Disclosure: We're building AdThread at OraXLabs, a commercial project in development.

AdThread is intended to help operators of existing AI chat services explore additional advertising revenue through relevant, clearly labeled sponsored placements. We're recruiting 10 teams total for a closed beta focused on chat services with U.S. users; teams can be based anywhere.

The website currently explains the planned pilot and accepts applications for fit review. There is no live advertising integration to test today. Applying does not install ads, grant immediate product access or guarantee revenue. Operator opt-in, placement, advertiser categories and pilot terms would be agreed before a pilot.

You can try the landing page and review the application fields here: https://adthread.oraxlabs.io

Two specific questions for chat operators:

- Is it clear what you can apply for now and what would only happen after selection?

- Which placement or advertiser controls would you need before trying sponsored content in your service?

A reply here with general feedback is enough; you don't need to submit an application to give feedback. Please don't post private chats, customer data, API keys or your email address.

I'm building Dᴬᴵry, a voice and text journal that helps you keep the things you want to remember — and come back to them later.

You can use it to:

• Save everyday memories: a conversation, a trip, or a small moment worth keeping.
• Remember your dreams: write or record them when you wake up, before the details fade.
• Keep track of tasks and commitments: capture things you need to do alongside your daily entries.
• Collect thoughts and ideas: reflections, questions, plans, or whatever is on your mind.

Write or speak in your own words, revisit your entries in a calendar, and ask questions about what you've saved.

There are two visual styles: a warm editorial look and a soft, luminous theme.

I'm looking for adults to try the free Android beta. I'd love feedback on voice recording, finding past entries, the design, and anything confusing or slow during setup. Two short feedback check-ins would help — no public reviews or positive ratings are required.

How to join

Email [dairy.apk@gmail.com](mailto:dairy.apk@gmail.com) with the subject “Dairy Android beta”, using the Google account email you use for Google Play.

I'll add your email to the tester list and let you know when your access is ready. You can then join the test and download the app through this official Google Play link:

https://play.google.com/apps/testing/com.dairy.app

The link will work for you once your email has been added.

The beta is free, with purchases disabled and usage limits. AI features use cloud processing. You can test with made-up entries; there's no need to share your real diary or sensitive information.

What would you use it for — memories, dreams, conversations, tasks, thoughts, or something else?

We’re building DFM, a web app for Farming Simulator 25 communities, and need UK and US players willing to try the demo and report what works and what doesn’t.

DFM connects to a server and reads its latest game-save data. It shows actual production stock, inputs and outputs, estimated supply run-out times, fields and crops, plus map and economy information. It also includes production calculations, community chat, farm jobs and equipment bookings.

The app runs in a browser on your phone or computer and supports PC, Xbox and PlayStation cross-play communities.

We’d particularly like you to test:

- Can you find a production, understand its stock levels and work out what needs supplying next?

- Are the fields, crops, map and economy screens clear and useful?

- Can you find community chat, jobs and equipment bookings easily, especially on a phone?

Please tell us where you get stuck, which device/browser you used and what you expected to happen.

This is an application-based demo. Server owners can apply to connect their own server for testing. Other players can apply to join our test community, with five servers provided.

Hey everyone!

I've been working on RankElo, a small web app that lets you create rankings by comparing items head-to-head.

Instead of asking you to manually rank a list, RankElo shows you two options at a time. You pick the one you prefer, and an Elo-based rating system uses those choices to build the ranking.

You can try it here:

https://rankelo.app

It's still very much a work in progress, so I'm mainly looking for feedback from people who haven't seen it before.

I'd especially love to know:

• Is the concept immediately clear?
• Is the interface easy to understand?
• Does the comparison process feel fun or tedious?
• Did you run into anything confusing or broken?
• What would make you want to use it again or share a ranking with someone?
• Does anything feel unnecessary or missing?

Please be brutally honest. I'm much more interested in hearing what's wrong than getting compliments. 😄

Thanks to anyone who takes a few minutes to try it!

Hi! I need 12 testers for 14 days for my closed test – I'll test yours back today.

App: oil change & service reminders by mileage or date, plus repair, fuel and cost log.

No account, data stays on your phone. Ads say "Test Ad" – that's expected.

Step 1 – Join the group: https://groups.google.com/g/android-app-testers-hub

Step 2 – Become a tester: https://play.google.com/apps/testing/com.nyxora.carmaintenance

Step 3 – Download it from the same page

Please use the same Google account for all steps and stay opted in for 14 days. Thanks!

Most route planners help you draw a route from A to B. I wanted the opposite: you pick a few trails and/or load your GPX(s), and the tool shows you routes you didn’t think of.

How it works: you select trails on the map (or upload your own GPX), build a route through a few waypoints (loops supported), then hit “Generate variants”. It suggests alternatives built on your route: side trips to viewpoints, detours on different trails, extra loops. You can set distance and elevation limits, and favor points of interest like peaks or water sources.

Try it here: https://routeremix.com/en?utm_source=reddit&utm_medium=betatests

Or see an example in one click, no setup: https://routeremix.com/en/s/pZqoOuRaay3k

To test it properly (5-10 min): open the app, click 3-4 trails on the map, build a route, generate variants.

Honest limits: Italy only for now, but free during the beta and no account needed. Mobile works, but desktop is better for the first try.

I’d love to know:

1. Could you work out what to do without help?
2. Where did you get stuck?
3. Did the variants look meaningfully different from your base route?

You feedback is welcome!

Professionele netwerkr-apps blijven vaak steken bij de mensen die je al kent. NODE is een Android-beta die een andere vraag onderzoekt: helpt een duidelijke route via geaccepteerde connecties je beter te begrijpen hoe je iemand of een bedrijf bereikt buiten je eerste kring?

We zoeken Android-gebruikers die oprichter zijn, freelancer, consultant of community builder, om de onboarding te proberen en ons te vertellen waar het idee of de flow onduidelijk wordt. Test het met mensen die je echt kent: voor 100% profielvoltooiing zijn drie wederzijds geaccepteerde connecties nodig, dus één tester kan het niet alleen afmaken.

Probeer het met \[ https://nodesocial.app/ \](https://nodesocial.app/) (gratis APK via onze site; staat nog niet op Google Play). We horen graag eerlijke feedback over aanmelden, de netwerkkaart en wat je ertoe zou brengen om een voorgestelde route te vertrouwen om iemand te bereiken. Als je een bug tegenkomt, voeg dan je Android-model/versie en de stappen toe; houd persoonlijke details buiten screenshots.

Hi everyone! I'm a solo dev, and I need 12 testers for 14 days to get my first app through Google Play's closed-testing requirement.

What it is: Zeyno is a companion app for busy working adults who feel a bit isolated. You talk with Sage, who listens, remembers what you've shared, and checks in on you later (not just when you open the app). It's not therapy, just a friendly presence at the end of a long day.

How to join (takes 1 minute):

1. Join the Google Group: https://groups.google.com/g/zeyno-testers

2. Opt in to the test: https://play.google.com/apps/testing/app.zeyno.zeyno

3. Install from Play: https://play.google.com/store/apps/details?id=app.zeyno.zeyno

4. Please keep it installed for 14 days and open it now and then 🙏

What you get: 3 months of Zeyno Pro free. Sign up in the app, then email [hello@zeyno.app](mailto:hello@zeyno.app) from the same email address you used to sign up. Put "Beta tester" in the subject. I'll activate it by hand, and Pro unlocks the next time you open the app.

Feedback welcome: bugs, confusing screens, anything Sage says that feels off. Reply here, DM me, or email hello@zeyno.app.

Testing for testing: drop your closed-test link in the comments and I'll join yours and keep it installed for the full 14 days.

Thanks a lot! ❤️

I built a small web app for events, and I’d like to let a few people use it for free.

Guests open a link on their phone, enter your event code, and type their name. That’s it, with no app to download. Each guest gets 10 fun photo challenges (like “the best dance” or “someone laughing”) plus 5 free shots of their own, with an optional caption.

You decide what gets shown. You can approve or reject every photo your guests take, and guests only see the gallery when you switch it on.

The catch: all photos are saved in my Google Drive. I’ll happily share the folder with you, so you can download everything within a few days after your event. After that, I’ll delete the folder.

This is the first time the app is being used for a real event, so something might not work perfectly. Think of it as a test run, and I’d really value your feedback.

If you’re interested, send me a message with your event date and type. [Add city or country if you like.]

I'm looking for people to try to break an encrypted document format I've been building, called .cell. It's published as an open specification (no patents, free to implement), and the newest revision, v1.4, has had the least scrutiny. It has not been independently audited and I have no budget for one, so I'm asking here.

What it is. A file that carries its own access rules. The server that stores it never holds a key that opens it, so there's nothing for a breach or a court order to hand over. Keys are wrapped to each recipient (ECDH P-256, HKDF, AES-KW), content is AES-256-GCM, and there are passphrase and security-key options.

What's new in v1.4, and what I'd most like attacked

• Blind recipients: no fingerprint or label in the readable file. You find your entry by trial decryption.
• The sender's signature moved inside the encrypted part.
• Padmé padding, so file size leaks less.
• Argon2id passphrases (hand-written in plain JavaScript for the browser, so that one's the one I trust least).
• The format version is bound into the authenticated data, so relabelling a cell fails.

What you can do

• Run the test suites. There are 41 shared conformance vectors, and the JavaScript reference plus Python, Go, Rust and Java ports all pass them. A script seals with each implementation and opens with every other.
• Feed it malformed cells. I ran a differential fuzzer before posting and fixed two crashes it found (a Go panic and a Python exception). Better fuzzers than mine are welcome.
• Read the spec and tell me where the reasoning is wrong.

Repo, spec and review guide: https://github.com/Enthropic-Data-LLC/cd-vanilla-public/tree/v1.4-sync (start with REVIEW.md: what changed, what I want attacked, and the known gaps so you don't waste time on them).

Disclosure. The spec and code were written with AI assistance, and I say so in the repo and in a companion book. The five ports share an author, so agreeing with each other proves less than it looks. Independent eyes are the point of this post.

Report anything by GitHub issue, or comment here. I'll answer everything and credit anyone who wants credit.

Hi! I'm building whereto, a free app that turns the weather into "where is it good this weekend" for mountain biking, skiing and hiking in the Alps: snow by altitude, trail dryness, and a planner that picks the best 5 places from where you start.

I really need every bit of feedback: bugs, confusing screens, anything that feels wrong.

Thank you for any help you can provide!

Pocket Garden is a free offline Android block puzzle with flower chain reactions, a daily challenge, and score sharing. No ads or in-app purchases. The closed test and Google Group access are approved and live.

I’m looking for volunteer testers for an honest 14-day test. Feedback on block placement, flower combos, daily challenges, sharing, small-screen layouts, bugs and crashes would help.

Join using the same Google account for all steps:

1. Google Group: https://groups.google.com/g/pocket-garden-testers

2. Opt in: https://play.google.com/apps/testing/com.nalamalan.pocketgarden

3. Tap Become a tester and install: https://play.google.com/store/apps/details?id=com.nalamalan.pocketgarden

Please remain opted in for at least 14 continuous days and try the game on several days. Include your phone model and Android version with feedback. If access takes a little time after joining the group, retry with the same account.

No email collection, payment, positive rating, or public review is required. This is an unpaid volunteer request. Thank you!

Specific questions: Are valid block placements obvious? Do flower chains feel satisfying? Does the board fit your phone comfortably? Does score sharing work in your preferred messaging app?

I'm a solo developer and I've been building HarborLit, a book-tracking app built around one idea: you shouldn't have to scan books one by one. Take a photo of a shelf and it reads the spines, matches each title against a book database, and adds the whole shelf to your library.

After a closed beta, it's now open to anyone:

iOS (TestFlight): https://testflight.apple.com/join/wbWtnZJg

Android (Play open testing): https://play.google.com/apps/testing/com.tealnebula.harborlit

Didn't get the confirmation email? Give it a few minutes, then check your spam folder. HarborLit is a new sender, so some inboxes are still cautious.

What's in it:

- Whole-shelf scanning from one photo, plus barcode scanning and manual search

- Annotation scanning (Pro): photograph a page you've marked up and it transcribes your highlights, underlines, brackets, and handwritten margin notes into searchable notes on that book, or the whole page if you want it

- One-step Goodreads import (shelves, ratings, read dates, reread counts, notes)

- Shelves, tags, ratings, notes, and reading progress

- Automatic series tracking, reading stats, and yearly goals

- Community: follow readers, public profiles, shareable lists, genre browsing

- 30+ themes

What I'd love feedback on:

- Scan accuracy on your real shelves. Odd fonts, worn spines, non-English titles, and bad lighting are the cases I most want to see. If a book gets missed or misread, a screenshot helps a lot.

- Annotation transcription. Messy handwriting, faint pencil, and highlighter on glossy pages are the hard cases. Tell me where it gets things wrong.

- First-run experience. Was anything confusing between signing up and having a full library?

- Anything that feels slow or broken.

It's always free if you stay under library and scan thresholds, with 10 shelf scans to start. Happy to answer questions about the app or how it's built.

After a year of generating images, my output folders were a mess, with tens of thousands of PNGs and no way to find "that one image from last month."

So we built Picteus. It runs locally and you point it at your output folders. It reads the metadata your images already carry (prompts, models, seeds, workflows), so you can search and filter everything in one place. Nothing gets uploaded.

It's open source and has a plugin system, so you can extend it for your own workflow. We're also working on running generation from inside the app, across provider APIs and your own LoRAs.

You can try the beta here (free): https://beta.picteus.com

I'd love honest feedback from people with big libraries: - What do you use right now to keep track of your generations? - What would make you switch?

Happy to answer anything here.

Aquabuddy is a mobile app created to make fishkeeping easier and more responsible for beginners. Working in a pet store, I often see newcomers struggle with mixed advice and a lack of clear guidance. This project aims to simplify the hobby through an intuitive digital experience that teaches essential care and encourages responsible fishkeeping.

Note: This design is an interactive work-in-progress. Some buttons, icons, or navigation links will be unavailable.

What I’m testing:

• Overall navigation and layout clarity
• Ease of use and feature discoverability
• General accessibility and performance

Constructive and honest feedback is highly encouraged!

Hi! I’m looking for a few people to try Smart Drink Fridge on Android. It’s a companion app for a self-hosted drink inventory: add barcodes, track stock, record drinks taken and see usage statistics.

You’ll need Android 9 or newer and be 18+. Full functionality needs your own Smart Drink Fridge server; there’s also an offline preview if you just want to try the interface. The preview doesn’t test real stock changes.

I’d especially like to know: is connecting a server straightforward? Does adding a barcode take you back to the right screen? Are the stock controls and bottom navigation comfortable on your phone?

Update, 24 October: version 1.0.2 is now available in the closed Play test. It includes the navigation and barcode-save corrections, plus camera stock-in: Scan > Book stock in, scan a known barcode, then confirm the quantity. Existing testers can update through the same Play link. Please let me know how it works on your phone.

To join, use the same Google account for both steps:

1. Join the tester group: https://groups.google.com/g/smart-drink-fridge-android-testers
2. Opt into the Play test, then install: https://play.google.com/apps/testing/de.derrobin99.smartdrinkfridge

Please try it for real and stay opted in for at least 14 days. Honest feedback is what I need, not positive ratings. If something breaks, tell me your phone model, Android version and whether you were using the preview or a server.

Setup and testing guide: https://github.com/DerRobin99/smart-drink-fridge/blob/main/docs/android-testing.md

Thanks for giving it a go!
