Yay is my first-ever iPhone app. I don't know Swift, but I was able to almost completely vibe-code it with Cursor. Please give it a try let me know what you think! Use referral code PH5 to get your first 5 photos for free.

Bluesky has gotten a lot of momentum lately, but it lacks proper analytics. That's why I built Bluesky Counter. The first (and free!) analytics tool for Bluesky.

Hi PH, I'm back! Last year I launched the first AI-powered interior designer. Today, I'm launching the first AI interior consultant! Advice by Room AI gives you practical advice on how to improve your interior design.

Last year, I launched the first AI-powered interior design app. Today, I launch what I hope to be the best AI-powered interior design app. 😄 AI technology like Stable Diffusion is really powerful, but getting it to do exactly what you want isn't always that easy.
