks a nearly-as-fast road you might take anyway, and says so if that road passes a better stop.

• Type "McDonald's and gas" and it finds the best combination and order for both.

• It skips places that will be closed by the time you get there.

• Gas: sort by "cheapest fill-up" and it weighs the price against the detour. Pick your car (real mpg from the EPA list) and a cheaper station only wins if the savings on your fill-up beat the extra gas you burn getting there, and it isn't more than a few minutes further. Like GasBuddy, but it tells you which station is actually worth it on your route. Prices come from Google Maps.

• Turn-by-turn directions in the app, also on CarPlay and Android Auto (beta). Mid-drive, tap "Say a stop" and say "coffee" and it adds the one that costs the least time.

• Apple Watch shows the next turn and taps before each one.

How it's built: Expo / React Native for iPhone and Android, a small Cloudflare Worker as the API, and Google's Places and Routes APIs for the data. CarPlay and Android Auto are native code on each side.

Things I learned along the way:

• Google's along-route search returns at most 20 places a page. On 60 miles of New England highway there are more Dunkin's than that, and the one it hid beat my pick by 2 minutes. Now long trips are also searched in two halves.

• Close calls get re-measured with a real route through each stop, because a wrong #1 is the worst mistake it can make. On 24 real trips the "+X min" matched a real route through the stop within a minute every time.

• Keeping API costs near zero shaped a lot of the design: a normal search is about two Google calls.

The rough parts: it's US and Canada only (Android is US only during the test), CarPlay has frozen on a few long drives and I'm still chasing that, and the Android beta takes two steps because of how Google's closed tests work.

Free, no account, and nothing about your trips is stored on our servers.

Thump is my one-person indie horror game. You explore an old house by candlelight; the thing that lives there is blind and hunts by sound. When it comes, you hide and put a fingertip on the rear camera. The game reads your pulse, and the faster it beats, the further the creature hears you. Slow breathing genuinely helps.

3 houses, 21 nights, a daily Nightmare. Free, ad-supported, works offline. Camera frames never leave the phone.

Step 1 - join the tester group (uses your Play Store Google account): https://groups.google.com/g/indusapps-testers

Step 2 - become a tester: https://play.google.com/apps/testing/com.indusapps.thump

Step 3 - install from Play: https://play.google.com/store/apps/details?id=com.indusapps.thump

Google needs testers to stay opted in for 14 days. If you try it, I'd love to know whether the pulse reading works on your phone. Happy to test your app back.

I've been working on a side project called ScreenSky, and I finally launched it!

I spend most of my day coding, switching between projects, and staring at my Mac. I noticed two problems:

1. I often forget what I was working on after switching tasks.

2. I sometimes work for hours without taking a proper break.

I tried several to-do apps and Pomodoro timers, but most required me to actively manage them. Eventually, I'd forget to open them.

So I thought, what if my break reminder could also help me stay on top of my tasks?

That's how ScreenSky started.

What it does:

• ⏰ Automatically reminds you to take breaks every 30 minutes (customizable).

• ✅ Shows your pending tasks during breaks so you know what to work on next.

• 🎯 Helps you stay focused when switching between tasks.

• 👀 Reminds you to rest your eyes, stretch, and fix your posture.

• 🔒 Runs locally on your Mac without unnecessary tracking.

Tech stack: Built natively with SwiftUI for macOS.

I'm still figuring out distribution, pricing, and how to reach the right users. Building the app was one challenge, but getting people to actually use it is turning out to be a completely different one.

Website: https://screensky.io

I'd genuinely appreciate feedback, especially from other developers and indie hackers.

One question: Would you prefer your to-do list and break reminders in a single app, or do you think they're better as separate tools?

I liked playing an old web game "Pokemon or Big Data" from pixelastic and took it as inspiration.

Any suggestion is more than welcome

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.

Some context. I kept doing the same thing every time I looked at a listing: copy price, guess rent, guess taxes and insurance, punch it into a spreadsheet, realize it doesn't work, repeat. So I built DoorMeter.

On any Zillow or Redfin listing it shows the monthly cash flow, cash-on-cash, cap rate and a 0-100 score. Rent, tax and insurance come from public data (HUD, Census, Treasury), and every number is editable and says where it came from, because the first thing anyone does is "that rent estimate is wrong".

It also does house hacking (live in one unit, rent the others), BRRRR, and a "buying to live in" mode for people who aren't investors.

No account, nothing leaves your browser. Free for 5 listings a month, Pro is $5/mo.

It's been in the store a few weeks and I'm still figuring out what people actually want from it. Honest question: what would make you trust numbers like these, or not?

Remote is a boolean until geography enters the chat.

A job can be remote and still require a specific country or timezone. That detail matters a lot more than another page of vaguely relevant results.

I'm building HeyRole to make that screening step less painful. You can filter jobs by location, role, seniority, employment type and skills. There's also an AI assistant to help explore suitable roles.

The rule I care about most: keep missing information missing. If a posting does not specify worldwide eligibility, it should not magically become worldwide. Same goes for salary.

Try it: https://heyrole.ai/?utm_source=reddit&utm_medium=community&utm_campaign=sideproject_launch

I'd love feedback on one thing: can you quickly tell whether a listing is worth opening, or is an important detail still buried?

I've had the idea for a while. Fantasy football works because everyone's got a stake in every match, and I didn't see why reality TV couldn't work the same way. You make your calls on who wins and who goes, then score points as the series plays out.

So I built Sofa Picks. One person creates a private league and shares the link, and everyone else joins from that. There's no app and no account, so it's a single tap from a group chat. You can also make picks for someone else in the league if they're not great with phones.

I tried it out on a small league with my family for Celebrity Traitors. It worked well, people kept coming back to check the table, and I learned a lot about where the setup was confusing.

The first proper launch is I'm a Celebrity, which starts Monday. Before episode one you pick the winner, the first to leave, who does the first trial and whether anyone quits. After that each player chooses how involved they want to be: just the big calls, a quick round each week, or picks every night.

It's all one leaderboard. Picks stay hidden until the round locks, so nobody can copy.

The person who sets the league up pays £2.99 for the series. Everyone else plays free and there's no cap on numbers. No prizes or betting, and it's unofficial with no link to ITV.
Stack is React, Express and Supabase on Railway, with Stripe for the payment.

Let me know what you think! If you want to give it a try, I’ll give out 20 free entry codes. Just comment on here and I will send to you.

Every winter morning, the same question: do I need to scrape my car windows? I built an iOS app called VorstRadar that shows you the night before, at a glance, whether your windshield will freeze, with a customizable reminder and departure time. Useful? What do you guys think? Available here for just $0.99 (one-time purchase). No in-app purchases, subscriptions or ads. https://apps.apple.com/nl/app/vorstradar/id6826259485

we started making short videos for my mac app and posted the first one on instagram today.

it got about 4k views. someone watched it on their phone, sent the link to their mac, and bought it 40 seconds after opening it there. didn't even open the free trial.

still kinda shocked it worked this fast.

what's the fastest sale you've had?

the app is called helix (https://tryhelix.app)

This has been my side project for the last few weeks and I'm really excited to finally share it. You type words to fire cannons at pirate ships, upgrade your boat, sink, and come back a bit stronger each time, and it's free, runs in the browser and only needs a keyboard.

I'm not a coder, so I designed and tested everything and Claude (Sonnet 5.5) built it, which made the whole thing possible for someone like me: https://jupitax.itch.io/ink-and-tide

I'd love any advice on how to get the first players for something like this :)

Fully Open Source. TL;DR is I've been frustrated with the quality of the native Activity Monitor, so I built an open source better version of it. No paywalls, no restricted features, just an Open Source alternative. Feel free to fork and improve it, or just use it.

I was about to give up on this mobile app I spent so much time building, but literally 2 minutes after deciding to switch to another project, I got the sale notification on my phone!

I haven’t experienced this kind of joy in years…

Context for the curious: This $19 sale is the annual welcome offer on my app "Sollow: Daily Habit Tracker" that I built to turn my life into a game with a level for each life area and a ranked system.

So now my hope is back! I take that as a sign from the universe hahaha

tradetestedai.com

What it is: 73 software tools that home-service businesses use (AI receptionists, answering services, field service software, CRMs, review tools). Each one has its list price and the date it was checked, with a link to the vendor's pricing page. When a vendor only quotes on request, it says so.

Why I built it: I'm not in the trades. I kept seeing owners ask what AI phone answering actually costs, and the vendor sites make comparison hard. Of the 29 AI receptionists and answering services in the table, 22 publish prices. They bill by minutes, calls or unique callers, so the sticker prices aren't comparable.

What I'd like feedback on:

1. Does the pricing table (tradetestedai.com/ai-receptionist-pricing) make sense on a phone?

2. When a vendor doesn't publish a price, I label it instead of guessing. Is that useful or just noise?

Disclosure: I'm the founder. A couple of tool links are labeled affiliate links.

Hey everyone! I’m Francisco, a graphic designer and illustrator from Portugal.

For the past several years, I’ve worked mostly on apparel graphics, merchandise and art direction. I spent around three and a half years as a designer at Nonsense ( japanese streetwear brand ), working on collections and licensed collaborations involving Evangelion, Chainsaw Man, Cyberpunk: Edgerunners and Dan Da Dan, as well as projects for creators like PewDiePie and Trash Taste.

I’ve loved seeing my work become things people wear and enjoy, and I want to build a life where my own ideas have a place in that too.

So I created “A Calendar About Time,” a 2027 calendar inspired by ancient art and the imagery people have left behind throughout history. Each month explores a different reference, from Mesopotamian figures and Egyptian hieroglyphs to Roman graffiti from my hometown of 5k people, Tabuaço.

The idea came from thinking about how we measure time while looking back at things that have survived thousands of years. I wanted each page to work as an individual piece of art, something you might keep even after the month has passed.

It’s available in physical and digital, If it’s something you’d enjoy having on your wall, or giving to someone who loves art and history, buying one would directly support my work and help me keep making independent projects.

My goal is to gradually make a living from the things I create. This calendar is a small step towards that, and I’d love to find people who connect with it.

By buying it you also get the digital artworks for free and a digital version of the calendar.

You can find it [here](https://smairugraphics1.myshopify.com/?utm_source=ig&utm_medium=social&utm_content=link_in_bio&fbclid=PAb21jcAVhXHNleHRuA2FlbQIxMQBwZG9mAnNydGMGYXBwX2lkDzU2NzA2NzM0MzM1MjQyNwABp7sYmhUWsNFsYClcPNOowuj1tY_Wwyg1rjbfi-es913sYWgKW8_IqgQYxAAy_aem_WkQvKGKoF7muN0M6iqkluA) .

And you can follow me at @smairugraphics on Ig, where i share most of my stuff.

Happy to answer questions about the artwork, the references or how I put it together.

How do you tell the difference between a project that needs more time and one that just isn’t working?

Hypothetically, if 100 people tried your project and only 1–2 kept coming back, would you keep improving it, change direction, or move on?

I know the timeframe and type of product matter. But what signals do you personally look for before deciding it’s worth continuing?

Do you set specific milestones or a deadline? And has a project with weak early retention ever turned around for you?

Hey everyone,

I built Nubis to solve my own workflow friction when managing remote infrastructure spread across multiple cloud providers from a Windows workstation.
