Glance at your Lock Screen to see how much is left. PLAYS WITH YOUR MUSIC Your music keeps going at its own volume. The announcements come over the top. FREE No account. No subscription. No full-screen ads. ABOUT TABATA Twenty seconds of work, ten seconds of rest, eight rounds, after a short warm-up. Devised by Professor Izumi Tabata at Ritsumeikan University, and used for squats, exercise bikes, running and much else. Maximum effort in each round is the point: a few minutes is said to do the work of far longer. Every duration is adjustable, so it does a great deal more than Tabata.
