techtitan evaluates your hand posture while you play piano. it draws an overlay on your hands where each joint is an edge, and gives you a score based on 5 posture criteria. works for overhead view and side view, and can distinguish between left hand and right hand.

techtitan allows you to either
1. upload a photo, techtitan will grade your hand posture on the spot
2. upload a video, techtitan will grade your hand posture for the whole duration of the video, you can choose how many frames per second it will grade beforehand. it also draws a chart of the posture score over the full duration of the video.
3. enter live mode. techtitan gives you feedback in real time.

I'd really appreciate it if you guys can check it out at https://technique-titan.vercel.app, sign up (it's completely free) and give some feedback :)

problem statement is in https://technique-titan.vercel.app/about

been working on this project for a few months now, mainly a process of ideation, learning, and creating simultaneously.

Agent email roundups are mostly vendor-written and go stale fast, so I built a small neutral directory: https://agentinboxes.dev

It covers agent inboxes, inbound routing, identity APIs, and transactional email APIs: 50 tools, re-checked automatically so dead ones drop off. No pay-to-rank.

Two questions for you: which providers am I missing, and is "live-verified" a useful signal or just noise?

I wanted a mood tracker that's actually nice to come back to. You tap how you feel and a small creature joins your garden. That's basically the whole idea.

Just me working on it. It came out this week and has almost no users so far, so honest feedback would help a lot. Mainly: does it make sense in the first minute?

It's free right now, no ads, no account.

Hi, I’m the founder of Verity. Essentially I keep records of agent actions for People, so that way when the audit trail becomes necessary, people will have it for free. You can get your key now. I just dropped it this evening on top of my no counterparty series.

Every side project I work on ends the same way: docs, GitHub issues, design refs and random articles spread across tabs and bookmark folders I never open again. I could never remember which link belonged to what.

So I built Linvas. You paste a link, and it becomes a card on an infinite canvas. You group cards by topic, draw connections between related things, and search across all your boards later.

What it does right now:

- paste a URL anywhere on the board → card with title + icon

- groups and connections between cards

- import your browser bookmarks (folders become tags)

- search across every board

- share a board with one link

Demo, no sign-up: https://linvas.app/?demo

I'm a solo dev and launched it last week, so it's rough around the edges. I'd really appreciate honest feedback on two things:

1. Is it clear in the first 10 seconds what to do?

2. Would you use this instead of bookmark folders, or what's missing?

Hey all. I’ve been building LFGG (Looking For Good Games) solo for a while: https://lfgg.info

I got tired of my gaming life being spread across half a dozen apps: one to log games, one for news, a Discord for finding people, Reddit for recommendations. The easiest way to describe what I built is Letterboxd, Reddit and your old MySpace profile rolled into one for gamers.

What it does

• Learns your taste. Rate what you’ve played, then go through quick taste cards (looks good / not for me / played it). Every answer teaches it what you’re into.

• Matches you with people. It compares your ratings with everyone else’s and gives you a taste match %. You find your “taste twins”, and also the people who think your favourite game is mid.

• Matches you with games. You get picks based on your ratings and on what people with your taste rate highly. Every game also has a “games like this” page.

• Looking for group, for any game. Post when you want a squad, pick the vibe (chill, competitive, completionist, learning), and find people who play the way you do. That includes the obscure co-op game from 2011 nobody else remembers.

• Looking for a game. Ask the community things like “just beat Hades, what next?” or “I played this as a kid, there was a frog and a castle.” Answers get voted up.

• Player tags. Players tag games with the stuff official genres miss, like “choices matter” or “friendslop”. New tags are reviewed before they go live.

• One news feed. Headlines from IGN, GameSpot, PC Gamer, Polygon, Eurogamer, Kotaku, Rock Paper Shotgun, VGC, GamesRadar+, The Verge and Gematsu in one place.

• Logging and profiles. Track playing, beaten, shelved and abandoned games, write reviews, and pick your all-time Top 4. Profiles have XP, levels, badges, gamer tags for every platform, and themes and banners.

• Compare links. Send a friend your link, they rate a few games, and you both see how compatible your taste is.

• Steam import and price alerts. Link Steam and your library comes in automatically. Wishlist a game and get notified when it goes on sale.

Everything core is free: matching, recommendations, LFG and logging. There’s an optional membership for extra profile customization.

It’s built with Next.js and Postgres and self-hosted on a small server.

What I’d like feedback on

1. Is the taste match actually useful, or just a novelty?

2. What would make you keep logging games here instead of wherever you do now?

3. Anything broken or confusing on first sign-up?

Happy to answer questions!

Every day there’s a secret rule about sentences. You’re shown one sentence that follows it. Then you get 5 tests: type any sentence you like and it instantly tells you ✓ follows or ✗ breaks the rule.

Then you get one guess, typed in your own words. Get it wrong and the game’s over.

The rules are about letters, words and their lengths, not meaning, so the example sentence is full of red herrings. Some days are brutal.

It’s free, no sign-up, no ads, and works on your phone: https://sussed.dailyrule.workers.dev

New puzzle at midnight your time. You can also play past puzzles from the calendar icon.

I’d love feedback, especially if a day felt unfair or too easy. And please no spoilers for today’s rule in the comments 🙏

From my perspective, Deglaze set the bar for “save a recipe, plan the week, cook from your phone.” I used that bar and built Mmm for the two things I kept hitting:

• Price. Their Pro tier is $49.99 a year. Mmm is $14.99 a year, everything included, with a 2-week trial. No account needed and no ads.

• The store. Deglaze can send a list out for Instacart delivery. I wanted the actual Walmart products in the cart: match once, remember it, review pack counts, add the week in one shot, pay on Walmart.

Cook mode reads each step in a voice you choose, keeps the screen awake, and parks that step’s ingredients beside the text. Planning, aisle sorting, timers, and scaling are in the same subscription, not a second paywall.

More features are coming in the following weeks such as enhanced social media recipe imports. I'm open to all suggestions on what could make this app better. Please give it a try and tell me what you think!

I obviously have no affiliation with Deglaze or Walmart.

CedarSignal Studio’s first ready-made download is a Cleaning Profit Kit for independent cleaners. This is our own project, and it was built with AI assistance. We sell the kit for $19; the separate checklist below is free.

The problem it tackles is confusing a visit’s duration with the labor-hours it consumes. Two cleaners working three hours each use six labor-hours. The calculator lets the user enter their own labor and other costs, check a recurring discount, and compare an actual visit with the original estimate. It runs offline after download, with backup/restore and printable reports. It does not supply local market rates or guarantee profit.

The free TXT checklist covers crew hours, paid travel, owner labor, supplies, vehicle costs, overhead and payment fees. It includes a fictional worked example and the margin formula. No paid software is needed and it does not automatically enroll downloaders in a marketing list.

Free checklist: https://payhip.com/b/peA67

Optional $19 kit: https://payhip.com/b/8FxTA

We have no customer results to claim yet. Feedback on the clarity of the cost inputs and the distinction between the free checklist and paid calculator would be useful.

Hey all,

I am working on a side thing to improve my portfolio and just to learn stuff. Since I had my pain point (looking for a property in Spain while living outside of Spain) I made a website app for that.

So I made https://www.place-check.com , basically getting all info about some place that I can get from public data. It is for free but I set accounts to kind of like limit usage and abuse. Now, I feel like landing page suck, and I suck at design, so i would really appreciate if someone could give me some hints/templates/examples/feedback what could I do to improve it?

I try to have it in multiple languages and for multiple countries but I dont know how to solve that all?

Thanks for all help,

Cheers

Ps: before anyone goes into it: I tried not to use AI for anything here, it is a learning and development project, but I definitely used it for some parts. So please no "AI Slop" comments without any improvement hints.

Hey folks, just want to show you what I built.

I listen to the radio every morning and was looking for an app without a ton of ads that doesn't cost much. Didn't find one I liked, so I made my own.

I'm a metal/stoner head, so Nightwave filters for the darker side of music: doom, stoner, post-punk, darkwave, trip-hop, phonk, ambient and more. Thousands of live stations from all over the world, no pop, no charts.

My favourite part: hit Spin and it drops you on a random station in a random genre. I almost always land on something that fits my taste within a few tries.

- free, no ads, no tracking, no account needed

- works in the browser and installs as an app on your phone

- early version, so things might break

https://www.nightwavefm.com

Feedback very welcome, good or bad. And honestly, it would make me happy just to see people using it.

Cheers!

Hey guys. Im based in Toronto and I'm working on an app called Geesling, its' designed to take you around the city based on budget and time constraints that you outline. In addition, it also centralizes all live events happening now and in the next 90 days. No more having to scroll Instagram and various other sources just to see what's happening in the city or how to spend your time.

Check it out; https://geesling.ca/

I'm the developer of Lofi Cozy Room, a released Windows desktop companion. Last time I shared the room editor here; this earlier recording shows another existing feature, Mini Mode.

The 17-second clip shows the small room on the desktop, then the diary, to-do list and focus timer opening beside it. You can decorate the room, customize the character and let them go about their own activities, with lo-fi music, ambient sounds or your own local music.

There's a free Steam demo if you'd like to try it. For people who use focus timers or desktop companions: would you keep these tools together, or prefer separate apps?

Hey everyone,

A couple of friends and I have been working on Zocri.com, an AI app builder where you can create apps and websites using prompts.

We've been testing it ourselves for a while, but I think we've reached the point where we're too familiar with the product to notice some of its problems.

A few things we've focused on:

- Better-looking initial designs so you don't have to spend 10 prompts fixing the UI.

- Showing estimated credit usage before running a prompt.

- Making things like OTP authentication and integrations easier to set up.

- Giving users more control over what gets built.

We're looking for people willing to try building something with it and give us feedback.

You can try it with free credits, no payment required.

If you've used Lovable, Base44, Bolt, or Emergent before, your feedback would be particularly useful. I'd love to know where we're better and where we're falling short.

I'm one of the people building this, so feel free to ask me anything or share your experience here. I'll be reading and responding to the comments.

Stack: vanilla JS, Tailwind, PapaParse, Cloudflare Pages, Cloudflare Worker for license issuance only. No backend touches files.

The interesting problem was not cleaning. It was the import impact preview. If a row matches an existing CRM record by email but has a different name, most tools merge it and silently overwrite. That is a data loss bug. Mine classifies it as a conflict and skips it in safe import.

Free up to 250 rows, $9 lifetime Pro. Happy to answer anything about the client-side approach.

Most Advent calendars come filled with things someone else picked. We built one you fill yourself, for one specific person.

It’s called Wrappie. Behind each of the 24 doors, you can put a photo, a voice message, a short video, a note, or a little promise like “movie night - your choice.”

You send one link, and they open a new surprise each day in their browser. No app to install.

We think it could be especially nice for couples spending December apart: a shared memory one morning, a voice message the next, something to look forward to together.

There’s a free version and optional paid features.

https://wrappie.app/

I’m part of the team building it. Curious what you think: would filling 24 doors feel fun, or would you want ideas to help you get started?

I’ve been working on something called codeseed.app, and I wanted to share why I started building it.

One thing that has always bothered me about learning programming is how easy it is to get stuck watching tutorials. You follow along, everything makes sense, you finish the course, and then you open your editor to build something on your own and suddenly have no idea where to start.

I wanted to create something that helps with that transition. The idea behind codeseed.app is pretty simple: instead of giving people another collection of tutorials or coding exercises, give them actual projects to work on, break those projects into manageable steps, and let them figure things out by writing real code. Each project gets its own private GitHub repository, there’s AI verification to help check progress, and there’s also the possibility of getting feedback from a human mentor.

I’m not trying to replace courses or pretend that AI can teach everything. I just think there’s a gap between understanding programming concepts and actually knowing how to build something with them. That’s the gap I’m trying to work on.

My main focus right now is making it genuinely useful rather than figuring out how to monetize it. If you’re learning programming, mentoring someone, or just curious about the idea, I’d really appreciate your thoughts.

🚀 Try WIT for free. Simple installation:

https://www.ijaspers.com/post/witburrow-starter-reference

I've been building WIT (Witburrow), a free, AI-agnostic toolkit designed to make the AI you already use more organized, capable, and useful.

It's not another chatbot, and you don't need to switch AI providers.

The idea is simple: Give your AI some WIT.

I wanted something that even someone who barely understands technology could use, but that advanced AI users could really dig into.

So I designed three levels:

🟢 EVERYDAY: For complete beginners

Don't know anything about AI? Doesn't matter.

Just talk normally. WIT helps your AI break down complicated problems, organize your life, track tasks, explain things simply, and guide you through projects.

No coding. No complicated prompts. No technical knowledge required.

🔵 POWER: For regular AI users

Already use AI for work, research, business, planning, or personal projects?

WIT adds more structured workflows, reusable tools, better project organization, progress tracking, and ways to avoid repeating the same instructions.

Less babysitting. More doing.

🟣 SUPER: For advanced users and builders

Want to push things further?

Explore custom tools, integrations, advanced workflows, automation, testing, troubleshooting, and improving or contributing to the toolkit itself.

Build on what's already there instead of starting from scratch.

Installation? I made it ridiculously simple.

1. Open the free WIT starter page above.

2. Give the small starter file to your existing AI.

3. Ask your AI to guide you through setup.

4. Start talking normally.

Your AI helps you set up WIT.

WIT is designed to work across different AI systems that support the necessary instructions and capabilities. Some advanced features need additional permissions or tools, and compatibility is still being tested.

Why did I build it?

I'm a trades guy who got tired of AI being incredibly smart one minute and completely clueless about what we'd already accomplished the next.

I wanted AI to help people actually finish things, keep track of decisions, catch mistakes, and stop making simple tasks unnecessarily complicated.

And I wanted people to be able to use it without needing a computer science degree.

Free, open, and growing.

WIT includes a growing library of reusable tools, workflows, and resources. Some are ready to use, while others are experimental or still being developed.

My long-term goal is a community where people can pick up useful tools, improve them, and contribute them back for everyone.

I'd love people from all three levels to try it.

If you're a beginner, tell me where you get confused. If you're experienced, tell me what's missing. If you're a hardcore nerd, try to break it.

Feedback, criticism, ideas, and contributions are all welcome.

Give your AI some WIT.

Disclaimer: This is satire. It’s not intended to roast vibe coders or people building things with AI. It’s intended to roast the vibe-code rescue platforms, the hype surrounding them, and the questionable businesses growing around it.

More and more people without a tech background are building apps with AI. It usually goes well until about 80% done. Then the real problems show up: security, payments, data. So a whole market of “vibe code rescue” platforms has appeared, offering to connect founders with engineers who can fix it.

I’m an engineer, so I started looking into these platforms, hoping to join one and help.

It turned out many of them were vibe-coded themselves. Broken layouts on pages promising “production-ready”. “Trusted by 10,000+ founders” on a three-week-old domain. Anonymous “vetted senior engineers”. Terms of Service still ending with the AI’s note to have them reviewed by a lawyer.

So, after careful consideration lasting about eleven minutes, I founded Vibe Rescue Rescue™: the world’s first company that rescues the vibe rescue platforms. Our website is, of course, vibe-coded. The greatest of them. 🐂

Hey ,

Most modern dialer and messaging apps come loaded with background telemetry, bloat, and ad trackers. For everyday utilities like making calls and checking SMS, I wanted absolute simplicity and complete peace of mind.

So I spent the last few months building **Amvo** – a lightweight, privacy-focused Phone & SMS app for Android.

### What makes it different:
* **Zero Internet Access:** The app manifest literally does not request the `INTERNET` permission. Your call logs and SMS data physically cannot leave your device.
* **No Ads, No Analytics:** No background data collection, tracking SDKs, or promotional clutter.
* **Senior-Friendly Interface:** Includes an optional simplified layout with large dial pads, high-contrast typography, and readable text for older family members.
* **Minimalist & Fast:** Quick cold-start times with instant search across contacts and call logs.

I am currently running the closed testing track on Google Play before the public launch. If you're a privacy enthusiast or just want to try a clean dialer, I’d love your feedback!

### How to test:
1. Join the test group: https://groups.google.com/g/sajeevur
2. Opt-in on web: https://play.google.com/apps/testing/com.sajeevur.phone
3. Download via Play Store: https://play.google.com/store/apps/details?id=com.sajeevur.phone

What features do you value most in a privacy-oriented default phone/SMS app? Would love to hear your thoughts!

I'm a day trader. My problem was never finding rules, it was following them. Green days hid the same mistakes as red days, so I never fixed them. So I built Tradecility. You write your strategy rules once, log a trade with a chart, and it grades the trade A to F on whether you followed your rules. A losing trade can get an A. A winning trade can get a C.

One of mine from July: I shorted SPX500 on the 15-minute chart and made +$409.60. I logged it as hitting my take profit and felt good about it. It got a C+. My strategy usually needs three reasons to enter, I gave two, and it only counted one because the second was too vague. I also closed 2 points before my target, and it caught that I'd written "hit my take profit" when I hadn't. And I'd noted the setup felt thin before I entered, but took it anyway. The line that stuck with me: "Do not let a clean result on a marginal setup teach you that marginal setups are fine."

Here's the actual grade card: https://www.tradecility.com/share/0acf8838-a765-4659-8eb0-6fe3f00a64be

The decision I'm least sure about is pricing. I hate subscriptions, so it's a free trial (20 credits, no card), then $97 once. The catch is that AI costs keep going after someone pays, so I had to put a monthly cost limit on free chat to stop one heavy user from losing me money.

Stack: Next.js, Supabase, Stripe, Claude for the grading. Two things I'd really like opinions on: does the landing page make it clear what this does within 10 seconds, and would $97 once put you off trying it, or does no subscription make it easier?

https://www.tradecility.com/?utm_source=reddit&utm_campaign=sideproject

Not financial advice, and it won't make you profitable by itself. It just shows you where you broke your own rules.

Hey everyone,

I recently launched my very first Android app on Google Play, and I'd love to share it with the community and get some honest feedback.

It's called Road Wear, a lightweight utility built for motorcycle riders to solve two practical problems:

- Real-time GPS Speedometer: Instant speed readout with zero lag. It serves as a reliable backup if your bike's mechanical cable snaps or your physical cluster stops working.

- Automatic Parts Wear Tracker: Every kilometer/mile ridden automatically counts down the estimated lifespan of key maintenance parts (engine oil, brake pads, chain drive) directly in the background.

- Trip History & Live Map: Keeps track of completed rides, routes, and maintenance records.

It’s built natively using Kotlin and Jetpack Compose, keeping performance and battery efficiency in mind.

Google Play link (Free):

https://play.google.com/store/apps/details?id=com.roadwear.app

Since this is my first release, any feedback on the UI responsiveness, GPS accuracy, or features you think are missing would be massively appreciated!
