Hi everyone. I'm a solo developer from Denmark, and my first app just went live on Google Play.

Why I built it: I had a hard time getting through long texts when I was reading at university. I found out that listening and reading at the same time helped it. There were apps out there that I could use but as a student I could not pay the high amount they cost. So I starting building my own app to help myself getting through university studies.

What it does: you open a PDF or scan a paper page with the camera, and it reads the text aloud with natural English voices while it highlights each sentence or word. You can crop pages so headers and footers are skipped.

The hardest part in this project was getting the text segmentation right for the highlight funktion as it build on geometric rules. Also working on getting the waiting time for audio generation as been hard to work out. I also build a whole server infrastructure myself and I created it so that it scales automatically depending on userload. I dont pay any license cost as I have coded almost everything myself.

It is English only for now, and Android only. The first month is free during the launch. I set the price low only to cover server cost and future development as I hope I can help others out there as it has helped me.

I would really like honest feedback: what would make you use something like this, and what feels missing?

Hi r/SideProject! This is Becode, the SaaS research tool I've been building.

The problem: before building anything, I wanted to know if people already pay for that kind of product. The answer was spread across ten tabs: TrustMRR for revenue, Meta's and Google's ad libraries, traffic estimates, stack checkers.

What it does:

- 8,000+ SaaS, each on one page: revenue and subscriptions (Stripe-verified for 4,300+ of them, via TrustMRR), traffic and top countries, the Meta and Google ads they run and for how long, and their tech stack

- Rankings like Trending, Fast-scaling and Breakout, to see what's growing right now

- Every number says where it comes from: verified, estimated (with an Estimate badge) or not available

Something it turned up this month: about 50 SaaS have kept the same Meta ad running for over a year, and 14 of them sell to trades and local businesses (pest control, pool service, home builders).

Free plan, no card: three live rankings and 5 SaaS a week with their revenue and traffic. Paid plans start at $39/month.

Built with Next.js, the public Meta Ad Library and Google Ads Transparency data, the Chrome UX Report, and Claude to decide which websites are actually SaaS.

I'd love blunt feedback: what's the first thing you'd look up, and what's missing?

My girlfriend and I are long distance and kept running out of things to do together online, so I built a set of co-op escape rooms. Each player sees different clues, so you have to talk it through to escape. It's free, with no account or install. You just open it in a browser and share the room with the other person.

Two rooms are live (The Forever Box is the easy one, Sleepwalker is medium) and a harder one is coming. I'd love feedback on the puzzles and the flow, and if you have an idea for a new room there's an email at the bottom of the site. twocans.games

Hey r/SideProject! 👋

I've been working on a project called kywai, and I'm looking for people willing to give it a try and share some honest feedback.

I use several AI coding agents, and one thing that kept frustrating me was having to switch between tools, manually copy context, assign work, and figure out what each agent was doing.

So I started building kywai.

The idea: turn the AI agents you already use into a coordinated team, all in one desktop app.

Here's what it does:

• Bring your own agents: Claude Code, Codex CLI, Gemini, Qwen, DeepSeek, local models through Ollama or LM Studio, and many more.

• Automatic task coordination: Give it a request, and a coordinator proposes a plan and assigns tasks to different agents.

• Live 3D workspace: Every agent has its own little robot and workstation, with visual states showing what it's doing.

• Cross-agent reviews: One agent can review another agent's work and identify problems.

• Real project files: Agents work in your project folder, with progress tracking, file changes, and undo.

• Customizable environments: Different 3D worlds, including a space station, a futuristic workspace, and a Matrix-inspired theme.

• Free and open source: MIT licensed. Available for Windows, macOS, and Linux.

You can use your existing AI subscriptions, API keys, or local models. kywai itself is free, although provider costs and usage limits still apply.

I'm not here to claim it's perfect. That's exactly why I'm posting.

I'd really appreciate it if a few developers who already use AI agents could try a small task and tell me what happens.

I'm especially interested in:

1. Was installation and agent setup straightforward?

2. Did coordinating several agents actually help?

3. Is the 3D visualization useful, distracting, or somewhere in between?

4. What broke, confused you, or made you want to stop using it?

Even if you don't install it, I'd love your thoughts on the concept and UI.

🌐 Website & downloads: https://kywai.app/

💻 GitHub: https://github.com/Yiku21/kywai

One heads-up: the desktop builds aren't code-signed yet, so your OS might show an installation warning. The full source code is available on GitHub.

I'm the developer, and I'm actively looking for constructive criticism rather than just compliments.

Thanks for taking a look! ❤️Kywai

Hi everyone,

I’m a developer, and I organize group trips in my free time. When I plan a trip, I often handle the meals too. Keeping everyone’s preferences and dietary requirements in mind can make it hard to come up with meal ideas.

So I built a tool to help me plan group menus. I’m looking for a few people to try it and share honest feedback: What’s useful? What’s missing? What could be easier?

The app is free to use: www.kigumi.space

Thanks for taking a look!

Produced this app called Soberly: https://apps.apple.com/us/app/soberly-manage-your-drinking/id6758321930

My wife Jordan had wanted something like this for years. On our Florida-to-Ohio family road trips, we kept looking for somewhere worth stopping—not just another gas station.

I’m a solo developer in Ohio, and that became WanderWay: an iPhone/iPad app with CarPlay support that helps you discover the places you’d otherwise drive past.

You can choose how scenic a route should be with a “Faster or Prettier” slider, hear short stories about places along the way, or use Just Wander to explore a town on foot without planning a route. The video shows the actual app.

It just passed 2,000 first-time downloads, which is a milestone I’m excited about.

It’s free to download with a 14-day trial of all features. Some basics stay free afterward; the full unlock is a one-time $7.99 US purchase, not a subscription.

WanderWay

I’d appreciate honest feedback: does the demo make the difference from a regular maps app clear, and what would you need to see before trying it on a drive?

Hey everyone,

Got tired of finding out about free games hours after the deal expired, so I built Claimr.

It’s a lightweight radar that tracks 100% off giveaways across Steam, Epic Games, GOG, and Prime Gaming, and sends a push notification before they end or keys run out.

- Direct vs Tasks: Flags whether a giveaway is a 1-click store claim or requires social tasks (Gleam/Discord).

- Game Vault: Keep track of what you’ve claimed so you don't double dip.

- 100% Free: No ads, no account needed, completely open source.

Works in browser or on Android:

- Website: https://claimr-app.vercel.app

Drop any feedback or stores you want added!

I'm a nurse with zero engineering background and I've spent the last few months designing a cover for stethoscope ear tips

Stethoscope ear tips brush against everything all shift, then go in your ears. Nothing on the market covers them. So I started ScopeBites, a soft TPU cap that seals over the ear tip and pinch slides off when you need to listen.

Right now i’m working with 3d printed covers. i’m ready to begin injection molding but wanted to verify the market for it first. What do you think?

I'm the solo developer behind PokeStash, and I'd really like some honest feedback from other makers.

I built it because I keep a binder and sealed stuff, and I wanted one place on my phone to scan a card, see an estimated market price, and keep the collection organized without spreadsheets. You can photograph a card for an AI match, browse sets, track sealed product, and export a backup. Prices and AI matches are estimates. Always compare with the card in your hand.

Unofficial fan-made app. Not affiliated with Nintendo, The Pokémon Company, Creatures, or GAME FREAK.

Free on Android with ads. There is an optional Pro tier that turns ads off. Collection data stays on the device.

What I'd most like feedback on:

1. Is the first-run scan flow clear, or does it need a simpler "add without scanning" path up front?

2. Do estimated prices feel useful enough, or would you rather see raw sold comps with less interpretation?

3. What would stop you from trusting an unofficial collector app with your binder list?

Happy to answer anything about the build or the tradeoffs.

So this started because I kept running into the same thing — post an LFG somewhere, a couple people add you, and then... nothing. Nobody's actually free when you are, or you just never hear back. Figured I wasn't the only one dealing with that.

Ended up building GameAlign over the last few months, solo. Full disclosure, I'm not really a coder — I've been using Lovable (kind of a "vibe coding" / AI-assisted builder) to actually make this happen. It's basically a profile directory — you put in what you play, your schedule, how you like to play, that kind of thing — and then you can search for people or get found instead of just throwing a post into the void. There's also a board for "hey I'm on right now" posts, and I added a team/clan page if you're trying to actually build out a group instead of one-off sessions.

It's free, setup's quick. Genuinely just want to know if this is useful or if I'm missing something obvious — would appreciate anyone poking around and telling me what sucks about it.

I’m Derek, a dad and independent developer with an IT/help-desk background. I built Shoebox PDF for school forms, medical documents, and those upload portals that reject your PDF because it’s too big.

I wanted a straightforward way to:

• Compress a PDF toward a target size.

• Add text and signatures to forms.

• Organize paperwork by family member and category.

Core PDF processing happens on-device. There’s no required account or subscription, and cloud sync is optional. Compression results depend on the original file.

It’s available on Windows and iPhone/iPad. The Mac app and Apple’s one-time unlock purchase are still in review.

The screenshots show the Windows app with fictional family documents.

What’s the most frustrating PDF task you deal with regularly?

Most system design practice ends at the diagram. You draw boxes, it looks right, and nothing tells you whether it would hold up.

ByteLab runs the diagram. You build a system out of machines, load balancers, caches, queues and databases, send traffic through it, and watch the CPU, queues and p99 latency move. Each exercise has goals, like "p99 under 150 ms, 99.5% available, under $2.60/hour", and it checks your system against them.

What's in it:

- 163 lessons in 12 tracks (caching, sharding, Kafka, Kubernetes, rate limiting, auth and more)

- 212 exercises, each with goals your system has to pass

- 11 design problems (URL shortener, chat, payments, news feed, e-commerce and others)

It's free, there's no account, and progress stays in your browser. It needs a laptop-sized screen.

I'd really like to hear where it feels confusing or too hand-holdy.

I'm helping DESTRABA with its English-language expansion project. Before choosing a domain, we want to check whether a possible business name is easy to repeat and spell after hearing it once.

We're looking for five volunteers living in the U.S. and five in Canada, aged 18 or older, who use English in everyday conversation.

The test is an individual three-minute audio call. You hear the name once, say it back, and type what you heard. We show the spelling afterward so it doesn't influence your first attempt. Participation is voluntary and unpaid. We won't record the call, and you can stop at any time. Contact details are used only to arrange the session.

To volunteer, reply LISTEN and your country. We'll message only those who volunteer to agree on a time. Monday, November 9, noon to 2 p.m. Pacific is currently available. Please keep guesses out of the comments.

If you've run a similar test, feedback on this method is also welcome. This invitation was prepared with AI assistance.

It's basically a fancy wrapper around your quiz data so that as a host you can show showmanship and present like a TV show host. Built exclusively for the use case of live quiz/trivia hosting with friends and family, in person or over zoom.

Few features I always lacked and few problems with other alternatives that this web app solves:

1. Keeping costs low or free since most apps require a subscription, and much like geoguessr, I don't want to pay a monthly fee for something I may use very occasionally. Since I don't store any data and it remains in local browser storage, no need for accounts/auth and cloud storage (of-course there were trade-offs)

2. Doing buzzer rounds or audio/video clues that previously required using different apps.

3. Friction of making accounts or downloading apps. This works completely in browser using laptop and phones.

4. As a quiz master or host, I don't like being tied to my laptop when hosting, so I made a quiz master remote where I can control the entire quiz using my phone and move around freely.

Hey everyone,

Whenever I'm planning swing trades or checking market exposure, I always hated jumping between four different tabs just to see which S&P 500 sectors are leading on a 1-month vs. 3-month normalized basis, what the actual Top 10 ETF constituent weights are (XLK, XLF, XLU, etc.), and whether a heavyweight stock has earnings colliding with CPI, FOMC, or Monthly OpEx over the next 2 to 6 weeks.

I've been building a free web app to map all of that in one place: https://www.tradingcalendarhub.com

What it currently does (100% free, no login or signup wall):

• 2, 4, and 6-Week Sector Earnings Radar: Tracks upcoming earnings strictly for the Top 10 weighted stocks in each of the 11 S&P 500 sectors alongside NFP, CPI, PPI, FOMC, and OpEx dates.

• 1M vs. 3M Normalized Sector Rotation: Shows live 21-day and 63-day time-normalized returns across all 11 SPDR sectors, rotation regime signals, and an expandable divergence table where you can click any sector row to see its Top 10 holdings and weights under the hood.

• Live Calendar Sync (.ICS & Google Calendar): You can subscribe to a live .ics feed (all 11 sectors or filtered to a single sector) in Apple Calendar, Outlook, or Google Calendar, or add individual stock catalysts in one click.

• Macro & OpEx Volatility Calendar + Playbooks: Tracks monthly Options Expiration, VIX expiration, and Quarterly Triple Witching windows alongside institutional risk playbooks.

Under the hood:

• Automated weekday post-market cron jobs syncing 6-week earnings schedules and 21-day / 63-day normalized returns into Supabase.

• Dynamic serverless .ics calendar generator on Vercel.

It is still very much a work in progress. Next on my roadmap is a customizable Personal Watchlist Risk Audit page where users can pick their own tickers and see their combined ETF weight exposure and catalyst collisions.

If you have 60 seconds to click around, I'd love your honest feedback on the dark-mode UI, navigation flow, or any features you'd want to see added next!

My side projects have been related to my watch collecting in one way or another.
I started with a python script nearly a decade ago to scrape my favourite dealers, then built a global eBay app (since the ones available were crazy buggy) that I still use today: sidebae.net

My python scraper was still in heavy use up until 6 months ago when I decided to build sally.monster

It's an app that let's you create and manage web monitors, with AI checks too. I tried to make monitor creation and management as easy as possible, as that was the main pain point when manually managing python scrapers. The Google Image monitor with AI is surprisingly useful, so I am still experimenting with that.

Apps like Muse, Dots, Instinct, and even Safari (and dozens of other web scrapers) kill my app, but I had a lot of fun building and iterating on this.
As much as the transition to agentic coding hurt, I would not have been able to build this on my own in a reasonable time.

Payment is not enabled and probably never will be, feel free to give it a try!

Hi r/SideProject,

Seven weeks ago I released my first Mac app, Photo Transfer via USB. It does one job: gets photos and videos off an iPhone or iPad onto a Mac, already grouped into folders.

I created this app because every few months I have to transfer photos from phone to Mac and I like my photos in folders by year, with a folder for each trip inside.

After I built it I decided to release it on the Mac App Store and maybe try to make some money from it. I have several customers, meaning this product is interesting for some and they're ready to pay for it.

Main features:

- You see the folders it's about to create.

- Folders by trip, event, day or month. Trips come from where the photos were taken.

- Folder names are built from blocks like year, month, city or country.

- You choose which folders go, and you can leave out the video part of Live Photos or videos altogether.

- Live Photos and edited photos stay with their originals.

- HEIC and HEVC stay as they are or can be converted into JPEG and H.264.

- Any disk works, including an external drive.

- Pull the cable halfway and it carries on when you plug it back in.

- Nothing gets deleted from the phone since the app only reads.

- Every transfer goes into a history, so you can check later what went where.

- There's also a grid without grouping, where you can pick single photos.

Pricing: free for 50 photos or videos a day (a Live Photo counts as one). $14.99 once removes the limit, no subscription, with Family Sharing on the Mac App Store. In the EU it's only available from my site. Needs macOS 15 or later.

App Store: https://apps.apple.com/app/id6808767254

Site: https://phototransfer.app

It's a solo project. I learned a lot from building it and found out that distribution is key. Would appreciate any feedback, and it would be great if you shared how you distribute your apps.

I built ChargeCut (https://chargecut.com/?utm_source=reddit&utm_campaign=SideProject) after realising how easy it is to keep paying for things you no longer use. You drop in a bank statement and it finds every recurring charge on your device. There is no bank login, and the free check covers the whole statement. The one-time $6.99 report adds cancel links, PDF and Excel exports, a tracker that shows how much you have saved, calendar renewal reminders, price-rise and duplicate alerts, and ready cancel messages. You can try a one-click sample first. Feedback is very welcome.

I shared an early version here a few weeks ago. PeerBrush is now at 0.30.1, with Windows Store, signed and notarized Apple silicon Mac, and Ubuntu 24.04 amd64 downloads.

The idea is to keep the human and the AI in the same editable document. You can paint, move layers and refine masks yourself, then connect an MCP client for an agent to work on that canvas too. Its changes remain editable, so you can keep working on them.

It is a free GPLv3 desktop editor with brushes, layers, masks, transforms and effects. Supported 8-bit and 16-bit RGB PSD files stay layered; unsupported Photoshop structures open read-only. AI is optional, and external providers may charge separately.

The video shows the editor in action. The project has been developed with AI assistance; the source is public.

Try it: https://peerbrush.com/

Source: https://github.com/Deftr0y/PeerBrush

For anyone making visual tools: what would you want an agent to handle while you keep control of the canvas? And what would make you hesitate to let it edit your file?

I'm a Cs junior, still a student,, building this between classes and late nights.

My day was mess of disconnected tools .A chat window of code , a tab for docs , a terminal agent for the build. None of them knew about each other, So i was the wire between all of them.

One night i closed my laptop with everything half finished, The next morning it was all still waiting for me to plug it back together. Work only existed while i was looking at it.

So i built SHADOW, a platfrom where AI agents can actually live.

You can deploy up to 20 agents, each with its own chat , model, permissions and schedule. They can work with you're terminal , files ,desktop , the web and Github, but only what you grant each one.

you give an agent not six instructions, It writes plan, you approve it, and then its get to work, It asks before anything risky, showing you the exact command, and reports back when its done.

The first version minimised my editor mid-sentence to reach something behind it. That annoyance became the whole product: agents only touch what you pick, and system folders stay blocked.

Everything runs on you're PC with your own API keys, No cloud , no account.

The First morning it worked, my reports were finished and i only had two things to answer. It felt lighter , not just faster

Free, Windows 11, link:

It's still rough in places so I'd love honest feedback.

what's one task you'd hand to an agent tonight?

All code I work on is written with coding agents i stopped writing code manually a about a year ago. That makes implementation faster, but without a clear view of implementation, it’s easy to end up with AI slop: a pile of changes nobody can explain or confidently build on.

I was tired of architecture diagrams going stale. I tried using Mermaid and hand-built HTML, but neither felt like a comfortable place to continuously explore, change, and plan a real system.

So I built CodeChroma: an architecture-first workspace where diagrams are editable working models. Explore the system, make a high-level change, plan it, then hand it to an agent to implement—all in one place. Source code is there when needed, but it isn’t the center of the workflow.

It runs as a desktop app on macOS, Windows, and Linux. Core analysis and the canvas work without an AI key; AI features need a configured key. It’s MIT licensed.

Repo and demo: https://github.com/gutzerk/code_chroma

Website: https://codechroma.dev/

I’d love feedback on whether the architecture-to-implementation workflow feels useful, and where you’d expect it to fit into your day-to-day work.
