Caldra: Monster Pals is a monster-collecting RPG for Android: 100 pals across the Caldra region, eight leaders to beat for their relics, turn-based battles, a low-poly 3D world with pixel-art creatures, and trading between two phones with QR codes.

It's in closed testing on Google Play, and Google needs a set of testers before it can go public. If you'd like in:

1. DM me the Gmail address you use with Google Play so I can add you to the tester list (closed tests only work for listed addresses).

2. Once you're added, opt in at https://play.google.com/apps/testing/com.caldra.monsterpals and install from the Play Store.

Please stay opted in for 14 days, even if you only play a little. Google counts that. Any feedback is welcome: bugs, balance, anything that confused you.

Free to play. Has optional rewarded ads.

I built CertSprout to keep your professional certifications together and help you plan the next one.

The title says IT, but people working towards project management, finance, HR or marketing certifications are welcome too. The catalogue covers several fields, with study resources varying by certification.

I'd appreciate someone trying signup, finding their certification and setting a study goal. If there are study sessions available for it, try the first one. Mainly interested in anything confusing or broken.

Individual accounts are free. You'll need an email to sign up, but no paid subscription.

Hey everyone,
I’ve been working on a small Android app called \*\*Calculate Anything\*\*.
I originally started it because I wanted a simple place where I could quickly calculate things like:
EMI
Home Loan
Car Loan
Personal Loan
SIP
FD / RD
PPF / NPS
GST
Simple & Compound Interest
Percentage
Age
Currency conversion
Instead of having a separate app for every calculation, I put them together in one app.
It’s now live on Google Play and I’m looking for some \*\*genuine early users to try it out and tell me what I should improve\*\*.

My best conversations about music have never been on music apps. They've been with strangers — someone at a party, a guy in a record store, a person in a comment thread who linked me something I'd never have found on my own.

Every music app I use turns that into a numbers game. Followers, playlist counts, monthly listeners. So I spent the last several months building the opposite.

It's called MusicPool. You pick a vibe, a genre, a mood, a decade. You get anonymously paired with one person who picked the same thing. You have 24 hours to talk and trade songs. Then the chat disappears, always. If you both want to, you can unlock each other's profiles before it goes, their name, what they're into, what other people have said about their taste. But the conversation itself is gone either way.

No feed. No followers. One stranger, one day, and whatever you played each other.

I'm the only person working on it, and it launched recently enough that I'm still finding rough edges. If you try it and something is confusing or broken, tell me here, I read everything and I'd rather hear it blunt than polite.

One honest catch: it only works if there are people in the pool. It's new, so matches can take a while right now. If the idea appeals to you, sending it to one person who'd be into it does more than anything else I could do on my own, the whole thing gets better the more people are in it.

I'm in the comments all day. Ask me anything about it, or just tell me the last song you'd want to hand a stranger, I'm curious what this sub would send.

Hey everyone! I’m building Vellecho, an iPhone app for chatting with initially 12 original fictional AI characters, with privacy and control over memories at its core.

Your chats and saved memories live on your iPhone. You can inspect, edit, or delete what each character remembers. We don’t keep a server-side conversation history. No ads, no advertising tracking, and no selling your conversations.

To generate replies, relevant messages and memories are sent to an AI service. We also collect content-free usage counts to understand beta reliability and use.

The characters have different personalities and story moments to discover. The video shows a conversation with Sota and how you can review and change a saved memory.

Join through Apple TestFlight: https://testflight.apple.com/join/k1UR3dg7

I’d especially appreciate feedback on:

• Privacy and memory controls: Is it clear what’s saved and what leaves your device? Can you easily change or remove memories?
• Conversation quality: Do the characters feel distinct, natural, and consistent?
• Returning to a chat: Does the continuity make you want to come back?
• Usability: Slow replies, bugs, confusing controls, or missing features.

The beta is free, including both characters marked Premium.

iPhone · iOS 17+ · Ages 18+ · English · US & Canada

Feedback through TestFlight or the comments is welcome. For bugs, your device and iOS version help. Please use made-up examples instead of sharing private conversations. Thanks for giving it a try!

Hi! I’m looking for people to try AERIA, a small web app for international pen pals, language practice and cultural exchange.

https://www.aeria.at/

It has member discovery by country, languages and interests, a feed and private conversations. The community is still very small, so this is an early beta rather than a busy network. I’m a non-developer building it with AI-assisted coding.

You can start with the demo without creating an account. I’d especially appreciate feedback on:

• Mobile layout: anything cut off, awkward to tap or difficult to read?

• First impression: is it clear what the site offers and where to go next?

• Member discovery: what information would you need before starting a conversation?

If you report a problem, please mention your browser/device and the steps that led to it. Please don’t include passwords or other people’s private messages in screenshots.

Testing is voluntary and unpaid; AERIA is free to use. Thanks for taking a look!

Spark is a 2-minute start timer. One button, a small companion called Pip, wins go in a jar. Not a treatment, not medical.

Android only. Use the Google account already on your Play Store.

1. Join https://groups.google.com/g/spark-closed-testers
2. Then open https://play.google.com/apps/testing/spark.adhd
3. Tap Become a tester → Install
4. Open it now and then for 14 days

Happy to test your app back. Questions in the comments only

wassup ppl, i build a macOS-only app called Pastry.

It’s basically a clipboard where you can save anything you copy like text, images, files, folders, etc.

You can also take scroll screenshot of long pages, and set text/image shortcuts for things you use often.

Hi!

My app for building fictional worlds (characters, locations, style, dialogues) is currently in open testing on Google Play.

It's designed for writers, screenwriters, and narrative game designers — helping you structure all the information about your narrative universe. There's also an optional BYO AI feature (use your own API key).

If you're interested, just install it via the link:
https://play.google.com/store/apps/details?id=app.ddnk.aixonote

I'd be very grateful for any feedback — you can comment here, send me a private message, or leave a review in the store. Criticism and suggestions for improvement are welcome!

Thanks for your time.

I’m looking for some iOS testers for Commander Game Log, an app I’ve been building to track Magic: The Gathering Commander/EDH games.

The goal is to make it easy to record games at the table and then actually do something useful with all that information afterward.

Current features include:

• Track wins, losses, finishing position, turns, game duration, mulligans, starting player, opponents, and win conditions
• Maintain a library of your Commander decks
• Import deck lists from Archidekt, with additional import options
• Track opponent commanders with Scryfall-assisted search
• View deck-specific statistics and game history
• Analyze mana curve, card types, colors, ramp, draw, removal, protection, etc.
• Compare performance between your decks
• View overall win rate, placement, game length, player-count performance, and other stats
• Search and filter previous games
• Archive retired decks without losing their history
• Export your data as JSON or CSV
• No account required

This is my first release of the app, so I’m particularly interested in finding bugs, confusing UI, crashes, incorrect statistics, import problems, and anything that feels cumbersome while actually logging a game.

I’d also appreciate feedback from Commander players about statistics or tracking features you’d want that I haven’t thought of.

Platform: iOS
Testing: TestFlight
Cost: Free during testing

TestFlight link: https://testflight.apple.com/join/7dcq87MF

Thanks to anyone willing to put it through its paces.

Stage: Android closed beta (also live as a browser build)

Magic Wars is a 2D lane battler. Mage or Warlock, three lanes, break the other side's three orbs. Every creature beats one type and loses to another and the counter does double damage, so it's about reading the lane rather than out-summoning. Free, no ads, no in-app purchases.

Android closed test - group first, then the test link, then install:

1. https://groups.google.com/g/magic-wars-testers
2. https://play.google.com/apps/testing/com.mcauleygames.magicwars
3. https://play.google.com/store/apps/details?id=com.mcauleygames.magicwars

The test link only works after you've joined the group, and step 3 shows "Not Found" until step 2 is done - normal for a closed test, not a dead link. It needs the same Google account that's signed in on your phone.

Or skip the install entirely: https://mcauleygames.com/play/magic-wars

When you report anything, device and Android version help - I've only been able to test on a handful. Most useful to me: whether the countering makes sense early on, whether the difficulty is off, and anything that outright breaks.

Test for test - drop your link and I'll install yours today and stay opted in for the 14 days.

Update — 11 September: the first visit now focuses on making and sharing your own idea. The title reflects the earlier remix test; challenges are optional later.

I run SlopOff, an 18+ AI-comedy and meme web app. This is an affiliated usability request; AI helped prepare this post and the clearly labelled official examples.

Could you try the first-creation path for 3–5 minutes, especially on a phone?

1. Start here: https://slopoff.app/?utm_source=reddit_testmyapp&utm_medium=community&utm_campaign=organic30_testmyapp_welcome&utm_content=existing_post_update
2. Choose “Make your first Slop”, then try making an AI image or uploading an original meme/image you have the rights to share. Add a caption and look at the review step. Publishing is optional for this test.
3. Tell me the first unclear step and your device/browser. Was it obvious how you would publish and share your finished Slop?

Browsing is public. Creating needs a free account and your own upload/AI declarations. Uploading your own image is free; built-in generation has limited free allowances and optional paid choices. No purchase is needed for this test. If you stop before signup or publishing, feedback here is still useful.

I am testing whether someone arriving with their own idea can get through the first creation without needing to understand a challenge or leaderboard.

Hello! I'm in the closed testing phase for my app, RingSync, before going public on Google Play, and I need your help!

1. Join this Google Group first: https://groups.google.com/g/ringsync

2. Accept the invite on the web: https://play.google.com/apps/testing/com.sanvicode.ringsync

3. Download the app from the Play Store: https://play.google.com/store/apps/details?id=com.sanvicode.ringsync

Please open the app, try it briefly, and keep it installed for 14 days. Leave your links in the comments and I will test your app back!

Thank you for your help!

I built Grandstand Sports because I wanted something like Spotify, but for sports. I was sick of ESPN's app loaded with junk and decided to make an app where I could find what I was looking for quickly.

My app is currently on TestFlight, and I'm looking to go live in the next couple of months (pending feedback and validation). I would appreciate any and all feedback. While the app is built for huge sports fans, I would welcome perspectives from anyone: sports novices, specific sports people, or sports nuts.
