About this app

SetBell counts your work and rest intervals out loud, so you can put the phone
down and train.

Set three numbers - how long you work, how long you rest, how many rounds - and
press start. The screen fills with colour, a bell marks every change, and the
display stays awake until you are done.

READY-MADE WORKOUTS
- Tabata - 20 seconds on, 10 seconds off, 8 rounds
- HIIT - 40 seconds on, 20 seconds off
- Circuit training - 45 seconds on, 15 seconds off
- Boxing - 3 minute rounds with 1 minute rest, 12 rounds
- Boxing (amateur) - 2 minute rounds, 3 rounds
- EMOM - every minute on the minute
- Strength sets - 45 second set, 90 second rest
- Stretching - 30 second hold, 10 seconds to change

Tap any of them to load it, then adjust anything you like. Your last timer is
remembered for next time.

BUILT TO BE GLANCED AT
- Red means work, green means rest, blue means get ready - readable from across
the room and mid-rep
- Big countdown with the round number under it
- A bell at every change, three beeps before it, and a vibration with each one
- A long triple bell when the workout is finished
- A progress bar showing how far through the whole session you are
- The screen will not sleep while the timer runs
