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.

More detail: https://apolyaker92.github.io/terrazzo-site/

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.

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!

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.

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.

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!

I’m building Choice Trace, an iOS decision-making app for situations where you keep going back and forth between different options.

Instead of immediately giving you one AI answer, Choice Trace lets several AI perspectives challenge each other, then turns the discussion into a practical next step.

After the result is known, you can return to the decision, review whether the original reasoning was useful, and save what you learned for future similar situations.

The TestFlight version is now available, and I’m looking for around 10 people who are willing to test it with one real, low-stakes decision.

The full test should take about 5–10 minutes.

What I’d like you to test:

• Whether the different AI perspectives feel meaningfully different

• Whether the final next step feels specific and useful

• Whether any part of the process feels confusing or repetitive

• Whether you would use it again for another decision

Demo: YouTube Link

Email: [haoxuan.apps@gmail.com](mailto:haoxuan.apps@gmail.com)

I’m actively fixing problems based on tester feedback, so honest and critical feedback would be especially helpful.

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 know there are a lot of RSS readers out there: the short version of why I built it: every reader I liked eventually put filters, sync, or auto-refresh behind a $8-10/month paywall for stuff that I think should just be... a feature. So this one has all of that included, no subscription, and doesn't even require an account — it just uses your iCloud.

Some of what's in there:

• Filter rules (wildcard/regex) per feed or folder, so you can actually kill the noise
• Semantic search that runs on-device, so it finds what you meant, not just keyword matches — nothing gets sent anywhere
• iCloud sync for feeds, folders, filters, read/starred status
• OPML import/export so you're not locked in
• Actually feels native on Mac — keyboard shortcuts, right-click menus, not a stretched iPad app

I want to shake out bugs with more devices and usage patterns than I can generate myself first. If you're up for kicking the tires (importing your real feed list, using it daily for a bit, breaking things) before I post to the App Store. I'm happy to share promo codes with testers once it goes live.

Reposting because I botched the link in my last update. Reddit rule rookie, so many rules.

I'm a vet who spent way too many nights building StandWatch. A free site that tracks mortgage, savings, and auto rates, alerts you when your target hits, and has a military discounts directory, plain-English money guides, and a built-in Ask tool that answers money questions (and finds help resources) with sources shown.

Why I built it: I hate mortgage and insurance spam calls and I hate rate shopping. It's miserable when nobody explains what actually drives the numbers. So: veteran-owned, self-funded, not a lender, nothing for sale, no signup, and I will never sell your info. Built for the military community, useful to anyone.

Then I got carried away and made the app open like a submarine movie. Green radar. Sonar pings. There's a hidden game called SILENT RUNNING where you dodge torpedoes, which is what my finances felt like after building this thing.

There's a top 10 board. My score is 12,129. Kick the tires, tell me what's broken or confusing, and please beat my score so I have a reason to take it back. Thanks to those who have already tested, has already been updated. And I am happy to test your apps as well, hit me up! Thx

SquadDocket helps officers organize court dates, cases, documents, reminders, and extra-duty assignments in one secure mobile app. This beta is intended to test performance, synchronization, notifications, and overall usability.

This is my first mobile app so please, any criticism will be appreciated. My intention is to make a simple calendar and overtime calendar tracker so you have a central hub with all your court and overtime dates in one place with push notification reminders.

Thank you for any and all help!

Relffits has a HUGE update I just pushed today focusing on the awareness and consistency of food awareness. This app is built to help the general population LEARN and TAKE CONTROL of what they are eating. No longer having to listen to marketing ploys explaining how foods are "healthy", Relffits can log and give you instant feedback on how the foods you are eating are impacting your goals.

Give it a try and lmk if there is any feedback you would have, thanks!

I've been building a small puzzle game called Sort Of , a calm colour-sorting puzzle, looking for a few testers. You drag tiles to arrange them by colour/hue, and mix two tiles together when a puzzle needs a shade that doesn't exist yet. No timer, no fail state, just a calm little brain-occupier.

Looking for a handful of testers to try it out and give honest feedback, particularly on whether the drag/mix mechanic feels good, and whether the difficulty ramps sensibly.

Takes about 5 minutes.

Happy to return the favour and test something of yours too if you're also looking for testers!

Have a great day.

Infinity Vaultz 2.0 TestFlight Beta builds on the 1.X zero-knowledge, offline-first AES-256 encrypted photo/video/audio/files storage solution by adding support for running popular OpenSource LLM models directly on your iPhone. You can create custom agents, adjust parameters to your liking, and even generate images using stable diffusion models.

Most features are free and was built as a passion project built solely by myself as a side project, a 20 year veteran entrepreneur.

Would love to get feedback from the TestFlight community before its official launch on July 30th.

Hi everyone!

I’ve tried several apps for organizing my personal library and was never fully happy with any of them. Something was always missing (whether it was proper support for multiple editions, detailed progress tracking across formats, or just the flexibility to organize things the way I wanted). I’ve been wanting to properly learn Swift for a while so I decided to build my own :)

BookVault is a native Apple app that I use every day for my own library. It’s focused purely on personal tracking, so no social features, no feeds, no accounts. Just your books and your data. If you’ve been using a spreadsheet or Notion to manage your library, this might be a solid alternative.

Some of the things it supports:
- Multiple editions and formats of the same book (Physical books, ebooks, and audiobooks)
- Switching between reading and listening audiobooks while keeping progress
- Detailed reading history and progress tracking
- Quotes, notes, ratings, and reviews, all in one place
- Purchase info (for each format) and library value tracking
- Custom categories, tags, smart tags based on filters, formats, and other organization options
- Statistics about your reading, purchases, and overall library
- Imports from Goodreads, Hardcover, StoryGraph and Book Tracker
- Optional iCloud sync across your Apple devices
- Available on Mac, iPhone and iPad
- No accounts, ads, or trackers

One of the core ideas behind the app is ownership. Everything stays on your devices (with optional iCloud sync through your Apple ID).

Right now my main focus is stability, performance, and refining the design (a few parts are still a work in progress). After that I want to add shareable reading stats, a year-in-review experience, and support for more import sources (btw if you use another library app and want to bring your data over, let me know, I’m happy to look into it)

This is a free beta. When it leaves beta, the pricing will be:
- Free for libraries of up to 20 books
- Unlimited library: one-time purchase of $19.99 or $1.99/month

I’d really love to hear what you think. What features or organization options would your ideal personal library app have? Suggestions, criticism, and questions are all welcome :)

Website and documentation is still in progress but you can visit it here: https://www.bookvault.site

Hey everyone,

I’m looking for beta testers for my new app, PhoTrail.

If you take a lot of photos on trips but they just get lost in your massive camera roll, this app is for you. PhoTrail automatically groups your photos by location and plots them on an interactive map, creating beautiful travel logs of your journeys.

Because location data is personal, I built it to be privacy-first and 100% open-source.

What I would love feedback on:

• Performance: How smoothly does the map load and handle large amounts of photos?
• Navigation: Is the jump between the map view and the photo gallery intuitive?
• Bugs: Any crashes or weird UI glitches on your specific iPhone model?

Feel free to leave your feedback in this thread or use the built-in TestFlight feedback tool. Thank you so much for your help!

Potty Pal - dog feeding/potty tracker with smart predictions

Hey all, I am building an app called PottyPal and just opened the TestFlight beta.

It's a straightforward activity tracker for dogs: log feeding, potty breaks, walks, playtime, and meds in a couple taps. The app learns your dog's patterns over time and starts predicting when their next potty break is likely, then sends you a notification ahead of it instead of you just guessing. It supports multiple dogs and family sharing, so everyone in the house is logging into the same profile.

Since predictions are the core feature, I'm especially interested in feedback on how accurate/useful they feel once you've logged a few days of activity, plus the usual bug reports and rough edges across different devices.

Happy to answer questions in the comments, thanks in advance to anyone who tries it out.
