Launching Thursday — the free workout app for people who hate workout apps 🐹

Hey! I'm a former pro athlete and amateur boxer who learned to code, and on Thursday I'm launching Cubex Fitness here on Product Hunt.

The short version: 250+ AI-designed workout programs, live heart rate on the workout screen, super-sets, full tracking — all completely free. No ads, no subscription, no account, works offline. I built it solo in Kotlin Multiplatform (one codebase, both stores).

I built it specifically for people who've decided they "don't need a fitness app" — because the app runs in the background (lock screen, watch) instead of demanding your attention.

Two questions for this community before I launch:

1. If you don't use a fitness app — why not? What's the dealbreaker?

2. If you do — what's the one feature you'd never give up?

Would love your honest answers 🙏
