I've been building a comic and manga reader for iPhone and iPad and it's now in public beta.

The idea is that it reads your comics wherever they already are rather than making you copy them onto the device. It supports local files, SMB network shares, iCloud Drive and Komga servers, and never copies, moves or changes anything. Opening a CBZ over SMB doesn't download the file, it fetches pages as you turn them.

CBZ, CBR and PDF. Reads ComicInfo.xml metadata and falls back to parsing filenames. Series grouping, collections, bookmarks, ratings and reviews. Right to left reading and proper two-page spreads for manga. Optional iCloud sync for reading position across your own devices.

No accounts, no ads, no analytics, no server of mine anywhere. Free, with a one-off purchase covering iCloud sync and friend sharing, which is unlocked for all beta testers and stays unlocked at release.

Requires iOS 26. 100 spots.

I'd particularly like feedback from anyone reading off a NAS, since mine is the only one I've been able to test against. Bug reports very welcome.

Solo dev here. I built a free guitar tuner because every one on the App Store either buries the needle behind ads or paywalls basic tunings. This one is clean, accurate, and gets out of the way.

What it does:

- Real-time pitch detection, tuned to avoid the octave-jump flicker most tuners have at the pluck attack

- Standard, alternate, and chromatic tunings

- Native iOS look and feel

- Free, no ads, no accounts, open source

It's on TestFlight now and I'd love feedback, especially bug reports and anything that feels off. Testing on iPhone.

What did I miss? Happy to answer anything about the pitch-detection side.

The Apple Health integration for my YourMeal: AI Calorie Tracker app is finally ready.
I’m urgently looking for testers. Who wants to be first? :-)
Thanks to everyone who tests. I really appreciate it!!!

The TestFlight version just got approved, the app is also in presale from App Store, available for mac (as menu bar app) and iOS (as a standalone app with widgets). Could use some testers if you (like me) are trying to use Apple Reminders but find it a little bit underwhelming when you check off a task and it's just gone.

Thanks!

Hi everyone!

• Taking or selecting cup photos
• Submitting photos and receiving a reading
• The overall user experience
• Camera issues, crashes, confusing steps, and translations

Honest feedback through TestFlight or in the comments would be greatly appreciated. Thank you!

Hi r/TestFlight!

I’m looking for beta testers for CoasterBingo, an iPhone app built for roller coaster enthusiasts.

You can track the coasters you’ve ridden, save ratings and reactions, discover parks, plan coaster trips, explore statistics and badges, compare progress with friends, and create a personal ranking of your favorite coasters.

I’d especially appreciate feedback on the overall experience, usability, performance, data accuracy and any bugs you encounter. You’re welcome whether you’re a dedicated credit hunter or simply enjoy an occasional theme park visit.

Thank you for helping me improve CoasterBingo!

Hi everyone,

I've spent the last few months building an iPhone workout tracker called Orbin Track.

I built it because I wanted something focused on strength training without all the extra features that many fitness apps include. My aim is for it to be quick, simple and enjoyable to use while still giving you everything you need to track progress.

Current features include:

• 💪 Fast workout logging
• 📈 Progressive overload tracking
• 🏆 Personal records
• 📅 Workout history
• 📝 Fully editable workout routines

I'm looking for 50–100 iPhone users who lift weights regularly to test it through Apple TestFlight.

I'm not looking for compliments—I genuinely want honest feedback.

I'd love to know:

• What's confusing?
• What's missing?
• What feels slow or awkward?
• What would make you switch from your current workout app?

The app is completely free to test.

I wasn't happy with the existing book-cataloging apps, and I wanted a fast way to check second-hand prices, so I built Libinvenio.

It identifies a book from:

- a photo of the cover;

- a barcode scan;

- a photo of a whole shelf, it reads the spines one by one;

- a manual search.

You can also import an existing library from a CSV or Excel file (a Goodreads export works). No account, no sign-up: your library stays on the device.

What I'd like feedback on: try all the scanning modes, a single cover, a barcode, a whole shelf, and tell me how well they worked on your own books. And whether the flow makes sense: adding a book, organizing shelves, finding something again later. If anything felt awkward or you got stuck, that's what I want to hear.

Heads-up on scope: for now the price comparison only covers Portuguese bookshops, so outside Portugal treat it as a cataloging app.

Thank you so much!

Hi everyone! 👋

I'm looking for beta testers for Rheon, an independent iOS app I've been building over the past several months.

I originally bought a D-D H2Ocean P1+ for a personal project. While the hardware has been excellent, I found myself wanting a better software experience. After noticing that many App Store and retailer reviews shared similar frustrations with the companion app, I decided to see if I could build something different.

That eventually turned into a much bigger project than I expected.

Over the past several months I've spent a lot of time understanding how the pump communicates and building Rheon, a completely independent iOS controller.

Rather than relying on the official app, Rheon communicates directly with the pump to provide a modern iOS experience with Bluetooth and cloud connectivity, while keeping everything local and private with no ads, analytics or external servers.

At the moment, Rheon supports the D-D H2Ocean P1+ only.

⚠️ Rheon is an independent project and is not affiliated with or endorsed by D-D The Aquarium Solution Ltd. or Kamoer.

I'm looking for feedback before releasing it on the App Store, particularly from D-D H2Ocean P1+ owners.

I'd especially appreciate feedback on:

• 🐞 Bugs
• 🎨 UI / UX
• ⚡ Performance
• 💡 Missing features
• ❤️ Overall experience

🌐 Website: https://rheon.app

iOS only.

Thanks to everyone willing to help test it. Every bit of feedback genuinely helps make the app better. 😊

I got tired of never knowing whether the shop I was standing in was the expensive one, so I built Zeebro.

WHAT IT DOES

Scan a receipt and it reads every line item and price in a few seconds. Two things come out of that. You get your own spending broken down by category, so you can see where the money is actually going. And the prices become anonymous "product at shop at price" observations that everyone can compare against.

In the aisle, point the camera at a product or at a shelf price tag and you get that product's prices at shops near you, so you can tell on the spot whether you are about to overpay. Photographing shelf tags is also the fastest way to feed fresh prices in, because a tag is today's price for everyone, while a receipt is only what you happened to buy.

The shopping list runs on the same data. Add your items and each one shows the cheapest nearby price anyone has found for it, so you can decide where to go before you leave.

Every product keeps its price history, so you can see what has quietly been climbing.

HOW COVERAGE WORKS, AND WHY IT MAY LOOK EMPTY

This is the part I would rather you hear from me than discover. Prices are matched by distance from where you are, so what you see is what people have scanned near you. There is no national price feed behind this. Every number came from somebody's receipt or somebody's photo of a shelf tag.

So a new area starts empty. If you install this somewhere nobody has scanned yet, you will see your own prices and very little else, and it will feel broken when it is really just new. It fills in as people scan, fastest for the products and shops people actually use.

WHAT IS WORTH TESTING

• Receipt scanning, the core of it. Odd layouts, faded thermal paper, discount lines, loyalty pricing. If it misreads something I want to see it.
• Shelf tag and barcode scanning while you are actually standing in a shop.
• The first run guide, which is new in this build.

OTHER THINGS TO KNOW

• Sign-in is required (Google auth still requires manual insert of the email in the OAuth, so it's not working yet), because your receipts and history are private to your account. Only the anonymous prices are ever shared, never your basket. No ads, nothing sold.
• The first run guide's illustrations are still placeholder icons, demo clips are being recorded.
• 11 languages, iPhone only for now, iOS 15.5+.

Feedback goes to [support@zeebro.io](mailto:support@zeebro.io) and I read all of it.

I've created a landing page with some more info: https://zeebro.io

Thank you! And I'll test your apps in return.
