Solo-built app just passed a bigger competitor on Google Play visibility score https://preview.redd.it/cmy3haru6veh1.png?width=1510&format=png&auto=webp&s=6c9f05bd5d22a012f123e4c4f6f26d1a7c85c5e3 Sharing this because it's a small win but it's mine. I'm the solo dev behind skillably, a study app where you upload your own notes or PDFs and it turns them into quizzes and flashcards, adapting based on what you actually get wrong. No team, no funding, built around a day job.

Solve daily coding challenges with AI assistance and track your developer streak.

I built this because AI was making me a dumb&lazy engineer I noticed something sad about how I use AI. I was shipping faster, but practicing less. I could get answers quickly, but I was losing the habit of working through the fundamentals myself. So I built Unrot: short daily challenges for developers across languages, system design, architecture, data engineering, and other tracks. Game/xp and rewards system, a tiny bit competitive. No signup required to try it: https://unrot.dev
