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

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.
