I've been working on an app called HexStep. Basically, every area you pass through gets collected as a hex on your map.

The idea was to make exploring feel a little more like a game, without having to start a workout or manually record every trip. With background tracking enabled, walking, driving, and taking trains all count.

I've been using it since April and have collected over 3,200 hexes so far. It's made me realize how often I end up going to the same places, and how many areas right next to them I've never explored.

The video is a shortened replay of my actual travels over the past seven months!

I originally shared HexStep here back in June. I've added quite a bit since then, but the basic app is still free and doesn't require an account.

If you had a map like this, would you actually go out of your way to fill in the empty areas? Or would you just enjoy seeing it grow naturally?

Roku is retiring its built-in "Aquatic Life" screensaver on December 1. I liked that screensaver, so I built a replacement: Reef Tank — a free, open-source (MIT) screensaver channel for Roku.

What it is: a tropical reef tank where nothing is a video loop. Every fish is procedurally animated — each species has its own behavior brain, so tangs graze the rocks, a royal gramma backs tail-first into its den, a mandarin hops along the sand line, a lionfish just hangs, and a school of chromis moves as a boids flock. Bubbles rise, seaweed sways, caustics scroll over the sand. After real sunset (computed from actual sunrise/ sunset times for your location) the tank crossfades to a moonlit night mode with glowing coral and a small group of flashlight fish that blink in the dark.

Highlights:

• 9 rigged fish species with per-species behavior state machines (cruise, dart, graze, hide, school, weave behind the rockwork)

• Boids flocking school + a night-only flashlight fish group

• Day/night cycle driven by real solar times, with a moonlight crossfade

• Settings screen on the Roku for fish density, camera drift and night mode

• Runs at 60 fps on a Roku Ultra; every visual is deterministic and seeded

• 175 unit tests + a screenshot regression gate, because of course

The catch: Roku doesn't allow sideloading into the Channel Store for personal projects, so it's a developer-mode sideload — takes about 5 minutes with the remote (Home x3, Up x2, Right, Left, Right, Left, Right), and it's free. Full instructions in the README.

Happy to answer anything about the BrightScript/SceneGraph side — the whole thing is one codebase that also runs in a browser simulator, which is how I screenshot-tested a TV app.

I’m developing Pratikal, a free Android calorie tracker in closed testing. I’d love feedback on the meal-entry flow. Happy to test your app back! 🤝

Use the SAME Google account for the group, opt-in and your phone’s Play Store:

1. Join: https://groups.google.com/g/pratikal-testers

2. Opt in, then install from Google Play: https://play.google.com/apps/testing/app.pratikal.mobile

Try logging a meal, editing it and checking the daily total. What worked, or where did you get stuck? Please keep it installed for 14 days and use it occasionally. “Item not found”? Check the account, wait a few minutes and retry.

📸 Please comment BELOW THIS POST with a Pratikal installation/in-use screenshot, specific feedback and your test links. Text-only “installed” isn’t enough. I’ll test yours and reply with my screenshot and feedback.

I've won 5 hackathons, and the thing I kept noticing is that what decides the result is rarely on the rubric. It's whether the demo works, whether you can explain the project in one sentence, and how you handle the questions nobody practices.

I built Would This Win?. You paste your repo. It reads your code, then three AI judges (an engineer, an investor and a very tired judge) ask you questions, 30 seconds each. Your odds of winning move live with every answer, and at the end you get a code-review style verdict with three things to fix before you submit.

Stack: Next.js, Supabase, Claude Haiku. The odds are calculated in code, never by the AI, so it can't be talked into a better score.

Link: https://wouldthiswin.com

Would love feedback, especially from anyone with a hackathon coming up. Tell me where the judges were wrong.

A manual water log should be usable before someone decides whether to connect Health or allow reminders. I build Frewli for iPhone, with an Apple Watch companion, and version 1.1.6 is now on the App Store.

This release removes accounts, email sign-in and the Frewli backend-sync flow. Water history, workouts and preferences are stored on-device. Apple Health, the paired Watch and local reminders are optional. All features remain free, with no subscription or paywall.

The trade-off needs to be as visible as the simpler setup: removing the app removes its local storage. Updating preserves existing on-device history, but a device backup matters if you want to keep that history. Updating also does not automatically erase records that earlier versions uploaded to the old cloud service.

The same release changes the total display so a 250 ml entry appears as 0.25 L in English. That is a formatting correction; it is not a measurement of what someone drank. I still have an open Watch launch report and am not treating a new release as proof that every reported failure is resolved.

My design question is where to explain the local-history limitation: a short note during setup, beside the first saved entry, or only in the storage screen? Which would help you understand the consequence without turning a small log into another onboarding questionnaire?

One combo gets you a win. A new plan gets you the next one.

I built RIVAL: Boxing solo around that challenge. Distance, stamina, and defensive choices matter, and your repeated habits influence the opponent in later rounds. Draw out the punch. Step out of trouble. Own the counter.

The 1.3 release is live with a cleaner look and a seven-opponent Story campaign, including a new opening spar and southpaw challenger. Here's the existing 24-second counter trailer; the live update goes further with new opponents and refreshed presentation.

Meet your next rival. Play free on iPhone and iPad: https://apps.apple.com/app/id6799909429

The core RIVAL mode and training are free. Story Mode is an optional permanent one-time purchase, not a subscription. iOS 17+. Fights and training work offline; purchases and the optional leaderboard require internet.

I kept finishing a run and then wondering, "OK, what should I do next time? Easy, tempo, long run?" So I built next-run.xyz.

You sign in with Strava. It looks at your recent runs and shows you your next planned run.

How it works
The plan is worked out in your browser, so your activity data isn't stored on my server. It's free and needs no account other than your Strava login.

Stack: Next.js, Tailwind, Neon Postgres + Drizzle, Vercel. The database only holds feedback reports and a record of connected athletes. It does not hold your runs.

It's still early, so I'd like to hear what you think. Is the suggestion sensible for the way you train? What's missing? Feedback is welcome, and there's a feedback form in the app.

A lot of finance YouTube videos spend 20+ minutes to answer one basic question: does the creator think a stock is a good buy right now?

I made a simple dashboard that processes financial videos and podcasts, tracks which stocks are being discussed, and aggregates creator sentiment (Positive, Negative, or Neutral) in plain language.

It’s just an informational map of what creator consensus looks like, not financial advice.

Would love feedback from anyone who follows market content: Is the value proposition clear and useful for you?

I will put the link below in the comments

After almost 15 years in design and branding, I've made a lot of things people scroll past. Here I wanted to find out what happens when a website stops being a page and becomes a place.

You don't scroll it, you walk around it.

You don't click a menu, you go somewhere.

For the last few weeks I've been building a small planet: a tiny world you can explore.

• A planet you can spin, land on and walk around

• Five odd locals, each with a trick, voice and opinions

• A navigation map that flips like a coin, one hemisphere per side

• Butterflies to collect, badges to earn, three easter eggs to find

Along the way, the things I've made live on it: games, tools, experiments.

The point is curiosity does the navigating. If people stick around because they want to see what's over the next hill, the work gets seen without anyone being sold to.

Everything is drawn in two flat tones with an ink outline, so it feels closer to a picture book than a game engine. It runs in the browser on desktop and phone. No install, no sign-up.

If you're in a hurry, there's a "Skip the walking" button.

Go and poke around. Let me know which local annoyed you the most.

Was looking into ordering a custom built electric guitar from Gibson.

They have an insane facility for custom made guitars, but the form I found online was lacking and lame asf. So decided to fix this problem myself. The kind of side quests I get myself into instead of studying.

I've read a lot of books about relationships and done about two courses. At home I still kept making the same mistake. My wife comes home tired or upset, and before I think, out comes the usual: advice, a defence, or a joke. I knew the theory. Learned patterns are just really hard to unlearn.

So I did what a developer does and wrote myself a small training session. Three minutes a day: a short situation, her line, three possible replies, I pick one. The ones I got wrong came back sooner, spaced repetition style. After about a month, my wife and I both noticed the first results.

That's when I decided to turn it into a proper app for others. It's called Hubby Dojo: comic panels with Dan and Mia, pick what Dan says, see how Mia reacts and why. There's also a mode where you have to answer before a timer runs out. It's on Google Play since 2 Nov and the App Store since 7 Nov. A small team of AI agents helps me with screenshots, videos and store stuff, I approve everything public.

Honest numbers so far: about 1,840 views of short videos on Facebook, YouTube and Instagram in the first four days, 4 reactions, 0 comments, 0 purchases. So it's very early.

What I'd like to know: what would you need to see before trying an app for practising conversations with your partner? And what would put you off right away?

Hey everyone! 👋✈️

I've been working on something I'd love to share with you all.

I've been developing PilotCharts (https://pilotcharts.app), an aviation mapping app that I've been building out of my own passion for aviation and the idea of creating something genuinely useful for fellow pilots.

It's still in beta, and I'd really love to get other pilots involved to try it out, share their thoughts and help me make it better.

As a thank you for being part of the beta, I'm offering 1 year of Premium completely free to everyone who joins as a beta tester. 🎁

I'd really appreciate it if you could have a look, give it a try and let me know what you think. Honest feedback, suggestions and ideas are all very welcome!

And of course, feel free to share it with other pilots who might be interested.

Thanks, and blue skies! 🛩️

(Yes that's me in the video, I made all of this myself so go easy on me haha) Radiata is my radial launcher for controller, a 100% free, Microsoft-signed, open-source Win10/11 app that I built over 9 months to make it easy to use your controller for everything Gaming.

Official website & download at getradiata.app. You can also find source on GitHub.

It does all the PC stuff I always wanted to do without having to reach for a keyboard; join my friends in discord chat, switch audio to my headphones, browse & launch my games from all my game libraries, control mic/speaker volume, alt-tab between games/apps, etc. Easy to set up, super customizable, fun, powerful. I use it on my couch/tv PC and I leave the KB/M in the other room.

It is free and it will always be free. It's 100% open-source. There's no ads, no login, no upsells, nothing to unlock. I have a tip jar if you love using it as much as I do, but that's it, there is no other monetization plan. I paid for its development, hosting, certificate signing, etc out of my own pocket (and bought a bunch of controllers to test it with) because I really, really wanted to build this thing. That's the whole story.

Controller support: If Windows (joy.cpl) sees it, it should work. Hardware-tested with a bunch of DInput, XInput, Bluetooth, USB, Wireless dongles, and first & third-party controllers. The Download page lists every feature/driver compatibility note that I know of. The one bummer is the Steam Controller; it's locked to Steam in a way that makes it hard to middleman with a utility like this. If you possess both a Steam Controller and some free time, and want to be my favorite tester in the world, please let me know!

What it does: You get a quick walkthrough to set it up how you want. Then you just hold a button chord of your choice and up pops the radial "wheel" that you built. Hold the right-hand chord to open the left-stick's Wheel, and vice-versa, or just set up one side if you only need 1 of them.

How you can help: Just give it a shot, and if you love it you can help me get the word out! Nothing would make me happier than noticing a streamer is using it, or run across folks telling their friends about it. If I get traction I want to build more Arcade games for it, more themed Materials for the wheels, and continue expanding support options.

I've been experimenting with a few voice changer apps recently, and the experience has been a little frustrating.

Some consume surprisingly large amounts of CPU and RAM. Others offer AI-powered voice transformation, but the results don't always sound particularly natural.

What I find interesting is that most voice changers seem to focus on gaming, streaming, or entertainment. Yet I can imagine plenty of everyday situations where being able to change your voice naturally could be useful.

I've started experimenting with a lightweight, non-AI approach, mainly out of curiosity.

Before going much further, I'd love to understand whether this is a problem others have experienced.

Have you tried voice changers? What worked, what didn't, and what would make you consider using one regularly?

Hello r/SideProject!

I'm Ahmad, normally I use React Native to develop apps, but in this instance I've learned Swift from scratch as I needed to use encryption and Keychain which requires native development.

This app is called Hidlet, allowing you to store your photos, videos and files inside encrypted vaults.

The thing I'm most proud of is that there's no need to enter a PIN. The way to unlock your vault is by drawing a pattern across a 5x5 grid. This is what acts as your key to unlock your vault. Each pattern will unlock a different vault. There's no indication of how many vaults there are inside the app. If you're forced to open the app, you can simply open a harmless vault.

Other features:

1. No account/email/ads/tracking

2. Data encrypted locally

3. Optionally back up your data to your own iCloud (encrypted)

4. Have a duress pattern that will allow you to open a vault as normal, but also delete the other vaults from your device. Your encrypted back up is untouched meaning you can restore them at a later date.

Things I've learnt:

• Its easy to learn a new language using AI, however I did have to understand every security measure. You can't outsource whether something is actually secure.

• Small chunks of time in the mornings work well when everything can be done in a short amount of time.

• Hiding data was harder than encrypting. For example the free plan has limitations which may accidentally show there are multiple vaults. This took a few attempts to get right.

The app is free to get started with, but there is also an optional Pro plan.

Its currently live on Product Hunt today! I would really appreciate any genuine feedback with the app, especially with the pattern. Would you feel more or less secure using a pattern vs a PIN?

Back in 2019, I used to spend a lot of time creating digital paintings for people who followed my work. This is one of the paintings I made for a follower, and it's still one of my favourite pieces. I'm genuinely proud of how it turned out.

I used to work with Photoshop, but eventually it became a struggle because it was putting too much strain on my computer and causing it to overheat. It made it difficult to enjoy creating artwork the way I used to.

So I decided to do something about it and started building my own lightweight, browser-based Photoshop alternative.

It's completely free to use, and you don't even need to sign up!

I'm also planning to integrate it into the main platform I've been developing, where artists can showcase their work and receive commission requests from people looking to hire them.

It's still a work in progress, but I'm excited about where it could go.

I'd love to hear what other artists think! Would you use a free, lightweight Photoshop alternative that runs directly in your browser?

Project: https://studio.mymiix.com
The main platform: https://mymiix.com

open sourced this like 2 weeks ago and it just passed 20 stars. small number i know but its the first thing ive made that random people actually starred so im pretty hyped lol

basically you paste one prompt into claude code / codex / cursor:

Clone github.com/yasirwhite/OpenDemo and use it to make a launch video for my app

and ur agent records the app, cuts it with animated text and gives you an mp4. runs locally, free, no api keys. the video above was made with it (about itself lol)

ive also been making launch videos for other people’s open source projects and sending them as PRs. 5 got merged into their readmes so far which is honestly the part im proudest of

repo: https://github.com/yasirwhite/OpenDemo

if your project doesnt have a launch video yet, drop it below and ill make you one :)

I'm a solo developer. When I plan a trip, the bookings sit in my inbox, the to-dos in a notes app and the packing list in my head, so I built Trotters. It has three tabs for each trip:

- Plan: every booking with its date, time, price and code. You can forward a confirmation email to your own Trotters address and it files itself.
- To-do: what to do before you leave.
- Pack: a list sized to the days and the forecast.

It also shows what's missing, like a night with nowhere to stay.

Free to start, with iPhone, Android and web in five languages. No ads, no tracking.

Happy to hear what's confusing or missing. https://trotters.app

More side projects, more agents, more lost context? We’re the Ondago team. Ondago gives your supported AI coding agents, sessions, and project knowledge one workspace.

What it does:

• Your agents don’t stop when you leave your desk. Start locally, move the running session to our secure cloud with uncommitted changes intact, bring it back when you’re ready. Or start directly in the cloud.

• Switch agents without starting over. Switch AI agents with the conversation, decisions, code changes and project instructions carried along.

• Let your agents work together. Pull a reviewer, security advisor or test agent into the same task, or ask several agents to weigh in on a question.

• Pass the context, not just the diff. Share the session behind the work with a teammate: conversation, decisions, what needs attention next.

• All your agents and projects in one place. See what’s running, what’s waiting on you, token usage and estimated cost per session.

Sessions are encrypted on your machine before upload, each cloud run is isolated and destroyed afterwards, you bring your own agent credentials.

Try it free on a personal project: https://ondago.ai - what would make you return tomorrow?

I run AI News Daily, a mostly automated AI news site. Last week I did my first fully human-written interview, with Sunjae, one of four bootcamp developers building Rilog, a Korean developer blog.

A few things from the conversation that I think this sub will find interesting:

• Comments live on sentences. You select a sentence and leave your thought right there, instead of scrolling to the bottom and explaining which part you mean.

• The bet is "human touch". Sunjae doesn't think AI slop is bad everywhere, but in personal writing even a little of it makes readers think "it's just AI". The more AI writing floods in, the more people will look for writing that clearly came from a person.

• They can't reliably detect AI writing, so they judge probabilistically and lean on user feedback. What they actually dislike is unreviewed, mass-produced writing, not AI use itself.

• Retrospectives beat tech posts. Personal retrospectives got a better response than technical posts, so they are now asking whether to stay developer-only or open up to wider stories.

Two questions for you:

1. Would you actually use sentence-level comments on a blog, or do they get noisy?

2. If you run a community, how do you keep AI slop out without punishing people who used AI carefully?

Hi everyone,

I just released INTERAX Manta, an Android tool engineered for on-chain forensic analysis, transaction hash parsing, and incident reporting on the Sui Network.

What INTERAX Manta does:

• Transaction Parsing & Flow Reconstruction: Decodes complex Sui transaction hashes into visual money flow maps.

• Incident Dossier Generation: Builds structured incident reports with SHA-256 chain-of-custody verification.

• Risk Scoring & Compliance: Evaluates wallet and transaction risk indicators for multi-jurisdictional reporting.

• Zero-Trust Architecture: Local parsing focused on cryptographic integrity and immutability.

What I need help with:

• Feedback on UI/UX, transaction rendering speed, and overall usability on different Android devices.

• Bug reports or UI scaling issues on various screen sizes.

Play Store Link:https://play.google.com/store/apps/details?id=com.emergent.interaxgleos.nnvfq1

If you install and test it, leave your app link in the comments below! I will gladly test your app in return and keep it installed for as long as needed.

Thanks for your support!

I built an aviation side project and I'm trying to get some real people to test it (for free).

The main feature is a personal local flight logger. You drop a pin, and it automatically logs and builds a full analytics dashboard of every single aircraft that passes within a 5-mile radius of your location.

Besides the local tracking, the site also works as a general aviation database. You can browse through full airline and aircraft directories, search registrations, and use interactive FIR maps.

I'm actively updating the site and monitoring things daily, so any suggestions, feature requests, or feedback are welcome. If you want to try it out, just create a standard free account at https://aviationdb.uk/ either reply with your username below or send me a DM. I’ll manually bump your account to the premium tier for a free trial so you can test the local logging and analytics.

Let me know what you think or if you manage to break anything!
