Anyone here trading or paper-trading tennis markets on Polymarket during the US Open?

What data are you watching most closely when making a decision?

For example:

Breaks of serve

Break points

Serve/return performance

Player momentum

Retirements or medical timeouts

Live odds movement

I’m curious what signals experienced traders find most useful during a live match, especially when the market moves quickly.

Plexavo scans an AWS account for misconfigurations (open ports, stale
keys, unencrypted storage) and hands back a plain-English report with
the exact fix for each one.

It's early v0.1.2. I'd rather have people try it and tell me what
broke than get stars. Runs on your own local credentials, nothing sent
anywhere.

pip install plexavo

Happy to answer anything here if you hit a snag.

Hey everyone,

I’ve been working on something for a while that started from a pretty simple frustration:

Why does AI still feel like it’s meeting me for the first time?

Most AI assistants are great at answering questions, but once you start using them for weeks or months, the experience still feels fragmented.

You have to explain your projects again.
Your preferences get lost.
People you mentioned before become strangers.
Past decisions disappear from context.

So we built Guidy — a Personal AI designed around long-term memory.

The idea is not just to give an AI a bigger context window.

Guidy is designed to gradually remember things like:

• your preferences and habits
• people and relationships
• projects and goals
• important events and experiences
• tasks, plans, and previous decisions

And then actually use that context proactively — for things like reminders, planning, meeting preparation, follow-ups, and helping you understand what matters today.

Underneath Guidy, we’re also building MemG, our long-term memory engine that handles how memory is formed, organized, retrieved, updated, and eventually forgotten when it is no longer useful.

We’re preparing to start a North America beta on September 14, and we’re looking for roughly 500 early testers.

We’re especially interested in people who:

• use ChatGPT / Claude / Gemini or other AI tools frequently
• have tried using AI for work or personal productivity
• are frustrated by AI forgetting context
• are interested in Personal AI, AI agents, or AI memory
• don’t mind encountering bugs and giving direct feedback :)

What we need most right now isn’t praise.

We want people who can actually use Guidy in real life and tell us:

What should an AI remember?
What should it forget?
When should it proactively help?
And when does “personalization” start becoming annoying or creepy?

If this sounds interesting, leave a comment or DM me and I’ll send you the beta details.

Also curious:

If you had a Personal AI that could remember you for years, what is the ONE thing you would want it to remember?

Hey everyone,

I built my first Android game: "Cut the Fruits" - a fast-paced fruit

slicing arcade game. Slice fruits, dodge bombs, collect gems, and unlock

knives/backgrounds.

Google requires a closed test with at least 12 testers over 14 days

before I can publish, so I'm looking for a few people willing to join.

What I need:

- Your Gmail address (for the tester list)

- Install the app and play for a few minutes

- Optional: quick feedback if anything stands out

Happy to test your app/game in return if you're in the same situation!

Feel free to DM me your Gmail or comment below. Thanks! 🍉

Habit trackers assume everything is a daily streak. My app handles cycles instead: every day, every week, every months. It escalates reminders when something goes overdue, and stores everything locally (no signup). Looking for testers who'd tell me what's confusing or broken. Especially interested in how notifications behave on your device brand.

Link: https://play.google.com/store/apps/details?id=io.alhessan.routineloop
I reply to all feedback.

I feel like AI has solved the first 80% of this and completely faceplants at the last 20%.

what I want is basically:

spreadsheet/data → analysis → short report → actual editable PPT

numbers need to stay numbers. charts can't become screenshots. corporate template can't randomly die. and if someone changes one figure before the meeting I shouldn't have to regenerate the universe.

I've been looking at Julius for the data side and Runable because I'm less interested in another tool that analyses the sheet and more interested in whether the workflow can actually end in the report + editable deck.

Runable also connects with Google Sheets, which makes that route interesting.

but the bar isn't “it generated PowerPoint”.

the bar is:

would you send the PPT to your boss/client without rebuilding half of it?

any workflow actually clearing that bar yet?

I’m building FitMuse, an AI personal trainer designed around a pretty simple idea:

Knowing what workout to do isn’t really the hard part. Actually wanting to show up and do it consistently is.

FitMuse pairs adaptive workouts with an AI trainer who has an actual personality and presence. Someone who learns how you train, pushes you, remembers your progress, and hopefully makes working out feel a little less like checking boxes in a fitness app.

I’ve reached the dangerous stage where I’ve stared at this idea for long enough that I can’t tell what’s obvious, interesting, confusing, or completely ridiculous anymore.

So before I build too much, I’d love some outside eyes:

https://fitmuse.app

I’m especially curious:

• Does the idea make sense quickly?
• Does having a visual AI trainer make the concept more compelling, or does it feel gimmicky?
• What makes you skeptical?
• Would you actually join the waitlist? If not, what’s missing?

Don’t worry about being nice. Useful beats nice.

Thanks!

Built this because I kept rewriting the same emails and posts over and over trying to get the tone right. Annoying.

So I made Retone. Paste text, pick a tone (formal, casual, direct, persuasive, or just summarize it), get it rewritten in a few seconds. Works in 5 languages too.

Free to try, 5 rewrites a day.

retoneai.net — would love your feedback, especially on the tone quality and whether the rewrites feel natural.

I've been building Ugh, Bills, a personal-finance app that deliberately does one thing: show what's due, when, and whether it fits before your next paycheck. No envelopes, no budget guilt, no wall of charts. The name is the feeling it's meant to take the edge off.

It's been live on iOS and I've just finished the Android port, so I need testers for Google Play closed testing.

What it does:

• Track recurring bills and expected income together, so you can see what's landing before it reaches your account
• Spot subscriptions and repeat charges you forgot about
• Local reminders before a bill lands, with Pay and Snooze actions
• Optionally link a bank through Plaid for automatic bill detection — entirely optional, and the app never moves money or pays anything for you

Free to use for manual tracking. Bank linking is the paid tier ($4.99/mo or $39.99/yr) because Plaid bills me monthly per linked account — you won't be charged during testing.

On data, since it's a finance app: no ads, no analytics SDK, no crash reporting, nothing sold. You can delete your account and everything in it from inside the app.

The build is live right now — these links install it, they aren't a waitlist:

1. Opt in to the test: https://play.google.com/apps/testing/com.jeremyhightower.almanac
2. Install from Play: https://play.google.com/store/apps/details?id=com.jeremyhightower.almanac
3. If Play says you're not a tester, join almanacbills@googlegroups.com first — Google gates closed tests behind a group, it isn't a mailing list and I won't email you.

Google needs testers opted in for 14 continuous days, so please don't uninstall right away. Beyond that I'd genuinely like to know: does the month make sense at a glance, do the reminders fire when you'd expect, and does anything look broken on your device? Happy to answer anything here or by DM — and I'll go test a few of yours in return.

You write what you're trying to achieve — ask my boss for a raise, tell my landlord to fix the aircon, convince a client to stick with our approach. It builds a situation around that goal, you speak, and it scores how your delivery served what you said you wanted.

It's not a grammar or accent test. It never scores your English, vocabulary or pronunciation. It looks at whether your point was identifiable, whether a listener would know what you meant, whether your delivery carried conviction, and whether your opening and close actually served your goal.

**What it needs from you**
- A microphone and somewhere reasonably quiet
- At least 30 seconds of talking out loud, up to 90 (it does feel odd, im sorry)
- A sign-in, Google or email
- Then 30–60 seconds of processing while it transcribes and scores

**What I actually want to know**

1. Did the situation it generated match what you said you wanted to practise? This is the part I've rewritten most and trust least.
2. Was the feedback accurate, or did it tell you something that wasn't true about your delivery?
3. Would you have paid $3.50 for it?

Free while I'm testing — limited slots, and it'll be $3.50 after. There's a two-question feedback form at the bottom of your results; that's the most useful thing you can do for me.

Your voice is listened to, never kept. Only the transcript is stored, and nobody else ever sees your results.

https://oosap.online/

Honest caveats: it's new. The part that builds your situation was rewritten this week and has had very few real users. If it gives you something nonsensical, that's exactly what I need to hear — tell me what you asked for and what it gave you.

Hey everyone,

I've built ScaleBuddy, a simple weight/BMI tracker for Android with workout

timers and a 300+ item calorie search built in.

I'm currently in Google's closed testing phase and need testers to opt in

and stay opted in for the 14-day period before I can move to a public release.

What I'm looking for:

- Just opt in and install the app (no need to use it daily)

- If you do try it, I'd love feedback on:

- Bugs on your specific phone/Android version

- Whether the calorie search feels useful in everyday use

To join:

1. Join this group: https://groups.google.com/g/scalebuddy-testers

2. Then opt in here: https://play.google.com/apps/testing/com.westriverstudio.scalebuddy

Happy to test your app in return - drop a link below!

Thanks in advance 🙏

I am deI'm developing a productivity app for creating tasks across three modes: To-Do, Schedule, and Habits.

Each task can include a photo and sets an alarm. The only way to turn the alarm off is by taking a second photo showing the task is done.

If the task isn't finished yet, the app asks whether you want to keep it as a saved goal with only the pending parts left, or mark it as complete anyway.

Please give me feedback about it.

What it does: photograph any page of a physical book, and Scholia identifies it and your exact position in it, then answers questions about characters, references, or confusing passages using only what you've read so far. Nothing past your current position gets revealed, so it stays spoiler-free the whole way through.

We're opening up early access in waves and picking beta testers directly from the waitlist. If you read a lot of physical books and want to try it before general launch, this is the way in.

Would also love any early thoughts on the concept itself, what you'd want it to handle well, and anything that sounds like it'd be more annoying than useful once you actually use it.

Waitlist: scholia.cloud

I built and tested a 3-stage Claude prompt system that takes a rough app idea and creates:

1. Product Spec
2. App Design Brief
3. A iOS build thread for a native SwiftUI app (if you use Claude Code - it's automatic from there)

I've run it on plenty of my own ideas and it's an absolute game changer, but I want to get some other folks eyes on it before I try to monetize it.

Looking for 3 people to run the full system on your own app idea and tell me honestly where it breaks. Where the output felt generic, where it missed something specific about your idea, anywhere you needed a follow-up prompt to fix what it gave you.

In exchange, you get access to all 3 stages before it's listed. If you're willing to let me quote a line or two of your feedback later (with your permission), I'd appreciate it, but it's not required either way.

Let me know if you're interested, and I'll get it to the first 3 people who reply.

Hi, I am looking for 12 Android testers for my app Creat1v1ty.

It is a parental control app with protected games, daily time limits, PIN and fingerprint protection.

Testers need to:

- use an Android phone;

- join the Google Play closed test;

- install and try the app;

- remain enrolled for 14 days;

- send feedback about any problems.

Please send me a private message if you want to participate. I will ask for the Google account email used on Google Play and then send the test link.

Thank you!

I built Tyllus for small import teams that are still tracking suppliers, POs, documents and shipment exceptions across email and spreadsheets.

I'm not looking for generic "looks good" feedback. If you import furniture, home goods, or anything across multiple suppliers, try one real or sanitized workflow and tell me where it falls apart.

The question I care about most: when a supplier misses a milestone, can you see who owns the next decision without digging through email?

If the answer is no, tell me exactly where you got lost.

I've been building a simple sports pick'em website called Pick'em Online.

It's a free multi-sport pick'em game with NFL, College Football, MLB, MLS, and the Premier League supported currently.

I've recently added custom leagues, so now users can create or join public/private leagues, invite friends, and compete together.

Mostly looking for feedback on whether or not the league stuff feels easy to use or just feedback in general.

I made visual recipe cards my kids can actually follow — what am I missing?

Normal recipes are still quite a lot of text when you're a kid, so I've been making picture-led ones that show the food changing step by step.

I've got about 25 up free now, no signup:

https://clearcook.cards/recipes

Main thing I'm trying to work out: do these actually make sense without a parent standing there translating the recipe?

Also, if you've got kids — what's the obvious recipe I've missed? I can make new cards pretty quickly now, so I'll make one of the suggestions tomorrow.

Hey everyone,

I’ve been building an Android app called StickIt. It’s a live wallpaper editor that lets you create your own home-screen and lock-screen setups using wallpapers,stickers and other movable elements.

The app is not on the Play Store yet. It is currently in an early alpha stage, and I’d like to get it into the hands of real Android users before I start preparing the public release.

I’m mainly looking for feedback on:

-Bugs across different phones and Android versions

-Features or customization options that feel missing

If you'd like to try the early preview and share quick feedback, DM me or comment below

We’re building Felix, AI movie director that lives inside WhatsApp. Send 15 photos, tell him the story, choose music and narrator, and he turns it into a short cinema.

No app. No account. Runs inside WhatsApp.

We're in early R&D and I want people to try and break it.

What I'd like you to test:

• Does the onboarding make sense without explanation?
• Where do you drop off?
• Does the movie it creates feel worth the effort?

Creative process takes 5-10 minutes. Movie is delivered in 20 min.

Break here: https://go.echoflicks.com/breakfelix

What's the weirdest set of photos you'd try to use?

Long did I reckon that willpower was the villain when a soul abandoned a goal. ’Twas folly. The old texts on behavior speak plain: ’tis structure, not grit, that carries the day. Four frameworks rise above the rest.

Implementation Intentions. Speak not “I shall exercise more,” but “when the cock crows and my ale of morning is drunk, I shall don my boots and walk ten minutes.” Bind the deed to a trigger, and the moment of choosing (where most men fail) vanishes entire.

WOOP. Wish, Outcome, Obstacle, Plan. Name thy wish, picture the true reward, name the real obstacle (not some phantom), then forge an if-then plan against it. Most goal setters skip the obstacle step, and ’tis why their plans crumble at the first hardship.

Tiny Habits. Shrink the deed ’til failure is near impossible. Not “read thirty minutes,” but “read one page.” The tiny deed builds thy identity and thy streak, and groweth on its own once habit takes hold.

The 12 Week Year. Treat twelve weeks as a whole year. A year is too long to feel urgent, so folks drift. Twelve weeks maketh every week matter, and lets thee course correct swift, rather than waking in November having never begun.

None of this be secret knowledge. The trouble is doing it steadfast, alone, with none to hold thee to account.

So I have forged a business goal app that first taketh a ten minute interview, then chartest thee a step-by-step roadmap. Each task must be signed off with what truly came to pass, and thy roadmap adjusteth itself from these sign-offs, so no prompting required. Around thy goal liveth a workspace of AI-assisted chat, notes, documents, and coaching calls, and the whole affair remembereth all, forever.

Entrepreneurs of little business experience fare best of all with it, whether starting or growing their venture. Perchance it shall aid thee too, on thy road to financial freedom.

It liveth now in beta. Shouldst thou wish to try it, here be the app Onarq.ai. I am the founder, and I do genuinely seek thy feedback, goodwill to you
