Show HN: Pitwall – Live F1 Stats in Your macOS Menu Bar

https://pitstop-landing-inky.vercel.app/pitwall

I built this because I got tired of tabbing away during F1 practice sessions to check live timing. The idea was simple: keep race stats accessible in the menu bar without eating screen real estate. What it does:Live driver positions & session timing Real-time telemetry (speeds, gaps, tire info) PitStop F1 API integration Zero full-window footprintCurrent status: Live on the Mac App Store....

Re:I Created an AI App to Transform Your Home on Saturday April 26, 2025 @11:33AM (#43804497)
Hey everyone,

I’ve recently launched an app I’ve been developing called Roomify AI. It’s designed to help anyone quickly and easily redesign their living spaces using AI. All you need to do is take a photo of any room, choose your favorite style (modern, minimalist, cozy, etc.), and instantly visualize how the space can look.

The goal was to create something practical and fun, especially for those of us who aren’t natural-born interior designers or who don’t have a large budget to experiment. I’ve personally found it incredibly useful for visualizing my own home projects.

Due to the high costs of the OpenAI API, a subscription is necessary to fully use the app’s features. I’ve tried to keep the subscription affordable and fair, and your support would greatly help me continue improving the app.

I’d genuinely appreciate if some of you could give it a try and share your honest thoughts. Any feedback, good or bad, would be invaluable as I keep working to improve it.

Also, I’m curious—how do you feel about AI becoming part of everyday tasks like interior design?

I’ve always been fascinated by Formula 1, and recently I challenged myself to build something I hadn’t seen done well on mobile: a live map of an F1 circuit that updates every second, showing the real-time position of all drivers.

At first, I had no idea where to start. The initial version of the app was just a static SVG of the track and a bunch of placeholder dots. But I quickly realized that turning this into something dynamic and precise was going to require a lot more work—both technically and creatively.

One of the hardest parts was figuring out how to map GPS or telemetry-like data (or simulated equivalents) to the actual layout of the track. Circuits aren’t perfect circles or squares—they’re highly irregular, and getting the math right to interpolate positions smoothly along the path took a lot of iteration.

Once I had the basic movement working, I ran into performance issues. Updating 20+ driver positions every second, animating them smoothly, and not killing the battery or CPU on an iPhone took careful optimization, especially when combined with UI features like zooming, rotating, or switching to other parts of the app.

From there, the app grew: I added race results, driver and team info, standings, and more. But the live circuit map remains the heart of it—a tiny simulation of the race, in your pocket.

I learned a lot building this, from low-level animation tricks to dealing with refresh rates and background tasks on iOS. If you’re curious, you can check it out here

yes! if the title of the side loaded book is close enough to the original the app will detect which book it is when importing it. if it doesn't find it, i will leave the name of the book as it is and then you can assign a real book to it. do i make myself clear?
As someone who reads a lot on Kindle and also on paper, I was always frustrated by how messy it was to manage highlights—especially the My Clippings.txt file. So I decided to build a simple app for myself, and ended up publishing it in case others find it useful too.

It’s called Book Highlights and it lets you:

• Import highlights from Kindle using My Clippings.txt

• Create and manage your own personal book library

• Add quotes manually or scan them with your phone’s camera

• Sync everything across your Apple devices via iCloud

I tried to keep the interface clean and minimal, just focused on helping readers organize and revisit their favorite quotes. If anyone here gives it a try, I’d love to hear your thoughts or feedback!
