BarbellBeat

There's one question I kept coming back to during my workouts. Why does everyone rest for the same amount of time? Some people recover fully in 60 seconds. For others, their heart rate is still elevated after 90. Yet most training still runs on a fixed timer. So I made this. BarbellBeat uses your Apple Watch to track how your heart rate recovers between sets, and tells you when you're ready for the next one. - Real-time heart rate recovery tracking - Haptic alert the moment you've recovered - Every workout and rest interval saved automatically Train by recovery, not by the timer.
