by•
Built by a 21-year-old university student who got tired of bloated fitness apps. Kintore tracks weight training, cardio, and body weight — with PR detection, streak tracking, and progress graphs. No download needed. Works on any smartphone as a PWA. Just open the link and tap "Add to Home Screen". 100% free. Built with Firebase + vanilla JS.

I'm Yuta, a 21-year-old university student from Tokyo who built this workout tracker from scratch using Claude Code + Firebase. I got curious about whether I could build a fully functional fitness app solo — so I did it. No app store needed. Just open the link on your phone and tap "Add to Home Screen". Would love your honest feedback — what features would make you actually use this daily?
