STACK

AI rep counter & all-in-one tracker

STACK launched on March 20, 2026 with 5 votes, #1,928 of 23,380 launches that month and more than 75% of that year's launches.

What it does

I built STACK from scratch to stop juggling fitness apps. It’s an all-in-one native Android tracker. • AI Rep Counter: Uses phone camera & computer vision to auto-count reps in real-time. • Workout Tracker: Logging, custom timers & routines. • Nutrition: Barcode scanner for macros & calories. • Social: Feed & 1-to-1 messaging. Tech: Native Android, Health Connect, offline mode. I'd love your technical feedback on the AI!
