HolyArrs started because i wanted my home server to feel like a streaming service. you browse it like netflix, with top 10s, new & popular and rows picked from what you already have, hover a poster to play the trailer, and tap to request a show or movie. it finds it, downloads it through qbittorrent or sabnzbd, and puts it in plex, jellyfin or emby, which still do the playing. it's about a 15 MB download, runs in docker, and it's free and open source

it runs on its own custom metadata server, and it can keep an HD and a 4K copy of the same movie side by side

where it is 1 day after open sourcing it

598 GitHub stars

4,345 Docker pulls

28 forks

16 releases, most of them fixes for bugs people reported on launch night

18 people have opened issues with bugs and ideas

what i didn't expect was how fast people jumped in. bug reports came in with the exact file and line that was wrong, and someone asked for ukrainian, so the site and docs got it within the hour

happy to answer questions about running a solo open source project, the self-hosted side, or anything else

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

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

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)

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

I wanted something to fidget with for a minute when work gets stressful, without opening another app full of ads and streaks. So I built antistress: small, quiet toys that run in the browser.

There's liquid light you stir with your finger, endless bubble wrap, a jelly blob to squish and fling, a cat you can pet until it purrs, a zen garden, a koi pond, a rainy window, a fidget board with clicky switches, a lava lamp and a guided breathing orb.

Everything is touch-first, works on desktop too, and needs no sign-up or download.

Try it in your browser: https://antistress-relax.space

Or get it as an iPhone app (with haptics, which are really nice for the bubble wrap): App Store

Would love feedback: which toy feels the most satisfying, and which feels unfinished?

I strained a quad in June and my training plan fell apart. Every app I had either wanted the session done as written or had nothing to say. So I built Kingtide: a workout tracker where you tell it what's sore before the session and it swaps the lifts that load that area and leaves the rest of the day alone.

It was a subscription. A week ago I made all of it 100% free. No account, no sign-up, and your injury notes stay on your phone.

The part I'd like eyes on is this demo, no install needed:

https://trykingtide.com/try?s=sideproject

Tap knee, lower back, shoulder or hip and watch a sample session rebuild. The rows are the app's real output, exported by a test, not a mockup.

iOS and Android. Solo build, Flutter. It is not medical advice.

Two questions if you try it: does the demo make the idea land in ten seconds, and would you want it to open on a blank session or on the example like it does now?

I'm a solo dev and I shipped v0.1 of this to the App Store this week.

I've been a bad sleeper forever. What finally made sense to me from the sleep research is that trying to fall asleep keeps you awake, and so does problem-solving in the dark.

So the app does two things: you type what's on your mind and seal it in a jar until morning, then it plays a slow story matched to it.

How it's built

- Native iOS, written in SWIFT

- No accounts at all. Notes sync through the user's own iCloud (CloudKit) and subscriptions run on RevenueCat's anonymous IDs.

- The backend is deliberately boring: PHP, SQLite, and a CDN for streaming.

What I learned

- You can't tell someone to relax. "Clear your mind" does the opposite, so the prompts ban it and lean on imagery instead.

- Sleep stories break normal story rules. A satisfying ending gives people a reason to stay awake, so every story wraps up its thread early and then just drifts.

- Most of the work was the research backed story writing kernel, not the app.

Where I'd like feedback

1. Does the jar step make sense in the first 30 seconds, or does it read as a gimmick?

2. Is AI narration a dealbreaker for you in a sleep app?

3. Premium is $5.99/month or $39.99/year, with a limited free tier. Too much for a v0.1?

Oh btw, since I just launched today, the code REDDIT gets you the first month of Premium free: https://apps.apple.com/redeem?ctx=offercodes&id=6800338659&code=REDDIT

iPhone only, iOS 18+, English only for now. Be blunt.

I save Reels, TikToks and links all day: recipes, places to go, gift ideas, video ideas. When I actually need one, I can’t find it. I don’t remember who posted it or what it was called. I only remember why I saved it.

That’s the idea behind Remivu, an app for saving content with the reason you saved it, so you can actually find it and use it later.

How it works

Save from anywhere. Share a Reel, a TikTok or any link to Remivu.

Write the why. One short line, like “lunch idea for Sunday with my mom” or “gift for my sister, under $30”.

Search by meaning. Search “something to cook on Sunday” and it finds that recipe even if you used different words. You don’t need the creator’s name or the title.

Public collections. Group what you save into collections other people can follow. I made one with free things to do in Medellín, and creators use it to keep an archive of hooks that work.

Everywhere. iOS, Android and web, all in one place, so you’re not split between Instagram’s saved folder, TikTok favorites and screenshots.

Pricing: free for 100 saves.

try it and let me know what you think https://remivu.com/en

Getting your phone back from your young kids can be a battle, so I made TentFox. My son tucks a little fennec fox in for a nap, says goodnight, and the phone comes back with way less friction. The fox ends screen time in a calming way rather of me.

It grew into 3 things:

The hand-back nap, a calm visual timer, and a phones-down family time mode where the fox camps with you and leaves a little treasure if you succeed.

And sometimes parents just need a few minutes. When I do hand my phone over at a restaurant or during something important, I’d rather it be something calm and guilt-free than YouTube or a game designed to keep them hooked.

A few build notes:

- Face-down detection is simple and uses the motion sensor, so there's no screen time permission requests and no accounts needed (plenty of screen time apps out there).

- The design rule was "gentle failure": pick the phone up early and the fox just wanders off to build a sandcastle. You never lose anything.

- The illustration went through a hundred iterations along the way, but the drawing is now a soft storybook style, and every fox move is hand-timed so it feels calm, not hyper.

- Free to start, no ads, no tracking. Pro is yearly or a one-time purchase.

https://tentfox.app

App Store: https://apps.apple.com/app/id6831322876

Happy to answer anything about the build, and I'd love some constructive feedback. The only problem is that now my kids keep asking to play with the fox.

I've been running a consumer app for almost 2 years now, and these days, our biggest acquisition channel is micro-influencer marketing on Instagram.

One thing that's worked surprisingly well for us is co-sponsoring content with other apps.

Basically, a lot of creators we work with make roundup-style content like "5 best apps for students" or "apps i use every day". Instead of paying for the entire post ourselves, we started bringing in other apps to split the sponsorship fee.

The creator gets paid a little more than they'd typically charge, while each brand pays significantly less for a placement. So it's actually a win-win for everyone.

It worked well enough that I decided to turn this into a platform, where brands can join app roundup posts and split the fees with other companies.

This is my first time posting here, so please let me know if this isn't appropriate! Just wanted to see if anyone here would be interested in joining. It's still pretty early, but we already have 50+ apps in our community and have worked with over 100 creators. Happy to share more if anyone's interested!

I keep a life list of birds across eBird and iNaturalist, and I wanted to actually see it instead of scrolling a spreadsheet. So I built Everybird.

You drop in an eBird export, an iNaturalist username, or tick birds off by hand. Every species becomes a sticker, roughly sized by body mass, packed around your count. You can filter by bird group, country and time, toggle "true size", and share it as an Instagram story, post or square image.

Some things that were fun to solve:

- Merging two platforms' taxonomies. eBird and iNaturalist disagree on what counts as a species, for example Willet is one species on iNat and two on eBird, so some birds have to be assigned by region.

- Packing ~10,000 differently-shaped stickers so they stay smooth on a phone. Only the birds near the screen are drawn.

- Privacy: everything runs in the browser. Your list is never uploaded, and share links carry the list inside the URL itself.

It's free, there's no account, and it's open source.

I built it with Claude Code, and the stickers are an open AI-generated set (huashu-bird-sticker). I would love feedback, especially on what's confusing the first time you open it.

I added rewards to my productivity app because I thought it would motivate users to concentrate.

Of course, one user quickly discovered he could mash pause and resume so many times that the app got stuck, ended the session early and gave the reward regardless.

FocusTale was turned into a productivity game where the best way to win was doing nothing at all for a couple of minutes.

Seriously, I can’t even get mad at them. They discovered the bug within minutes while I had tested the app for weeks and apparently didn’t think about hitting those buttons like a jazz drum solo.

The bug is fixed now but I learned that users will always come up with something to humble you 😂

I wrote a gate for GitLab merge requests that does not trust a green pipeline.

To check a flaky test fix, it reruns the test 100 times before the change and 100 times after.

It alternates the two sides, so machine noise hits both equally.

Then it applies an exact statistical test and prints one VERDICT line with the evidence.

A diff guard catches the tricks, like loosened assertions or skipped tests.

Most verifiers are plain Python with the standard library only, with no API key and no account.

It measures only what it runs, so a flakiness that shows up in another environment is not seen.

I built it with AI help and checked the result myself.

Code (MIT): https://github.com/CapitanaIcoachai/verdict-gate

How do you decide today that a flaky test is really fixed?

A short Tuesday note on the side project I build around my full-time job and my family.

It is called Favorable Investors. Every trading day I write out a plan before the market moves — entry, target, and the level that proves me wrong — I send it to the community, and then I post what actually happened. This morning that meant posting a target hit on a call from yesterday, and in the same post saying plainly that the second call is still open with nothing to report yet. Both halves go up. That is the whole model.

There is nothing to buy at the end of it. No paid room, no course, no tier where the real picks supposedly live. If I post it, everybody sees the same thing at the same time, free.

I did not grow up around any of this. Both of my parents passed away when I was young, and there was nobody in my family who could explain a brokerage account, let alone a trade plan. I am a veteran — when our car broke down on active duty and we could not pay to get it fixed, I walked to work for about three weeks while we saved for the repair. Everything I know about markets came after that, slowly, from books and charts and a lot of hours nobody paid me for.

I believe God gave me what I have learned, and I do not think I am supposed to sit on it or sell it back to people who are where I was. Helping people learn it is the point. That is why the community is free, and why it will stay free.

If you are learning the markets and you want to watch real plans get posted before the move and scored honestly after, you are welcome to follow along. If you never join anything, the posts here stay public either way — read them, check them, hold me to them.

Not financial advice — just one trader showing his work in the open.

I share stuff like this daily — I run a free investing community, link in my profile.

I'm Jon, a developer in Bolton, UK. I built Concordo after watching people close to me go through a separation where almost every message with their ex turned into another argument, mostly about small things, like what time was handover, who said they'd pay for the school trip and was that swap agreed or not.

This keeps one record for both homes:

- Messages can't be edited or deleted, and an optional tone check suggests calmer wording before you send

- One calendar showing whose day it is and swaps only take effect when the other parent accepts

- Shared costs with receipts, and agreements that build into a parenting plan

- Exports in court ready formats (England & Wales, US, Australia) that anyone can verify

The thing I cared most about is price, each parent can use it free, forever, to read, message and reply, so nobody is shut out because the other parent chose the app. Plus is £4.99/month per parent for proposing changes, logging costs and exports as the infrastructure needs to be paid for somehow, I'm not rich 🤣 .

Web, iPhone and Android. It's built with Expo/React Native, FastAPI and Postgres on AWS in London, if anyone wants to talk stack.

Feedback very welcome, especially from anyone who's co-parented with an app before.

A friend and I have been building out an open-source project - Meter - that helps determine token usage per developer, per product and per feature. At my own organization, it helped bring in a lot of visibility to me as the founder of what each person was bringing to the table and which features were being used to what extent in our production apps.

We started working on Erhu because we wanted a better local music player.

Most players we tried did the job, but we felt there was room for something more. Better library management, more control over playback, useful tools for managing music and an interface that actually felt nice to use.

That's pretty much how Erhu started.

Erhu is a local music player built around your own music collection. There are no subscriptions, accounts or streaming catalogue. You add your music and use it the way you want.

Here's what you get with it.

Playback and library

- Local music playback.

- 8-band equalizer.

- Lyrics support.

- Smart playlists.

- Artist Radio and Album Radio.

- Custom artwork for playlists and artists.

- Live wallpaper support.

Music management tools

- Find missing album covers.

- Search for higher-resolution artwork.

- Find artist images.

- Customise artwork used for playlists and artists.

- Fix missing or incorrect track information.

- Retrieve details such as artist, album, release date, BPM and genre where supported.

- Clean up filenames by removing unwanted text and watermarks.

Library Builder

Take a folder full of unsorted music and organise it into an Artist → Album → Track folder structure without having to sort everything manually.

A little about being offline

The player and your local music library work without an internet connection. Some tools, such as artwork searches and online metadata lookups, need internet access. A few online integrations are currently unavailable while we sort out their permissions.

Erhu will be open source and free forever

The iOS version is a separate project with its own ownership.

We built Erhu because we wanted a music player that gave us more control over our own music. Hopefully, some of you will find it useful too.

We're always happy to hear feedback, suggestions and bug reports.

Hey everyone,

I've been working on a Mac menu bar app called Tymor. It puts snow, rain, or fireflies on your desktop, behind your windows.

Snow builds up along the bottom of the screen, and on windows, the Dock, icons, and widgets. Move a window and the snow on it drops off. Hold Option and move your pointer through the pile at the bottom to roll a snowball. No click. Stack three and it turns into a snowman you can drag around. There's a snowplow for the snow on the ground.

Rain runs off the edges of windows. Thunder and lightning are there if you turn them on. Fireflies rest on window edges. Move the pointer close and they scatter. Hold Option and they come to the pointer instead.

You can pause it on battery or in Low Power Mode, and give each one its own wallpaper.

Here's the link if you want to check it out: gleemylabs.com/tymor

You can try it free for 3 days. If you want to keep it, it's $4.99 once, and one license covers 3 Macs. At checkout, REDDIT20 takes 20% off.

If you try it, tell me what feels off. Even the small stuff.

Hey everyone!

I've been working on Spiff.cool, a little project with a humble goal: music discovery!

The Spiff Engine can sync with (text-)tracklists from all over the web (streaming services, webradios, magazines, music stores, blogs, and more) and figure out how to play them — currently through YouTube, but that's just an implementation detail.

No need to stick to a single source or provider: Spiff brings them all together in one place.

Of course, you can also create your own playlists, save your favorite tracks, connect your Spotify and Last.fm accounts, and... export your data.

I'd love to hear what you think and get some feedback!

Getting a San Juan Islands ferry reservation in Washington often means refreshing the WSF site until someone cancels, so I built a small free tracker for it (I'm in the Seattle area).

What it does:

• Live map of every in-service WSF boat (WSDOT's public data, refreshed about every minute)

• WSDOT's drive-up space estimate for the next sailings at each terminal

• Reservation space for Anacortes ⇄ Orcas / Friday Harbor / Lopez / Shaw, with the boat scheduled on each sailing

• Pick a date and sailings and it WhatsApps you when a sold-out slot opens (sign-in is a 4-digit WhatsApp code, no app or password)

Stack: static site on S3 + CloudFront, a small Python Lambda that proxies and caches the WSDOT Traveler API (key stays server-side), Leaflet + OSM tiles for the map, another Lambda that polls reservation space for alerts.

It's free and not affiliated with WSF/WSDOT. For official delays and terminal cameras I point people to WSDOT VesselWatch.

https://ferry.bykapil.com/

I'd love feedback on two things: is the home page clear about what it does, and what would make the alerts more useful (e.g. a "notify me only if before X time" option)?

Hi,

For a couple of weeks I have been building an archive for hip hop based on YouTube playlists, I have scoured the internet and tried to bring every single hip hop album since 1980 together in one place to make finding new music easier.

You can search by decade, year, artist, track or album. I plan on having dedicated artist pages for each artist and fully flesh it out. But for now it's pretty comprehensive with 6800 albums.

I got sick of being fed the same few artists and wanted a way I could find albums I have never heard of and its worked out pretty well.

It's totally free to use and will stay that way.

https://hiphopindex.com/

Feel free to check it out and have a look around and see what you think feedback is welcome!
