LoopBell is a small, single-purpose timer: it rings on a schedule you set, and it does that one thing well. No account, no app download, no dashboard full of features you'll never touch — just a bell you can trust to go off when it's supposed to.
Most timer tools try to be everything at once — habit trackers, project managers, social features bolted onto a stopwatch. That's often more than a workout, a study session, or a batch of cookies actually needs. LoopBell was built to be the opposite: open the tab, set a number, press start, and get out of the way. The Interval Timer repeats a sound at a fixed gap for as long as you're running it; the Pomodoro mode cycles focus and break periods automatically so you don't have to babysit it.
Everything runs client-side in your browser. There's no backend logging your sessions, no account system, and no settings synced to a server — the timer math and the sound generation both happen locally using the Web Audio API. See the Privacy Policy for the specifics on what third-party advertising cookies apply.
LoopBell is supported by a small amount of display advertising, placed to stay out of the way of the actual controls. There's no premium tier, no paywall, and no plan to add one — the goal is a tool that's still here and still free the next time you need it.
