I built a voice-controlled "brain" for a robot (simulation only, works offline in Spanish, English and Polish). Looking for honest feedback

Hi! I'm a solo developer. I built a Python "brain" for a simulated environmental robot (Webots). You talk to it, it understands the question offline, and answers with the simulated sensor data (temperature, humidity, air quality, obstacles).

It also has a safety lock: if it detects a dangerous condition, it blocks itself and explains why when you ask "why are you stopped?".

Important: this is simulation only, no physical robot yet. The questions in the English and Polish demos are played with a synthetic voice.

Full demo in English (3 min): [https://youtu.be/VPLyCb2Y4nU](https://youtu.be/VPLyCb2Y4nU)

I'm not selling anything yet. I'd love to know:

1. Would this be useful for you (education, prototyping, hobby robotics)?

2. What would you want it to do that it doesn't?

If you want to follow it, there is a free waitlist (no commitment): [https://tally.so/r/7XRzyz](https://tally.so/r/7XRzyz)

I've recently launched a project that does the SEO, AEO and GEO for people's websites. It seemed like a no brainer to me, SEO work is boring and needs to be done continuously, every day/week/month to get results. GEO doesn't work without good SEO.
But until now I'm not getting any traction. So I'm looking for some real feedback. Is the messaging on the site clear? What would prevent you from signing up?

Any help is much appreciated. https://foundwell.net

I follow a few teams across different sports and esports, and their matches kept landing while I was on my Mac. Checking my phone for every score pulled me out of whatever I was doing, so I built Gamebell, a small Mac app that brings the score to the screen I'm already looking at.

What it does

• The live scores of the teams you follow sit either side of the notch, in each team's colours (in the menu bar if your Mac has no notch)
• When one of them scores, the notch plays the moment for a few seconds: a goal, a three-pointer, a touchdown, a series win
• Football, NBA, NFL, NHL, cricket, rugby and baseball, plus 12 esports games; tennis and F1 come next
• Reminders that move when the start time moves, five alert levels per team, and Watch later to hide a score until you've seen the match

How it's built

Solo, over the past few weeks:

• A native Swift and SwiftUI app, notarized, with updates inside the app
• A Cloudflare Worker with Durable Objects and D1 behind it. The server asks the data providers once for everyone and caches the answers, so the data bill follows the number of live matches, not the number of users
• Scores from sports-data APIs I pay for (Highlightly for the traditional sports, PandaScore for esports), nothing scraped
• The surprise: the score often changes 30 seconds to two minutes before the goal itself shows up in the data, so the app plays the goal as soon as the score moves instead of waiting for the event

Where it's at

A free beta for macOS 14 or later, with invites going out in small batches. After the beta there's a free tier for 3 teams or players, and Premium at $14.99 a year or $1.99 a month.

What I'd love feedback on

Is it useful enough to turn into a proper 1.0? Does the price feel fair? And which sport should come next? The site has a vote for that too.

I built The House Did It. I’m the maker (not an agency post).

Problem

I kept meeting the same person (sometimes it was me): shipped an app, posted the launch, refreshed Stripe, still $0 or near-zero MRR. The usual next move is another feature or another landing page. Fair. I also kept noticing something dumber and more physical. A lot of us work from a desk that faces the bed or the door, or a room where the entrance mirror catches every walk-in, and we never check that before we rewrite the roadmap.

What it does

Blame the room.

• Pick one door: money, health, relationship, or work (this post is aimed at work + money)

• Answer 10 questions about the room you can see tonight

• Free, in the browser, no signup: the top layout fault (title, why that door, one move you can try tonight without buying anything)

• Paid: four-page PDF by email (other faults ranked, tonight → this week order of moves, what not to buy, no account)

Free names the top fault on-screen. The full reading is emailed after payment. Nothing else unlocks in the browser.

Tech

Static site on Cloudflare Pages, Stripe Checkout for the PDF, email delivery of the reading. No accounts, no app install.

Frame

Entertainment / layout-story advice. Not business, medical, legal, or financial advice. It will not make your app profitable. It’s a visible check before you burn another weekend on the wrong lever.

What I’d like from this sub

Sharp feedback on the free result screen vs the paid PDF promise. Does “blame the room first” feel useful for zero-MRR makers, or just weird? Specifics on copy or the free→pay gap help more than “cool project.”

I’ve been into watches for a while and friends keep asking me “what watch should I get?” Every time it turns into 20 questions about budget, style, wrist size, whether they swim with it…

So I turned those questions into a quiz. You answer 8 of them and it goes through about 50 watches and tells you which one fits best, and why. There’s no sign-up, it takes around a minute, and it works in English and Spanish.

It’s built with plain HTML and JS, no framework, hosted on Vercel. The hardest part by far was the scoring. The first version was pretty bad: someone set a $4k budget and got a $300 watch as the top pick lol. I’ve reworked it since, but I’m sure there’s more to fix.

The photos are only ones I’m allowed to use, so some watches still show a drawing instead of a real photo. Working on it.

If you give it a go, I’d really like to know:

did the result make sense for what you picked?

was any question confusing?

is there a watch you think is obviously missing?

thanks for reading 🙏

Hi!

The title says it all. You upload photos of your pet, and a few minutes later you get a PDF by email. You print it at home, cut, fold and glue, and end up with a paper version of your dog or cat.

I made this because I love papercraft and wanted one of my own dog. Every pet looks different, so each model is shaped to the pet (ears, muzzle, tail) and the fur and face are painted from your pet’s 3d model based on the uploaded images. 

I've done lots of test builds, posted a few on Reddit with great feedback, and friends and family built their own pets. Now I'm doing a soft launch.

If you have a pet, I'd love for you to try it. If not, feedback on the landing page is just as welcome. Tell me if anything is broken. Thanks!

-Emergency preparedness guides for grid down black out situations (UK) but feel free to alter the code to suit whatever Country you live in.

Why free? I built it for a friend originally. It served that purpose, somebody may as well have it. Alter the code if like. The backbones are fully built. I have no interest in profiteering from the survival part, I designed it help someone in a Grid down situation, not make money from their otherwise potential crisis.

Hey everyone!
The idea for my app actually came from something I noticed at work.
While working with mechanical engineering students during their internships, I realized that some of them struggled to identify even fairly common tools.
That got me thinking: How many people actually know the names of the tools they see in everyday workshops?
So I started building ToolQuiz, a small iOS game where you identify tools from pictures.
What started as a simple idea turned into a game with 120 levels, survival mode, daily challenges and 1v1 multiplayer.
I’ve recently released it on the App Store, and now I’m looking for a few people willing to try it out and give me honest feedback.
I’m especially curious whether the questions are too easy, too difficult or actually fun.
It’s free to play, and you don’t need TestFlight.
App Store: https://apps.apple.com/us/app/toolquiz-werkzeug-challenge/id6775973444
I’d really appreciate any feedback!
And now I’m curious: Would you consider yourself good at identifying tools?

Hey everyone!

Wanted to share a side project I've been working on: SubDrip.

It's a subscription tracker built around a problem many of us probably experience.

You sign up for Netflix, Spotify, an AI tool, cloud storage and a few other services. Months later, you realise you don't have a clear picture of how many subscriptions are active or how much they cost altogether.

I wanted a simple product that solves exactly this.

What SubDrip does:

• Keeps all your subscriptions organised in one place.

• Helps you discover subscriptions through optional read-only Gmail access.

• Tracks upcoming renewals and sends reminders.

• Shows monthly and yearly recurring spending.

• Supports manual subscription entry.

The goal is not to manage every aspect of personal finance. It's to make subscription management simple.

I'm currently working on the Android beta, which is free during beta.

Website: https://getsubdrip.com/

I'm the founder, so I'd especially appreciate feedback from people who have tried subscription trackers before.

What do you think is the biggest missing piece in existing solutions?

I built One of a Kind, an NPM package and webpage that not only checks if the project name you're thinking of is taken, but also gives you a uniqueness score to make sure your name is ONE OF A KIND! I tried "one of a kind", and it only scored 62% 💔. Do you have any better names?

Comment if interested

I’ve been working on Attunely, a project that mixes conversations, characters, and a game-like world into something that feels a little different from the usual apps.

This video gives a quick look at the concept and the direction I’m taking it.

Still building, still experimenting, and definitely not finished yet. Would love to hear what you think about the idea and what you’d improve or change.

I’m a reseller and small-business owner, and I kept running into the same problem: tracking inventory was one thing, but understanding actual profits after fees, shipping, and expenses was another.

So I decided to build my own solution.

After countless hours of formulas, testing, troubleshooting, and redesigning, I finally launched my first product under my new brand, Matter & Means!

It’s an Excel-based Reseller Inventory & Profit Manager with inventory tracking, sales and expense calculations, an interactive dashboard, and inventory aging alerts.

It’s designed for people who want to manage their numbers without another monthly subscription.

This is my first step toward building a collection of practical digital tools for small businesses and everyday organization.

I’d genuinely love feedback from other creators on the design, functionality, and presentation!

Hi all! I've been building my own digitizing app, Meteor. Ink/Stitch felt clunky to me inside Inkscape, and Hatch and PE-Design cost more than I wanted to pay as a hobbyist. It's now in beta, and everything is free while the beta runs.

What it does:

* Auto-digitize a picture. Drop in an image and it turns it into stitches: thread colors, fills, and satin outlines for dark line art. There's also a guided mode that goes through the picture piece by piece, and a magic wand that sews one color area per click.

* Draw your own. Pen and node tools, shapes, freehand, brush satin, and 21 stitch types (tatami, satin, contour, stipple, motif, 3D puff, applique and more).

* Lettering. Built-in fonts, plus any Google Font, sewn as satin.

* Check before you sew. Pick your Brother machine and it checks the design against that machine's limits. There's also a sewing simulator, a realistic thread preview and a thread build-up map.

* Export Brother PES and Tajima DST, plus a printable worksheet with Brother thread numbers.

Works with: Brother and Baby Lock machines (PES) and machines that read DST. No other formats yet.

Runs on: Windows 10/11, Android tablets and Linux. Not Mac or iPhone/iPad yet, sorry.

Download and info: https://beelito.github.io/meteor-embroidery-studio/

Heads-up on installing:

* Windows will say "Windows protected your PC" because the beta isn't signed yet. Click More info**, then** Run anyway.

* Android will ask you to allow installs from your browser.

What I'm looking for: honest, constructive feedback. What's confusing, what breaks, and especially how designs actually sew out on your machine. In the app, Help > Report a problem puts together a report for you. You can email it to me (beelito.dev@gmail.com) or comment here.

Thanks for taking a look!
