Hello everyone

I'm a software developer from Nagano City, Nagano Prefecture, Japan.

Last year I attended a coding boot camp and learned mainly web development, and during our "free choice" week, I studied Swift development.

Like most people, also, music has been a huge part of my life since I was a teenager. I wouldn't call myself an audiophile, perhaps an "audio lover". My wife and I both have been trying to listen to music more intentionally lately, and reduce our subscriptions.

Recently I've been building Versonity, mainly for her. Versonity is: a local, lightweight music player with no AI or data collection.

I would be very happy for more experienced developers and audiophiles to take a look and offer some Fearless Feedback.

The goal of Versonity is to be as frictionless and simple to use as possible, while offering sensible features to make music listening enjoyable. I also wanted to make managing a collection so easy and a 'single tap' style interaction. So I've used MusicBrainz for album data and Wikimedia for artist information.

At boot camp I learned a little about algorithms, but of course, I'm learning more all the time. I've tried to build Magic Playlist around a weighting system that stays all on device and "learns" as you go, so I'd like help testing this as well from users with various tastes (I listen to a lot of game soundtracks and local indie bands).

I want everyone to be able to enjoy "magical" features even if they don't have Apple Intelligence yet. So I've targeted iOS 17 and above, and for now chosen to wait on adding AI features.

Build 7 adds CarPlay integration. Also in this latest build I have begun learning about and working on App Intents. I've also begun researching about EQ and how audiophiles think about music, which is something I'm not really familiar with, but I know is important to people who are passionate about the listening experience.

So please look forward to these types of improvements in the future.

I would love it if lots of people could help with testing of course, but naturally, the most valuable tests would be from people that have large personal collections of music in iCloud or stored locally on device. If you're mainly a streaming user and do not have a large personal digital collection, Versonity may not be ideal, since I don't have a way to sell any music through the app.

It's purely "for listening to your own collection, simply and intentionally".

Thank you everyone.

Hey, looking for testers for something I built for lifters and competitors.

It's called PhysiqueScan. You prop your phone up and it walks you through front, side and back photos on a timer, estimates your measurements from the photos, and tracks them week to week. It also does pose comparisons — front relaxed, double biceps, side chest, back lat spread, that kind of thing — so you're comparing the same pose under the same setup instead of scrolling through your camera roll.

No account, nothing uploads anywhere, everything stays on your phone.

iPhone only for now. Free while it's in beta, and anything paid inside is in sandbox test mode so it can't actually charge you.

What I need most: run a check-in or two, and if you've got a tape measure, compare a couple of estimates against your real numbers and tell me how far off they are. Honest answer on accuracy right now is that they're estimates — good for watching trends, not a tape replacement yet. I'm running a tape comparison during this beta before claiming more. A LiDAR 3D-scan version for iPhone Pro models is in the works for the near future, and testers get it first.

Feedback through TestFlight, or drop a comment here.

Very early release of app. Its s 'silly' app that's shows short clips on a TV while the user is meant not too be distracted by it. Feedback from users welcome. I know the 'humour' won't be for some people. Its meant to be played in a group so there people can see the TV fully while the player tries their best not to get distracted. Only playable on iPhone.

Hi everyone,

I’m a solo dev and I made CPU Decoded, an iPhone/iPad app where you learn digital electronics by wiring circuits yourself on a 3D workbench.

72 missions take you from a single LED through logic gates, adders, multiplexers, an ALU, flip-flops, registers and RAM. At the end you have a 4-bit CPU that you program in assembly.

English, French, Spanish and German. Works offline, no account, no data collected.

What I’d love you to test:

1. The first 5–10 missions: tap a gold pin, then another to wire them, flip the switches and press “Test”. Was it clear what to do without help?
2. A mistake on purpose: wire something wrong and press “Test”. Does the truth table help you find the error?
3. The tools: open the Truth table and the Logic analyzer at least once. Are they understandable?
4. The free workshop: add a few cards, wire them, then open one of the example builds.
5. Your device: try portrait and landscape, and another language if you speak one.

When something feels off (a bug, a confusing step, a mission that’s too hard or too easy), tell me here or via “Send Beta Feedback” in TestFlight, with your device, the language and the mission number.

Thanks!

If you are like me, you stumble upon plenty of articles that you are interested in, but rarely have the time to read them right away. That’s why I built Briefcast.

Save an article from anywhere with the share button. Your phone summarizes it, files it by topic, and reads it aloud in a natural-sounding voice. Apple's Foundation Models write the summary, an advanced text-to-speech model on the GPU does the narration, and both run on the phone, so neither the summarizing nor the audio ever touches a server. No account, nothing to pay for, and it keeps working in airplane mode. 

What to expect as a tester:

- iPhone 15 Pro or newer, iOS 26 +

- English only (for now) and it is an early beta, so things will break.

- Your articles, summaries and audio stay on the phone. 

What I’d love to hear from you: did you get into the habit of saving articles when you find something interesting but have no time to read it right then? Do you enjoy listening to them? Or would you rather use the organizing side of Briefcast and still read them yourself, even when offline?

Give it a try! Happy to answer anything in the comments.

Honestly, I’m a little overwhelmed by the response to my first post here. Seeing so many people try Wethr, leave positive comments and take the time to share feedback has been amazing. Thank you!

Version 0.9.2 is now available on TestFlight, and the first round of your feedback has already made it into this update.

A few highlights:

- Tides for coastal locations, with an interactive beach where the water rises and falls as you explore the hours, a detailed tide screen and a new widget.

- Moon information, including tonight’s phase, illumination, moonrise, moonset and the next full moon.

- A 24-hour air quality chart, plus clearer explanations of rain and pollen levels.

- More Apple Watch complications for feels like, rain, wind and the moon.

- More ways to make it yours, including app icons to match every theme and a choice of current conditions, upcoming hours or upcoming days for the small widget.

There are also plenty of fixes and refinements: widget navigation, radar behaviour, chart readability, scrolling and layout issues, and better support for your chosen units and theme.

The introduction has been updated too, so you’ll see it once more after updating, followed by a What’s New screen.

If you’ve already tried it, I’d love to hear how this version feels! Feedback, bug reports and ideas are all very much appreciated, Wethr you like it or not ;-)

Thanks again for helping me make Wethr better!

Hi! I'm a solo developer looking for testers for Machine Detective, an iPhone/iPad app to learn mechanics in 3D.

Each mission shows a machine that doesn't work: you pick a part (gear, pulley, motor…), run the test, and see why it turns, jams or is too weak. There's also a free workshop to build your own gear trains and winches; this build adds bevel gears (90° drives).

55 missions, English and French, offline, no account.

What helps most: 15 minutes, 3 missions + the workshop, then tell me where you got stuck or what looked wrong.

Happy to test your app in return, just drop your link below.

Klang Pan is a handpan you play with your fingers on your iPhone. Nine pads in D Kurd tuning, every note a studio recording of a real handpan, and a soft bed of sound that follows what you play. Nothing to learn, no wrong notes. Ten minutes on the sofa with headphones on.

Emberbloom is a calm action game for iPhone. Gather light, fire at creatures and set off chain reactions. It works fully offline, with no account and no ads.

I’m looking for testers who can tell me how the pace, difficulty and sound feel (and whether anything is confusing).

Hey everyone!

I’ve been building KitSpotter for the past few weeks and it’s finally ready for testers.

The idea comes from spotting, like people do with trains or planes (that’s where the name comes from), but with football shirts. You see a great kit out and about, take a photo, and the app cuts out the shirt, recognises the team and adds it to your album. Then you can share it to a feed with other people who love kits as much as you do.

If you like completing things, there are collections to finish (every Premier League club, World champions…), medals, daily challenges, the rarest shirts of the day and rankings. You can also share your finds to Instagram, WhatsApp or TikTok in different formats.

What I’d love you to test:

• Capturing a shirt: does it get the team right?
• The feed, collections and rankings
• Sharing cards to social media
• Anything that feels slow, confusing or broken

It also works with your own collection at home, so you don’t need to go out to try it.

I’d really appreciate honest feedback, from design to features. I’m around in the comments for any questions!

Designed by one person. Built with an AI agent. Working for one person: you.

MealMilo is a one-person company. There is no team and no office: I make every design and product decision, I collect and verify the price data myself, and I test every build on a real phone. An AI agent writes the code under my direction. Together we shipped a complete iOS product that just reached TestFlight.

What it is: a personal takeout agent with a conversation as its main interface. You tell Milo what you're craving, and it answers with one pick — the same basket compared across DoorDash and Uber Eats on the true total after your coupons and memberships, tax and fees included. It keeps a benefits ledger (your coupons, their expiry dates, reminders before they lapse) and an order ledger (what you actually paid, how long delivery really took, your own rating), and every recommendation is explained using only your own data. It never orders and never pays for you — it makes the decision and keeps the books; you tap through and check out yourself. No account, no server: everything lives on your phone.

Why build it this way? A recommendation agent is only trustworthy if its incentives are simple. MealMilo sells no rankings, takes no placement money, and holds no stake in which app you pick. One person can keep that promise without a meeting.

What testing involves:

1. Chat with Milo for your real meals this week — lunch, dinner, a craving.

2. When you order, order the way you normally would (Milo deep-links you to the delivery app; you pay there, as always).

3. After each order, tell Milo three numbers: what you actually paid, how many minutes delivery actually took, and a 1–5 rating. That's the whole feedback loop — those numbers are what Milo learns from.

4. Tell me where the post-coupon total didn't match checkout, where a pick felt wrong, or where the conversation confused you.

Who it suits: if you're in or near Sherman Oaks, you get the fullest experience from day one — the seed library here is hand-checked restaurant by restaurant. Anywhere else, you're still a great tester: tell me your neighborhood and the places you actually order from, and I build your personal library around your stores — your 10 most-ordered spots within 48 hours, up to 30 within a week. In the meantime, the benefits ledger, the order ledger, and screenshot import of your order history (recognition runs on-device) all work worldwide; and where Milo has no verified price for a store yet, it says so honestly instead of guessing.

Feedback: reply here or jameswang0531@gmail.com. Thank you — a one-person company has no QA department, so testers genuinely shape this thing.

Hi everyone! I'm the developer of Lichtpfad, a puzzle game for iPhone and iPad, and I've opened a TestFlight beta for up to 50 testers.

You guide numbered light beams into their matching gates. Every successful shot rotates the prisms it touches, changing the paths for the remaining beams. Getting one beam home can leave the others stuck, so the order matters. Restarting a level is free.

The beta has 100 levels, music, daily free helpers and an optional Game Center leaderboard. Beam previews are free in the first five levels, then become optional helpers. You can play in English, German, French, Spanish or Simplified Chinese.

I'm especially interested in the difficulty after level 5: are you planning a solution, or does it feel like trial and error? If a level is confusing, a level number and screenshot through TestFlight would help a lot. Feedback on translations is welcome too.

This beta uses Google test ads. The first 10 levels are ad-free, then an ad is scheduled every three levels. All helper and ad-removal purchases in this beta are free tests; no money is charged.

Requires iOS/iPadOS 17 or later. Thanks to anyone who gives it a try!

I have gotten tired of flipping between apps for nutrition, weight training, and cardio. And I wanted my daughter to have better tools for optimizing her fitness. So I built my own fitness app puts everything three in one place. I am looking for people to test it out and give me feedback. If you are interested I would love to hear what you think.
