GLANCEABLE & MULTITASK-READY A large timer ring shows your remaining time at a glance—green for action, blue for break.

We were tired of interval timer apps that lock basic features behind subscriptions. So we built one that gives you everything—for free. No premium tiers. No "free trial" that expires. No data sold to advertisers. IntervalFree is maintained by a small team who believes great tools should be free. If it becomes part of your routine, you can support us with a voluntary coffee—but there's absolutely no pressure. Perfect for HIIT, Tabata, circuit training, boxing rounds, stretching, meditation, or any activity that uses timed intervals. Requires iOS 17.0 or later. Works on iPhone and iPad.
