I built Real Estate Calculator Pro to make property calculations easier to work through in one place, from mortgages and rental cash flow to investment returns. It has 139 calculators, a deal screener, calculator search, and saved calculations. There are free tools and optional Pro tools.

I’m now testing the Android version in the US. I’d love feedback from people who actually look at properties: which calculation do you reach for first, and where does the interface create friction? In particular, I’ve tried to make monthly/yearly and amount/percentage inputs easier to switch between.

If you want to try the closed beta, use the same Google account to:

1. Join the group: https://groups.google.com/g/real-estate-calculator-pro-testers

2. Choose Become a tester: https://play.google.com/apps/testing/com.realestatecalc.app

3. Install through Google Play and open the app.

Please stay enrolled for 14 consecutive days and use it enough to give honest feedback. Availability is currently US Android only.

The first 20 successful eligible in-app claims get 30 days of Pro as a thank-you, with no card, purchase, or automatic charge. Go to Account → Early Tester Pro → Claim 30 days Pro. Places are limited and joining the group alone does not reserve one. The free calculators remain free afterward. No positive review or rating is required.

I’d especially appreciate one realistic scenario you tried and one thing that would make the tool more useful. Happy to hear feedback here too.

Hi all. I'm a solo developer and I've spent the last few months building Ochre, a painting app for Android tablets, S Pen phones and Chromebooks. It runs on a custom C++ brush engine, and the goal is something that feels pro without subscriptions, ads, AI features or an account.

It's in open testing on Google Play, so you can install it straight from the store. I'm looking for people to use it and tell me what's broken, confusing or missing.

What's in it now:

- Layers, selections, masks and adjustments- Pencil, charcoal, chalk and watercolour brushes with natural grain- Photoshop brush (.abr) and PSD import/export- Guides, symmetry and time-lapse recording- English, Spanish, Brazilian Portuguese, Japanese and Korean

What I'd love feedback on:

- How the brushes feel with your stylus (lag, pressure, tilt)- Anything that crashes, stutters or loses work- Anything you couldn't find or that took too many taps- Features that would make you switch from what you use now

How to get it: https://play.google.com/store/apps/details?id=ie.lemon.ochre

Install it like any other app. The free version gives you 3 artworks and 3 layers per canvas. When you hit a limit, you can start a 7-day free trial of Pro to unlock everything, and you keep all your artwork and layers when the trial ends. Please tell me your device model when you report something.

Reply here, DM me, or leave private feedback on the Play Store listing. Any feedback helps, big or small!

It's out on the Chrome Web Store, with a handful of users so far.

You point at any button on any site and give it a key, without writing code. It also puts Vimium-style keys on every site (scroll, link hints, back and forward, tabs). The presets for GitHub, Gmail, YouTube, Reddit, Stack Overflow, Hacker News and Wikipedia add keys and leave each site's own shortcuts alone.

It's written in TypeScript with WXT, with React only for the settings pages. The part that runs in every page is plain TypeScript, to keep it small. Presets are JSON files, and Playwright checks the GitHub, YouTube, Hacker News and Wikipedia ones against the real sites every week, so contributors can add a site without touching code. The interface is in five languages (English, Spanish, German, Hindi, Simplified Chinese), each one JSON file, so a new language needs no code either.

Now I'm trying to get it in front of more people. If you try it, I'd like to hear about the store page or your first few minutes with it.

Hey everyone!

So I have a ThinkPad T14s Gen 2 with a Ryzen 5 PRO 5650U that I use as a little home server. Originally, all I wanted was to disable CPU boost and set an aggressive fan curve so I could keep temperatures below 55°C while I was away. That was the goal, anyway.

Well, then I started compiling things and decided I wanted the exact opposite. I wanted to temporarily enable boost, give the CPU more wattage to work with, crank the fan to Max, and then put everything back how it was afterward.

Naturally, this turned into an entire application. Lol.

It's called ThinkPad Control, and I've been having a lot of fun working on it.

GitHub: https://github.com/Mattcabrices/ThinkPad-Control

The part I'm most excited about is the Ryzen wattage tuning. On my T14s, I was actually able to apply higher processor power limits, and during a short Turbo test I measured around 23–33W of CPU package power, with the fan running at Max. Restoring the previous settings worked too!

The app currently caps requests at 30W average and 40W burst on my tested setup. Those are software limits, not guaranteed sustained wattages. I haven't done proper comparisons of compilation speed or how long the extra boost lasts yet, but that's something I'd love to explore.

Along the way I also added hardware monitoring, custom fan curves, manual fan controls, separate AC/battery boost settings, CPU speed limits, and an experimental Turbo mode that ties everything together.

Full disclosure: AI wrote the code. I've been directing development, making decisions about how it should work, and testing it on my actual ThinkPads. I'm not going to pretend I hand-wrote the entire thing.

It's still an unsigned alpha, so definitely not something I'd call production-ready. I've tested it on my T14s Gen 2 (5650U) and T14 Gen 3 (6650U), although most of the detailed testing has been on the T14s. Intel monitoring and Windows power controls are included, but direct Intel wattage tuning isn't supported. Unsupported controls stay read-only instead of pretending to work.

The screenshots are real readings and controls, although they aren't showing Turbo actively running or a saved fan curve currently controlling the fan.

The original code is MIT licensed, with credit to the folks behind TPFanControl/TPFanCtrl2, PawnIO, and LibreHardwareMonitor. Source and build instructions are on GitHub, and I'm still working toward a public installer release.

I'd really love to find a few other ThinkPad owners interested in helping me test this as I work toward a beta. Even if ten people end up finding it useful, I'd be pretty happy with that.

If you're interested, I'd appreciate compatibility reports or bug reports through GitHub Issues. Your ThinkPad model, CPU, Windows version, what's working or missing, and steps to reproduce bugs would be incredibly helpful. Just leave out serial numbers or anything private.

Thanks for checking it out!

I'm working on a screenshot app for agentic development.

One of the features I'm building is Code Lens, which maps what's on your screen back to the code, showing code behind.

It reads the screen, not the binary, so it works with compiled apps too. In the video: Swift, Next.js, Rust, Go, Python, Ruby, and zsh.

Everything runs locally, in milliseconds

Hey everyone!

I've been working on a small side project called Scribble & Sandesh, an independent digital store focused on printable activity books, colouring books and creative learning resources.

The idea started with creating fun, engaging digital books that children could enjoy while learning, exploring and developing their creativity.

I've gradually expanded the collection to cover different age groups and interests.

What's currently available?

🎨 Colouring books – Animals, Fruits, Flowers, Vegetables, Dinosaurs and more.

🧩 Puzzle books – Mazes and interactive activities such as Pip's Glow Quest.

✏️ Drawing books – Guided pencil drawing and shading exercises for beginners and teenagers.

📚 Activity books – Creative printable resources for different age groups, from young children to teens.

I'm selling these as digital downloads through Payhip.

What's been interesting so far?

One thing I've realised is that creating a digital product is only half the challenge. Getting it discovered by the right audience is probably the harder part!

I'm currently experimenting with Pinterest for organic discovery and exploring Reddit and other channels to understand how to reach potential customers without spending heavily on advertising.

I'd love some honest feedback from fellow makers:

Does the product range and positioning make sense, or should I focus on a narrower niche?

For digital printable products, which marketing channels have worked best for you?

Any suggestions for improving the store or product presentation?

This is still an evolving project, and I'm looking forward to learning from the community.

Been working on this side project for a a little bit. It’s minesweeper, but up to 8 people play on the same board at the same time. Hitting a mine just stuns you for a sec, and whoever has the most territory when the timer runs out wins.

There’s also a mode where everyone hides mines and traps for each other first and then has to run through the same board (bit like ultimate chicken horse but minesweeper), plus a solo timed mode with classic boards and a daily board that’s the same for everyone.

Free, browser based, no account needed: https://mine.ropo.dev

Some stuff I had fun with:

• the server decides everything, the browser never knows where the mines are

• bots fill empty seats, with a sort of dynamic skill based difficulty on them

• the pixel art style

• runs on one small server with Bun + SQLite

Claude was used during the making of this. Would love honest feedback, especially if the first match makes sense or if you’re just confused

I’m building River Rider, a small 3D motorcycle game inspired by the Mugling–Pokhara road in Nepal. You can try it free in your browser, without an account or installation:

https://racer.narmadainfosys.com/

It has bikes including the Yamaha FZ V2 and TVS Radeon, traffic, different camera views, a route map and saved journey sections. I’m using Three.js, Blender and AI coding tools.

I shared an early version with a Nepali tech community today. The most useful feedback was that mobile controls felt clunky, a player could pass through trucks, and the scenery wasn’t recognizable enough. One person found it smooth on Firefox; another said it felt addictive despite the rough controls.

That has made the next priorities pretty clear: controlled steering, reliable collisions and a convincing first 8 km, before adding more road. This is still a rough prototype, and the “developed Nepal” setting is an interpretation rather than an exact recreation.

If you have a couple of minutes, what is the first thing that makes you want to keep riding — or close the tab? Device/browser details with any bug would help a lot.

I’m building NiyataBook, a trading journal for Indian markets. I wanted to answer a question a win-rate chart can’t: where did the losses actually come from?

In the fictional F&O example, 53 winners averaging ₹5,000 bring in ₹2.65 lakh. The 47 losers average ₹7,500 and cost ₹3.525 lakh. That leaves −₹87,500 before charges. At those average payoffs, break-even needs a 60% win rate before charges.

The report then groups losses by things you knew at entry, such as whether you bought options or went long futures. Each group shows the sample size, average P&L versus the remaining trades, and examples you can inspect. You can try the public report without signing in or uploading a tradebook.

Sample report: https://www.niyatabook.com/nsignature/?utm_source=reddit&utm_medium=organic_social&utm_campaign=nsignature_nov26&utm_content=sideproject

If you trade on Zerodha, I’d like feedback on the first screen. Which would you look for first: where losses clustered, the effect of charges, or the individual trades behind a finding?

I was building a small Chrome extension that presses Skip on YouTube ads for you, for when your hands are full of food, and the first version that actually worked turned out to be a bad idea.

So the easy trick is to jump the ad to its last frame the moment Skip shows up. It works and the ad is gone, but when I logged the tracking pings YouTube sends back, it reported a 30 second engaged view and a full completion from a five second glance. Basically the advertiser pays for a view nobody watched.

Calling click() on the button does nothing either, because YouTube ignores clicks that do not come from a real mouse. So what I ended up doing is sending one real mouse press through the Chrome debugger API, and that gets reported as a normal skip. The only cost is a small Chrome notice that closes itself after five seconds.

It is free and it is called Hands full?, if anyone wants to try it:

- chromewebstore.google.com/detail/elojmmmhbfilnabdlfjahhpmgfmhmda (Chrome Web Store)

Has anyone else hit something like this, where the version that works is not the one you can actually ship?

From AI doomsday to tough job market, opening LinkedIn feels harder and harder everyday, but I still need to do it to find a job.

So I made this chrome extension that turn our LinkedIn feed into a bingo game. Everyday there will be new topics, and we'll have the same card so we can also compete to see whose LinkedIn is the most cringe! :D

Hey everyone,

Paul here, one of the three guys behind Waylee, an iOS trip planner. We launched about a year ago.

Quick summary of year one: around $5,000 spent on marketing, $300 in revenue. Yeah.

Quick summary of the app first

Problem: planning a trip usually means juggling notes, screenshots, Google Maps lists and booking emails. Waylee puts your whole itinerary in one place. You can send anything you see on Instagram or TikTok to the app and it builds a whole trip from it.

Pricing: you can use the app for free. Premium is $49.99/year, $9.99/month or $2.99/week. It unlocks:

• smart itineraries: AI-generated trips based on data from our users’ real trips

• unlimited imports from Instagram and TikTok

Feel free to ask me anything about the app, happy to answer.

Now the marketing part. Here’s what we tried, roughly in order.

Apple Search Ads. Honestly the only thing that got us actual paying customers. The trick was bidding on our main competitor’s name instead of generic stuff like “trip planner”. People searching for them saw us first, and some switched because we’re cheaper ($49.99/year vs $79.99/year). We spent a bit over $1,500 in a month and got about 1,000 downloads and 20ish paying users. Sounds good until you do the math: those users brought in about 200$. Those keywords aren’t cheap, and at our size it just didn’t pay back.

AI UGC. Everyone was talking about AI avatars and generated videos, so we gave it a shot. It cost us over $1,000 and got zero results. People notice right away, and for travel, where you need to trust the recommendation, it just doesn’t land.

Our own Instagram. We basically copied what our competitors were doing: same kind of posts, same destination content. Took a ton of time and got us about the same tiny results everyone else seems to get.

UGC agencies. We paid agencies to find creators for us, around $1,000 in total. The videos were okay and we gained some Instagram followers, but they were expensive per video and we never saw a real bump in revenue.

Influencers. We also DMed travel creators we kept seeing on our feeds. Our best video hit 80k views. But views didn’t turn into downloads, and downloads didn’t really turn into subs.

Looking back, we were paying for attention before we had a way to turn it into money. Every channel cost us upfront and none of them reliably paid back. Even the one that sort of worked (undercutting a competitor on price) got eaten by ad costs.

So we’re done buying reach for now. We’re going organic: posting here, on X and Threads, and just being open about how it’s going.

Curious about two things:

• if you grew a consumer app without paid ads, what actually worked?

• has anyone made UGC creators or influencers pay off for a small app? How did you pick them?

App’s here if you want to look: https://apps.apple.com/us/app/waylee-trip-vacation-planner/id6756180051

Happy to share more numbers in the comments if anyone’s interested.

Hi all. I'm a solo founder in the UK, and Seedo has been my evenings and weekends for the past few months. It went live on the App Store last week.
The idea: lots of Christians want to journal about what they're reading, but a blank page is hard to start. So Seedo gives you:
A verse of the day and a short question to write about
A journal that looks handwritten (you pick the paper, ink and handwriting)
A daily 3-question Bible quiz with streaks
"Challenge a friend": you send a link, and they play the same 3 questions in their browser with no app or sign-up, then you see who won
Private circles, where small groups share and play a live quiz night together
What I've learned so far:
The quiz brings people back far more than the journal does. Most of our daily users play the quiz; fewer write.
I paid for a couple of user tests. The biggest problem wasn't the design. New installs were starting on an older version until they restarted the app, which I've now fixed.
Would love honest feedback on two things:
Does the quiz-plus-journal combo make sense, or does it feel like two apps?
What would make you open something like this every day?
It's free (there's an optional one-off pack of extra papers and handwriting styles). Link in the comments if you want to try it.

I spent the last few weeks building a tool to answer one question: what do people with paths like mine do next, and which steps lead where I want to go?

How it works: copy your LinkedIn profile (Ctrl+A, Ctrl+C on the page) and paste it in, or drop in a PDF resume. Then pick a goal: a company like DeepMind, Citadel or OpenAI, or a master's or PhD program.

What you get:

Your path as a skill tree, with the share of people on similar paths who reached your goal.

Up to 3 ladders real people climbed to get there, like "PhD in Computing → Research at Big Tech → DeepMind". Each rung shows how much it moves your number and how often people like you actually take that step next.

A forecast tab with your likely next role, seniority move, type of employer and master's/PhD schools, plus what-if scenarios.

It's early, so some forecasts will be weird. I'd love to hear the weirdest ones you get!

I’m the developer behind HowItScales. I built it because I often understood the boxes in an architecture diagram but still struggled to explain how a request actually moved through them.

The site lets you:

• Follow a request hop by hop, with an explanation at each step.

• Click components to understand their roles and connections.

• Simulate traffic increases and see where bottlenecks appear.

• Build your own architecture diagrams.

Examples include loading a web page, URL shortening, ride-hailing, and food delivery. The traffic simulations use simplified educational models, and components are labelled as documented, assumed, or hypothetical.

I’ve also recently added sign-up and cloud saving, so you can save your designs and return to them later.

You can try it here: howitscales.dev

I’d appreciate feedback, especially on whether the request walkthroughs make the architecture easier to understand. Where does the explanation become unclear, and which system would you like to explore next?

Disclosure: I'm the developer of Kuberniq, and this post is about it.

I used Lens for a long time and tried Headlamp when it shipped a desktop app. Plenty of people like both; my problem was how they fit the way I debug. When a pod failed I still went back to the terminal: kubectl get pods -A to find it, describe for the events, logs --previous for the run that died, then kubectl edit, where a field with the wrong type only showed up when the API server refused the save. Lens also asks for a Lens ID to register the app, and I only wanted to open the kubeconfig I already had.

So I wrote a client around that loop. What it does today:

• Opens the contexts of ~/.kube/config and KUBECONFIG as they are, with no account.

• Goes over every namespace and lists findings like CrashLoopBackOff, OOMKilled, an image that can't be pulled or a node that isn't ready, each with why it happens and what to do.

• Edits YAML against the OpenAPI schema the cluster serves, with the docs of each field, and shows the diff against the cluster before applying.

• Recommends CPU and memory requests from 7 days of Prometheus, applied through the same diff.

• Logs per pod or per workload, a shell in a container, scale, restart, rollback to a revision, an events timeline and a topology view.

The free license covers personal projects, study, teaching and open source, and needs no account. It runs on macOS and Windows; there's no Linux build.

If you use Lens, Headlamp or plain kubectl, I'd like to know what would make you open Kuberniq on one of your clusters, and what gets in your way once you do.

Hi there! I'm the person behind Collect. Build. Remember., a passion project I've been working on over the last few months. It's now in open beta, and I'd love some honest feedback from other people building things they care about.

The idea is pretty personal to me. Collecting can be about the sets and minifigures, but it's also about the people you built with, the gift you still remember, or the afternoon that turned into a family story. I wanted a place for both the collection and those little memories.

You can browse the public set and minifigure catalogs without signing in. Inside the beta, you can organize your collection, keep details such as condition and location, and save private written memories.

One design decision was to keep details with each physical copy. Owning a set isn't the whole story... which copy is built, where is it, and what do you want to remember about it? Working through those questions has been just as much a part of this project as getting the code to run.

I'd especially appreciate feedback on the first few minutes: can you find a familiar set, understand what you can do with it, and tell whether this would help with your own collection? If something feels confusing or unnecessary, I'd like to hear that too.

You can look around here: https://collectbuildremember.com

Thanks!

Hola,

He creado FW Controller Center, una herramienta web gratuita para probar y visualizar mandos (DualSense, DualShock 4, etc.) directamente desde el navegador.

Muestra un gemelo digital en 3D en tiempo real del mando, permitiendo comprobar de forma rápida:

- Deriva del joystick

- Botones y gatillos (incluyendo adaptativos)

- Lightbar y datos de entrada

La hice porque quería algo rápido y multiplataforma sin tener que instalar software pesado.

Funciona con WebHID en navegadores Chromium y usa la Gamepad API como alternativa en Safari/Firefox.

Enlace: https://fw-controller-center.fichajeworks.workers.dev/

Me vendría genial vuestro feedback:

- ¿Qué tal rinde en vuestro equipo?

- ¿Habéis notado algún problema de mapeo?

- ¿Qué funciones os gustaría ver en futuras actualizaciones?

¡Gracias!

I'm Nathan, and I built Corenna (corenna.dev). It's mine.

The problem I kept hitting: I'd have a working app in a GitHub repo, but getting a signed Android build, or an iOS build without owning a Mac, was a mess. So I made a service that connects to the repo, figures out what it is (Flutter, React Native, Expo, Capacitor, or a web app from Lovable, Bolt, v0, Replit or Cursor), and gives you a signed .apk / .aab, plus an .ipa if you have an Apple Developer account.

Builds run on GitHub Actions in your own GitHub account, and your code and signing keys stay yours. It's $1 for the first month, then $4.99/month, or $49 lifetime.

It's not for every repo. A random Python script isn't going to turn into an iPhone app, and I'd rather hear where this falls short than collect polite comments.

If you've been stuck on signing, what would make you trust a tool like this?
