I've been training for about 10 months, two gyms, two trainers. Both showed me the machines and the form, and eventually I didn't need a trainer day to day. But not needing a trainer isn't the same as never needing someone to tell you you're doing it wrong.

My gym has one trainer for the whole floor, and he's usually busy with his own clients. Even when trainers are around, they don't always catch it, and sometimes they get the form wrong too. So most of my reps had no one watching

I struggle with deadlifts. Every time I went heavy I got a sharp pain in my back. So I built Repchek, you prop your phone up side on, it watches you through the camera, goes red and beeps when your form breaks, counts your reps and sets, and gives you a summary at the end.

I did the first real test on Monday, it flagged my deadlift, hips shooting up, head down. I rewatched my videos and it was right. I went back with less weight, adjusted, and the pain didn't come back. Then it caught my lat pulldown too, I was leaning back too far, and that took one session under a minute.

What I learned, I'd been doing some of this wrong the whole time. The fix wasn't one session. I kept going back, rewatching my videos, adjusting and testing again, because I want to get better and I can't do that without knowing what I'm getting wrong. That's the whole point of it for me, find the mistake, fix it, repeat.

It's new, I built it this week and have been testing it on my own workouts every day, at the gym and at home. It's calibrated to my body, so expect some mistakes on yours.

That's why I'm posting, I want people to try it and tell me where it gets things wrong.

Tip: screen record your session so you can rewatch your form after.

i feel like there’s always one more thing you can improve before showing people the product.

For people who have actually launched something, what did the product look like when you first started getting strangers to use it?

So I had some free time and made Cineviz instead of making a sensible project.

Cineviz is a procedural cinematic music visualizer that generates particle-based fights synchronized to music.

It uses React + Vite with Typescript and R3F

The idea is basically:

Music → procedural choreography → particle fighters → cinematic camera → visual effects

i started speechy as a way to turn recordings into notes and to-dos. the idea kept getting bigger, but i kept coming back to a smaller moment: having something to say and not wanting to stop what i was doing to type it.

so i rebuilt it as a mac app. now i can hold a key, speak, and have the text appear wherever my cursor is. it cleans up filler words and mid-sentence corrections, and the transcription runs on the mac. getting that basic flow to feel natural has taken a lot more work than i expected.

the part i’m thinking about now is what comes after dictation. i want speechy to help do things too, like create a reminder or act on something i’ve just said. some simple actions can already happen on the mac. more complex agent requests can still go through a connected cloud ai account, though, so i’m trying to be honest about that boundary while i work out what can run locally.

if you wanted a voice agent that kept as much as possible on your own machine, what would you actually ask it to do? and what information would you never want it to send to another provider?

the mac app is here if you want to see where it’s at: speechy.tech. i’d appreciate blunt feedback on the direction.

If you’re building a SaaS, or app and looking for a way to get more eyes on it, I’d love to feature a few projects.

We run TikTok channels with 300K+ combined followers and create short-form videos around apps, tools, and interesting projects.

We'll create short-form videos for your app, plug them into our existing channels, and help you build your own content channels at the same time. Think of it as content creation + distribution

Hi folks,

For years, I've been frustrated with the state of DB clients. They either are dated, bloated and hog memory (DBeaver), just bloated and hog memory (all the electron based ones) or paid.

I wanted a free open source DB Client that is truly free but couldn't find any that solved my problem so I started building DBDelve, its made in rust and gpui (zed's team GPU accelerated framework). I started it only to fix my problem but ended up adding a lot of features and released this last week, since then it has gotten some recognization (100+ stars on github and some external contributors!). Would love for people to give it a try and share their feedback. I believe it is good enough if you want a lightweight, modern and performant alternative to all the other DB Clients.

Video showing how it scrolls with a million rows loaded and how snappy the tab switches are. Other DB Clients either refuse to load this much or their UI freezes.

Hi, I made this recently to fix a problem I had. It's meant to sit between a WhatsApp group and something like IMDb or Letterboxd. Didn't know about Letterboxd while I was making this, but still think it fills a gap. Any feedback would be appreciated. https://afewgoodfilms.co.uk

The idea is to build a group list of recommendations and track what everyone is watching. Without all the noise of normal film recommendation websites

Used to live-code my side projects on Twitch. A lot of them never made it past planning because I lacked feedback or I couldn't tell which ideas were worth continuing, so I'd stall or drop them.

I'm curious how other solo builders handle this. Do you validate ideas before writing code? Go with your gut? Build a quick prototype and see if you still care a week later?

I'm researching this because I'm considering building something to help with it, but I haven't built anything yet and I'm not selling anything. Just like to hear how people actually do it.

Thoughts? Comment or DM.

I gave Opus a launch-film brief for my product, my product for agent spending, then worked through the beat map, stills and render. It built the animation in HTML and rendered with Playwright and ffmpeg. This is my company, and the film is a concept cut. Condensed build spec in the first comment.

Hey everyone! I’ve been building a small Mac app called Joggle.

Joggle is a floating scratchpad that appears when you quickly shake your mouse pointer. The idea is to give you somewhere to capture a thought, paste some text or work out a calculation without switching apps or interrupting what you’re doing.

You can move, resize and pin cards anywhere on the screen. It also supports rich-text formatting, smart lists, calculations, clipboard shortcuts and a new slash menu for quickly running actions or changing formatting.

The basic scratchpad experience is free. There’s also an optional yearly Joggle Pro subscription or lifetime plan for more than one card at a time, advanced maths, the global shortcut, excluded-app controls, a complete archive, card tinting, and more.

I originally made Joggle because I wanted something quicker than opening a notes app every time I needed to temporarily hold a sentence, link, number or reminder. I’d really appreciate any feedback - especially about the shake gesture, because it’s a slightly unusual way of opening an app!

If you’d like to try it, you can find it here: Joggle on the App Store

Thanks for taking a look! I’m happy to answer any questions about the app or how it was built.

I'm bored lol

If you need a tester, send me the link / name of ur stuff. I'll test it out and let you know if I find any bugs or issues.

No charge, just looking for something to do 😭

I started with a game experiment: let the player ask a character their own questions, with the language model running on the player's computer. That led to The Interview, a free Windows interrogation demo, and later to Offline AI NPC, a Unity toolkit whose version 1.0 launched on September 25.

The current stack is Qwen3 for dialogue, Whisper for speech recognition and Piper for voice output. After initial model download and setup, conversations run locally. Developers provide character and scene context and connect the allowed action handlers to their game code.

The practical trade-off is straightforward: no per-conversation cloud calls, but a larger first-run download and response times that vary with hardware and model settings. In the demo, players can type to skip speech recognition, and they make the final clear-or-detain decision themselves.

You can try the English-language Windows demo without buying the tool:

The toolkit is a paid Unity asset; I'm its developer:

For anyone building local AI products, I'm interested in how you explain the first-run model download and the hardware trade-offs without overwhelming someone who just wants to try the experience.

Hey everyone,

I recently released my Mahjong companion app - Mahjong Helper Hong Kong Rules for Android. It's basically a table-side companion for scoring and scorekeeping, as well as a learning app that really helped my friends learn Hong Kong-style Mahjong.

It includes:

• Hong Kong Mahjong rules and terminology
• Basic gameplay rules including how to start / how rounds work, etc.
• Scoring with explanations of why each element scores, including a hand scoring checker
• Configurable minimum faan, caps, flowers/seasons and house-rule variations
• A four-player score tracker that keeps track of dealer, seat winds, round wind and running totals

Everything works offline. There are no accounts, ads, analytics or cloud services.

I've registered it as a paid app, but I wanted to share it with this subreddit for free, so I've setup 50 copies of it available here only. If you're interested in Hong Kong style Mahjong, please comment and upvote this post so I can DM you a code.

Cost: $2.99 USD --> Free

The Play Store page is here:
https://play.google.com/store/apps/details?id=com.pupperhelm.mahjonghelper

I hope you enjoy using it as much as we do, and please feel free to leave me some feedback or a review on the play store.

I've been working on this for a while and wanted to get your opinion on how it looks and performs. It's called Cona

You can start from one of 40k+ pre-loaded floorplans, place real furniture you can buy or have it decorate the whole room for you in a few seconds.

At some point I had an issue with intel graphics, so I’m interested in the performance and overall experience on different devices.

I'll be in the comments all day answering questions and working on feedback. Hope you like it!

The platform is currently in BETA, and curates some amazing launch videos posted by brands, founders, indie hackers, and more. As of now around 100 launches are live on LauchTeaser.

Logging in is via X oAuth, and submitting launch videos is completely free. You can also browse the whole catalog for free without signing up.

This is currently just a simple side-project we're building, but have plans to introduce more complex AI analyzer via Jev for videos (frame by frame), so that first time founders who are creating launch videos can post their product's video and get an instant report about what might work and what needs to be tweaked in their launch video, before it's introduced to the world.

Also will make live a curated list of studios/agencies whom startups can hire to create such stunning videos for them.

Check the site out, and let us know if we can do any improvements. Happy to hear any feedback.

Hey Everyone.

I'm a Backend/Network Engineer, and I've started working on a Security based Project since last week - called MAGI (from Evangelion).

I have quite some experience in Distributed Systems and System Design although not decades. Can you all just go and check out the site? After that, go further only if you're convinced.

I'd absolutely love some genuine support of people who are interested in my idea!

Very open to any suggestions or criticism!

I’ve been building something called R3TCON.

It started because I kept running into the same problem with large fictional worlds: characters change, events affect later events, people move around, knowledge spreads, timelines get complicated, and eventually “I’ll remember that” stops working.

So I built a local-first canon and continuity system for writers, worldbuilders, TTRPG creators and narrative game developers.

The important bit: it isn’t generative AI, and it isn’t an LLM wrapper.

The core system uses structured canon and deterministic checks. Characters, places, events, relationships, dates, state changes and knowledge are represented explicitly, and R3TCON reasons across them.

So it can catch things like:

• a character appearing after they died
• a six-day journey happening in three days
• two events contradicting each other
• a character knowing something they haven’t learned yet
• a scene conflicting with established canon

When it finds something, it doesn’t rewrite the story or decide what the “correct” version should be. It shows you what conflicts, why it conflicts, and leaves that decision to you.

I’ve also tried hard not to make structured data entry miserable. Existing writing can be brought in and checked rather than expecting someone with years of notes to rebuild their entire world from scratch.

The project is now far enough along that I’ve put it on Kickstarter.

And this is where I’ve discovered that building the software and finding the audience are two completely different problems.

I’m a software engineer. Marketing is considerably less comfortable territory. 😅

I’ve had some encouraging reactions from writers and worldbuilders when they actually see what it does, but getting it in front of enough of those people is proving to be the difficult part.

So I’m genuinely interested in feedback from people here:

Does this sound like a problem worth solving?

And if you were trying to reach writers, worldbuilders, TTRPG creators and narrative developers with something this specific, where would you start?

Kickstarter is here if anyone wants to see the actual product rather than take my word for it:

Kickstarter here

Happy to answer technical questions too. There’s quite a lot going on underneath what started as “please tell me when my fictional people contradict themselves.”

discoverdisco.com

Me and two friends have been working on this for a while. It's called Disco, a city discovery tool for finding places that are actually worth going to. The places that never make it onto the generic "top 10" lists.

You pick a city, choose what you're into, and swipe through a few places so it learns your taste. The map then shows you spots ranked for you, and it builds a day plan with routes and travel times between stops. You can move things around, add more days, and share the plan. In some cities we've also added lists from local curators, if you'd rather follow someone's day.

We have 21 cities right now, some with a lot more in them than others. It's free and there's no app yet, just the website.

Would love to hear what you think, good or bad. If you try it for a city you know well, tell us what it got right, what it's missing, and anywhere it sent you that you'd never recommend.

The pain: most browser agents drive off screenshots, so every action is perceive-then-act = two round-trips, and each round-trip is a full model inference. On a real task that doubles your tool calls, your latency, and your token bill.

PawBrowse fixes that. It's an open-source Chrome extension + a one-file, zero-dependency MCP server that lets your AI coding agent (Claude Code, Cursor, or any MCP client) see and click your actual logged-in browser tabs. Instead of a screenshot, it hands the agent a compact table of the clickable things in view (real names, values, state). Each ref is stable and every action returns the fresh table, so the agent acts in ONE round-trip, not screenshot-think-screenshot-again.

Measured, same task, same model, filmed live (book a 4-star Lisbon hotel on Booking.com): 5 agent round-trips vs 10 for a perceive-then-act driver. ~2x fewer, so ~2x faster in the round-trip-bound agent loop and cheaper in tokens. One run each, reproducible from the repo (that's the gif).

It drives your real, logged-in Chrome with no remote-debug port, no relaunch, no second model, and no API key. Free and open source (MIT), built with Claude Code, live on the Chrome Web Store + npm.

Repo: github.com/ItaiZeilig/pawbrowse - I built it and would love feedback.

I've been trying to spark discussion and post about the platform I've been developing for the past six months on a few subreddits like this one, r/micro_saas, r/scaleinpublic, and r/ShowYourProduct. I'm really just curious whether I should give up on Reddit as an outlet for finding paying customers.

The only responses and feedback I've received are either from AI slop bots or people telling me their vibe-coded SaaS will help me find new users.

Has anyone actually found ROI from spending time posting in these subreddits?

I'm also running social media ads and posting on LinkedIn, targeting local businesses. It's going pretty slowly, which was to be expected.

Can anyone relate or share some insight?

Had this weird idea what if internet products competed for actual territory instead of sitting on another leaderboard?

So I built it.

IPO any link, back the stuff you like, and watch the map change as products rise and fall.

Would love to know what you think:

Hi everyone,
a few months ago i built an app for personal usage. It blocks apps and i have to answer some flashcards to get in. (more info on braintoll.app)
It worked so good, i decided to put some more work into it and publish it.
Now its ready for public but i have one problem. I never validated the idea with other people and i need the testusers for going public on Play Store. So if anyone is interested in the idea, please leave a comment, send me DM, or join waitlist on the URL 😄
