Frequently asked
RestIQ is an autonomous rest timer for weight training. It uses your iPhone's motion sensors to detect the moment you put your phone down to lift, and automatically start your rest timer when you pick it back up.
Extremely accurate. RestIQ's motion algorithm is precisely tuned to understand the context of your workout using your iPhone's accelerometer, gyroscope, and magnetometer data. It can, for instance, reliably distinguish a steady hand from a resting surface, even in gym environments with significant ambient vibration.
No. RestIQ runs reliably in the background with the screen off or the phone in your pocket, and it plays over your music instead of interrupting it. Your timer stays live on the Lock Screen and Dynamic Island, with a sound and vibration the moment your rest ends.
RestIQ works on any iPhone running iOS 17 or newer.
No. RestIQ is engineered to run efficiently in the background during your workout and shuts the motion sensors off the instant your session ends. The impact is on par with streaming music in the background.
