Frequently asked
RestIQ is a motion-powered 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 to rest.
Incredibly 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.
RestIQ tracks the length of every set and rest, including how far each rest went over your target. It also computes your average set and rest durations, and provides your total workout time. Everything is presented in the summary view once you finish your workout. RestIQ Pro users have the added ability to review all past sessions at any time.
No. RestIQ runs reliably in the background, even when your screen is off. 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.
Yes. RestIQ has no accounts and never collects personal details like your name, email, or location. Your motion data and workout history stay on your device. Full details are in the Privacy Policy.

Because RestIQ costs money to run at scale every single month. Keeping the Live Activity on your Lock Screen and Dynamic Island up to date is not something an app can do on its own. It requires a server that sends a push notification to your phone every time your workout changes state, and that server bills several times a workout for every user. A one-time purchase cannot fund a cost that never stops. The subscription covers the infrastructure that makes the Live Activity work and funds the ongoing development of the app.
Anytime, through Apple. On your iPhone, open Settings, tap your name, then Subscriptions, and select RestIQ. Cancel before your trial ends and you will not be charged.
