About this timer

Feel Best Intervals is an interval timer for HIIT and Tabata training. It opens on the classic Tabata pattern — 20 seconds of work, 10 seconds of rest, 8 rounds — and every value can be changed: prepare time, work, rest, rounds, sets and the break between sets.

Using it

• Set your numbers, or tap one of the quick patterns, then press Start.
• The screen fills with colour for each phase, so you can read it from across the room.
• Skip jumps to the next phase, Pause holds the clock, Reset returns to the start.
• Your settings are remembered on this device.

Sound

Three short beeps count into every phase change, a tone marks the switch, and a voice announces the phase and round. Cues are mixed over whatever you are already playing rather than stopping it. Both spoken cues and beeps can be switched off.

Screen and background

While the timer runs it asks the device to keep the screen awake. If the screen does turn off or you switch apps, the clock keeps its own time and comes back in the right place rather than drifting.

Train at your own pace and stop if something hurts. This app gives you a clock, not medical advice.
