Quick Help
Everything you need to keep moving
CoreHabit is designed to stay simple. Most issues can be resolved with the steps below.
See your live heart rate
Wear a compatible heart-rate sensor, allow CoreHabit to read heart rate in Apple Health, and give the first reading a few seconds to appear after your workout begins.
Save workouts to Apple Health
After you approve Health access, completed sessions can save automatically as Core Training workouts. Your sit-up count remains available in CoreHabit’s on-device history.
Review or change permissions
Open Settings, choose Health, then Data Access & Devices and CoreHabit. Motion access can be reviewed under Settings, Privacy & Security, Motion & Fitness.
