## What is Simple Timer?

More than a timer — a training partner. Simple Timer AI structures any interval workout with smart voice coaching and heart rate zones that adapt to your effort, so every cue lands at exactly the right moment.

Build multi-round sessions from any combination of work, rest, warmup, cooldown, meditation, and strength steps. Set durations in seconds or minutes, connect a Bluetooth heart rate monitor to assign zones per step, and let the engine handle every transition, countdown beep, and coaching cue automatically.

On iPhone, Live Activities bring your progress to the Lock Screen and Dynamic Island. Audio routes to AirPods, a speaker, or your car.
