FREE BY DESIGN

Clear Intervals has no ads, paywalls, accounts, tracking or in-app purchases. Every timer mode and feature is available to everyone. Presets and workout history are stored locally and are not transmitted to us.

Simple utility apps should respect the people who use them. Clear Intervals is our small contribution to that idea.
