Ranked by how hard the efforts are, how short the rests, and how much there is in total.
How the beeps work
Three short beeps, one per second, count you into every work round, then a long high beep: go.
Three short beeps count you out of every work round, then a long low beep: stop.
Turn the phone's media volume up; the beeps are high-pitched so they carry over music and traffic.
Heart rate (optional): tap ♥ at the top of this screen, or beside the dial during a timer, to connect a Bluetooth strap or watch that shares heart rate (Polar, Garmin, Wahoo, Coospo and most others). Needs Chrome or Chromium on Android or a computer, or Bluefy on iPhone and iPad. Readings are only shown, never saved or sent.
The screen stays on while a timer runs. Add Rounds to your home screen and it works offline.
