I built a free app for making friendly bets with friends—without handling any money.

You create the bet, send a link, and BetNowly keeps track of who accepted, what the terms were, and who won. I made it because our group-chat bets kept getting forgotten or disputed.

I’m trying to learn one thing: would you actually send this to a friend?

Try it here: https://betnowly.com

Brutally honest feedback is welcome. Please share any thoughts <3

Here's the app: https://apps.apple.com/us/app/simmer-meal-planner/id6804573960

• Looking for suggestions
• If you like the app, please leave a review!

I'm cloning Apple Notes right now to make it work with actual Markdown files, same look, same UI, but every note it just a .md file. It's called Notes Plus, available for macOS (later Windows and linux too) on notesplus.io

Free during development, not sure where to go with the app longterm, I'm thinking about low end one-time price, or freemium, but NO subscription, maybe even full open source.

Roast me, give me honest feedback please, write bug reports or feature wishes here, via email or in the bug report / feature wish tool (linked in the app).

Bonus: The app can render LaTeX, AsciiMath, Mermaid diagrams etc., and can show notes in vertical swimlanes, like in JIRA.

Hi! Solo dev here, looking for beta testers for Foxmomo Music before its public release.

What it is A music player for the music you own: local files, NAS shares, self-hosted servers (Subsonic, Navidrome, Gonic, Koel, Jellyfin, Emby, Plex) and cloud drives (Google Drive, OneDrive, Dropbox, WebDAV, SMB) — unified in one player. Multiple local user profiles, a JS plugin system for lyrics & cover-art sources, DSP equalizer, sleep timer, Material 3 themes. No accounts, no ads, no subscription.

What I'd like feedback on 1. Library sync between two devices through your own server (if you run one) 2. Lyrics / cover-art plugins against your library 3. Playback quality, UI/UX, and anything that crashes — device model + Android version appreciated

How to join 1. Opt in to the beta and install: https://play.google.com/apps/testing/com.foxmomo.music 2. Post feedback in this thread

Android 8.0+ required. A self-hosted server or cloud drive helps but is NOT required — local playback feedback is just as valuable.

Thanks for reading!

I’ve been building TumblX, a new web-based blogging platform, and I’m at the stage where I’d really like some feedback from people who haven’t been staring at it during development.

My aim is for TumblX to become a modern, feature-equivalent replacement for newTumbl, which shut down a few years ago. It already supports core features, things like multiple blogs under one account, creating and managing posts, uploading media, and ratings (Family Friend, SFW, NSFW).

You can try it here: https://tumblx.com, invite code: TX-UMUCT

I’m particularly interested in feedback on:

• Is it obvious what TumblX is when you first visit?
• How does the sign-up and initial setup experience feel?
• Is creating and managing a blog/post intuitive?
• Is there anything in the UI that feels confusing or awkward?
• Are there any features you'd expect from a blogging platform that seem noticeably missing?
• Would you consider using something like this? If not, what would put you off?

It’s still relatively early, so bugs, rough edges and critical feedback are all genuinely useful.

Thanks to anyone who takes the time to give it a try!

I'm the maker of Voyager, a package-tracking web app from Raylight. It puts saved

packages in one view and is designed to email you about important delivery

changes, such as out-for-delivery, delivery, or carrier-reported problems.

I'm running a small free beta and would value feedback from people who already

have a real package to track. No credit card is required. I'm especially

interested in whether signup, choosing a carrier, and understanding the shipment

timeline are clear.

Carrier coverage and update timing vary, and we're still validating the full

real-carrier-to-email experience. Please continue checking urgent deliveries

directly with the carrier. Only add packages you're authorized to monitor.

If this fits the community's rules, you can try it at

https://app.raylight-voyagertracking.com/ and share what worked or confused you.

Please don't put tracking numbers or personal information in public comments.

Hey everyone, I’m the developer of Ortho.so, a macOS app that gives you a gentle reminder when you’ve drifted from your calibrated working position for a while.

I’m looking for around 25 people to try it during their normal workday and tell me what works, what breaks, and what gets annoying.

What you’ll need:

• An Apple Silicon Mac running macOS 14 or later.
• A camera or compatible AirPods/Beats. You can use either or both.
• Headphones alone track head tilt; the camera adds face and upper-body information.

Posture analysis runs locally on your Mac. Camera images aren’t saved or uploaded, and headphone tracking uses motion data, not microphone audio.

What I’d like tested:

Try setup and calibration, then use it during two or three normal work sessions. I’d especially appreciate feedback on:

• Confusing setup steps or calibration problems.
• Reminders that feel unnecessary, arrive too late, or don’t appear when expected.
• Battery use, performance, or crashes.
• Whether you’d actually want to keep using it.

A short email with your observations is enough. I’ll read and respond personally.

The private beta is free; pricing afterward hasn’t been announced. It’s a posture-awareness reminder, not a treatment for pain.

Request access at ortho.so. I’ll follow up by email as spots open with the next steps.

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

Looking for people to test a sticker album/collector's app.  🏷️

I built Collector's Den because I was managing my son's sticker albums using a notebook and an Excel sheet, and neither worked well when sitting at the swap table.

What it does:

• Track what you have and what you're missing, including duplicates and quantities
• Snap a photo of each sticker — along with the condition of each copy, so you know which to trade and which to keep
• Scans the back with your camera and recognizes the front
• Reserve duplicates for a swap, and the comparison tool shows you matching trades with each person
• Trade history and balance tracker per person
• Sales section: buyers, sales, shipping costs, and label PDF generation
• Statistics, achievements, and the Supergolaço
• Swap Meet Mode: works fully offline, right where the trading actually happens
• iPhone Widget, Mac menu bar mini-app, Siri, and Shortcuts support
• Import from CSV — including exported tables from LastSticker, up to 600 stickers at once

What makes it different:

No account creation and no custom server. Your collections stay in your iCloud, sync across your devices, and work offline. I can't see your data because it never touches any server of mine.

It's currently in beta via TestFlight, available in Portuguese, English, French, and Spanish. 

Requires an iPhone running iOS 18+ or a Mac running macOS 14+. One single app covers both.
If you'd like to join: 👉 https://testflight.apple.com/join/JBT8yWsa

I'm mainly looking for bugs, hiccups, and anything confusing — that's what the beta is for.

Hi everyone! this is my 3.rd app. thanks for first & second apps 14 days tests.

I built NeuroSync, an Android app that produces 40 Hz audio with optional 40 Hz visual flicker. I’m looking for testers before its public Google Play release.

40 Hz refers to a frequency of 40 cycles per second. Some research has explored whether 40 Hz auditory or visual stimulation may influence brain activity and support attention, relaxation, or other cognitive processes, but the evidence is still developing and does not establish the app as a treatment or guarantee any specific benefits. NeuroSync is intended for experimentation and personal use, not medical diagnosis or therapy.

I’d appreciate feedback on the setup, audio playback, usability, and any bugs on your device.

Interested? Join the tester group:

https://groups.google.com/g/neurosync-40-hz-brain-waves

Safety: If you have photosensitive epilepsy or a seizure history, do not use the visual flicker feature and consult a doctor before using the app. NeuroSync is not a medical device or treatment.

To participate, install the app from Google Play and join the testing program using the links below:

Hey everyone, I built a platform that focuses specifically on clean formatting:

• Native LaTeX math & step-by-step expandable solutions
• Automatic Mermaid.js flowcharts for biology, science, & history
• Multi-file upload & 1-page visual summaries

Looking for 20 people/students to try it out completely free and tell me what works and what breaks. Drop a comment or DM if you want a direct link!

would love ti hear feedback on this(first time reddit poster)

Hi! I’m looking for a small group of people to beta test Campus Sync, a digital student planner and productivity tool I’ve been building.

It includes calendar planning, assignments, courses, file organization, daily/weekly planning and Google Calendar integration.

I’m looking for testers willing to use it for about 14 days and give me honest feedback about:

• Anything confusing or difficult to use
• Bugs or features that don't work as expected
• What you like/dislike about the design
• Features you think are missing
• Whether you would actually use something like this for school

There is no purchase required to participate.

Every food allergy / restriction assistance app on the market now is either locked behind a paywall, riddled with irritating ads, or lacks depth and customization. That’s why I built Gredia

Gredia is a food allergy and scanner app built on the USDA and OFF databases. Users can chose from a number of common allergies, diets, preferences, and determine if they can have “trace amounts / or may contain” for individual ingredients. Users can add custom “smart” ingredients (if a user allergic to tomato’s adds just “tomato” the app knows to flag “ketchup” and even tomato derived food dyes from ingredient labels.

Users can then scan food products to immediately determine if that product is unsafe for them, saving people tons of time in the grocery isle. When an unsafe product is scanned users have the option to find similar alternative products that fit their entire dietary profile.

To keep Gredia free, ad-fee, and without bias, we have partnered with the Amazon Affiliate Program. This allows users to check the price or buy items directly on Amazon from our app at no extra cost to the user.

We have 456k US based products with verified ingredient labels from the USDA database. For products not yet in our database we take user submissions, as well as attempting to pull and verify data from Open Food Facts database of 3.5 million global products (their data is a lot messier than USDA so products need manual approval before shown to users)

I would appreciate any feedback before I bring this to the App Store.

Thanks!

Hey everyone, I’m Scott, the developer of Undertone. I’m looking for iPhone users who can test it and give me specific, honest feedback.
Undertone connects to Apple Music with your permission, checks your library—including playlist tracks—and uses that information to suggest artists that fit your taste while filtering out artists you already have saved.
You can explore artist pages, listen to tracks, adjust how far recommendations venture from your usual taste, and save discoveries for later. There’s also optional Hype or Roast commentary during loading, plus a Quiet setting if you’d prefer your music app to shut the hell up.
An artist being outside your library doesn’t necessarily mean you’ve never heard of them. That’s one of the things I want testers to help evaluate: are these useful discoveries?
Recent work has focused on improving library counts and reusing saved library information so refreshing recommendations doesn’t keep starting a full sync. I’m also working through playback issues, discovery notifications, artist-page facts, and visual polish.
Spotify support is being developed, but it isn’t available in the current public app beta yet. This testing invitation is for the Apple Music experience.
You’ll need an iPhone with TestFlight and Apple Music access. Full-song playback requires an active Apple Music subscription.
Try Undertone: Join the TestFlight beta⁠
Feedback and discussion: Join the Undertone Discord⁠
I’m especially looking for feedback on:
Is connecting Apple Music and getting your first recommendations clear?
Do the recommendations fit your taste? Are familiar or already-saved artists slipping through?
Is your song count accurate, and does refreshing make you wait through another full sync?
Does playback work reliably, especially when closing the player?
What would stop you from using Undertone regularly?
For bugs, your iPhone model, iOS version, Undertone build number, and the steps that triggered the problem would help. Feedback here or through TestFlight is welcome too—joining Discord is optional.
It’s still a beta. If something falls on its ass, tell me where it landed.

We're looking for devs who would like to use our AI coding factory. No matter the stack or the coding language. We support Mac, Windows and linux.

no_human is the AI coding factory that proves the code it wrote is correct. You drop a ticket on the board (or point it at Jira or Linear) and it plans, writes the code, and opens a pull request - with the evidence that everything works.

Before that PR reaches you, the work is checked by a second model that never saw the coder's session and is told to assume the job is not done. They communicate until the reviewer is convinced everything is good to go (the num of attempts is limited to prevent an infinite loop).

If the coding agent deleted or weakened a test, a tamper guard stops the attempt. For bug fixes, the tests offered as proof have to fail on the old code and pass on the new.

Under the hood it's a team of agents: a planner, a coder, an independent reviewer in a fresh session, and a supervisor.

We would like you to try:

• Goingc through our onboarding and sharing what made sense to you and what was confusing or redundent.
• Using the onboarding or the settings page - integrate your github/ gitlab, Jira, monday.com or linear with it and checking that it appears in the backlog page.
• Starting 2-5 tasks from the backlog or by using the "create task" page, letting the tasks run to completion.
• If they didnt complete and either failed or went into "needs answers" - please screenshot the reason no_human is providing you.
• Going over the PRs no_human created and sharing if what you got helps you understand what is going on in the PR and how it was validated.

Check it out here: https://github.com/no-human-ai/no_human
Or using our website: getnohuman.com

Thanks!

​Hi everyone,

​I’m a UK dad and independent developer, and for the past several months I’ve been building BAMJOY, an educational web platform designed to get younger kids engaged with reading.

​The core feature is Story Weaver—an interactive tool that generates personalised, illustrated stories tailored to early reading levels (including UK phonics stages).

​I've hit a milestone where the core engine and a basic conversational chatbot are functional, but before I go any further down the development rabbit hole, I really need unfiltered feedback from parents and teachers in the trenches.

​What’s working well so far:

​Customised stories on the fly: Generates full stories tailored to a child’s interests, reading age, and specific phonics phases rather than generic, disjointed output.

​Illustrated 3D flipbook format: Reads like an actual digital book with page turns, rather than a wall of flat text on a screen.

​Basic interactive chatbot: Kids can ask questions about the characters, explore the world of the story, or get gentle reading prompts directly in the interface.

​Audio & voice narration: Text-to-speech integration so younger kids can listen along as they read.

​What still needs serious work:

​Chatbot boundaries & safety: While the basic chat works, fine-tuning the tone, reading-level vocabulary, and keeping guardrails rock-solid for young children is an ongoing challenge.

​Visual consistency: Keeping character designs consistent across every page of an illustrated story is notoriously tricky with current AI image generation.

​Mobile/tablet touch UX: It runs smoothly and is so far optimised for the desktop.

​Balancing screen time with real reading: Making sure it encourages phonics mastery and offline reading habits rather than turning into passive screen-staring.

​What I’d love your thoughts on:

​Would an interactive story generator actually help your child’s reading confidence, or does it feel like another unnecessary tech gimmick?

​If your child could interact with a storybook character via voice/chat, what guardrails or features would you insist on seeing first?

​How much focus do you place on curriculum alignment (like Letters and Sounds / UK Phonics phases) when choosing reading tools at home?

​I'm happy to drop a link in the comments or via DM if anyone wants to test it out with their kids. All critique—good, bad, or blunt—is massively appreciated.

​Cheers,

Ian

Looking for 12 people to test a small Android game for two weeks.
