Tabata Timer
Run the classic 20-seconds-on, 10-seconds-off Tabata protocol with spoken cues for every round — no need to watch the clock.
Tabata is one of the most effective four-minute workouts there is: eight rounds of 20 seconds of maximum effort separated by 10 seconds of rest. The intervals are short and unforgiving, which is exactly why an accurate, audible timer matters — you cannot afford to glance away to check how long is left. Voice Timer announces each work and rest phase out loud so you can give every 20-second burst your full effort.
The classic Tabata structure
20 seconds of all-out work.
Repeat 8 times — that is one 4-minute Tabata block.
Rest 1 minute, then start the next block if you are stacking rounds.
Build it in seconds
In Voice Timer, create a work interval of 20 seconds and a rest interval of 10 seconds, group the pair into a loop, and set it to repeat 8 times. Want a longer session? Wrap several Tabata blocks in an outer loop with a rest between them. Save it as a preset and it is ready to run again with one tap.
Hands-free and offline
Voice guidance calls out the current interval, the next one, and the countdown, with adjustable rate, pitch, and volume. Core timing runs entirely on-device, so your Tabata keeps going even with the screen locked or no connection. You can also export the whole session as an MP3 to play through any speaker.
Frequently asked questions
What is the Tabata protocol?
Tabata is a specific HIIT format: 20 seconds of all-out work followed by 10 seconds of rest, repeated 8 times for a total of 4 minutes. It comes from research by Dr. Izumi Tabata. Voice Timer has this structure ready to build in seconds.
How long is one Tabata?
One Tabata block is exactly 4 minutes: eight rounds of 20 seconds work and 10 seconds rest. Many people stack several blocks with a rest in between, which you can set up as repeating loops in Voice Timer.
Can I change the 20/10 timing?
Yes. The classic Tabata is 20s on / 10s off, but Voice Timer lets you adjust the work and rest to any length and change the number of rounds, so you can scale the intensity up or down.
Does Voice Timer count the rounds out loud?
Yes. Voice guidance announces each work and rest interval and the round number, plus a spoken countdown, so you can keep going without looking at the screen.
