Chained Timers ⏱️

The interval forge: a small, fast, installable PWA that sequences timers into named chains. Built for sport, breathwork, cooking, and study.

Standard smartphone timers only let you set one countdown at a time. Stopwatch apps force you to manually reset between intervals.

Chained Timers chains countdown segments together sequentially, vibrating and announcing segment transitions automatically:

Sequential Countdown Chains: Build custom interval sequences (e.g. HIIT workouts, Wim Hof / box breathing, multi-step tea brewing, Pomodoro cycles).
Audio & Haptic Alerts: Clear beeps, text-to-speech cues, and distinctive vibration pulses signal every interval boundary.
Offline & Installable PWA: Runs offline with zero latency and instant start once installed to your home screen.
Native Android Shell: Foreground service execution ensuring background accuracy even with the phone locked in your pocket.
