What is TimerTrain?
TimerTrain is a free online timer that lets you chain multiple timers together — like train cars — and play them in sequence, over and over. No install, no sign-up. Open the page, press play, and use it as a sequential timer, interval timer, or repeating multi-timer right away.
How to use it
Tap "Add timer" to line up as many timers as you need, tap the time to edit it, and give each one a name and a color. Set how many rounds to repeat and press start — your work/break or exercise/rest cycle keeps running automatically. Share your exact setup with anyone by simply copying the URL.
Perfect for
Pomodoro sessions (25 min work + 5 min break), HIIT and Tabata workouts, studying and classroom activities, cooking multiple dishes, presentation practice — any situation where you need several timers to run one after another.
