## What is 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.

### 1.2.0 — 2026-07-23

Major improvements to recovery measurement, plus a new 
stats screen to track your recovery capacity.

Improved target heart rate
Rebuilt how the recovery target is calculated so it stays 
accurate from your first working set through the end of 
your session.

Personalized recovery
BarbellBeat now measures how much your heart rate drops in 
the 30 seconds after each set (HRR30), and adapts your 
target to your own recovery rate over time.

New stats screen
See your recovery rate, how it changes over weeks, and a 
set-by-set breakdown of each workout.

Also
- Set-level heart rate details
- Reminder haptic if you rest too long
- Redesigned info screen

### 1.1.3 — 2026-07-16

Improved rest accuracy early in your workout.

Fixed an issue where the recovery target could be set too high
right after warming up, so you get accurate timing from your
first working sets.

### 1.1.2 — 2026-07-14

Improved rest measurement during longer workouts.

Your recovery target now adapts to your actual heart rate
throughout the session, so late-workout rests stay accurate
even as your baseline rises.

- Added a first-run hint for ending a workout
