Ares is an interval timer you don't have to keep looking at. A voice coach counts down the time, tells you which exercise is up and when to rest, so you can stay focused on your workout. Great for HIIT, Tabata, EMOM, AMRAP, circuit training, yoga and stretching—at home, at the gym or outdoors. No ads and no account needed. TRAIN WITHOUT WATCHING THE SCREEN • The voice counts down the final seconds and tells you what's next, so your phone can stay on the floor • Your music keeps playing, and if you want, Ares turns it down while the voice speaks • Work and rest have different colors, and the big numbers are easy to read from across the room • Keeps running with the screen locked: the timer shows on the Lock Screen and in the Dynamic Island, and you can pause without unlocking your phone START IN SECONDS • Pick a ready-made workout, like Tabata, HIIT 40/20 or stretching, and go.
