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. Choose from 16 workouts and 6 sets, each with instructions on how to do it • Set up your own workout once: rounds, work time and rest time. Then start it with a single tap • With workout sets, chain your warm-up, main workout and stretching into one session that runs by itself from start to finish • Got a workout from your coach or a friend? Add it from a link or QR code ALWAYS KNOW WHAT TO DO • 116 exercises with photos and how-to instructions, including dumbbell, kettlebell, resistance band and pull-up bar moves • Mid-workout, tap the exercise name to see how it's done • Add a note to your workout, like tips from your coach, and see it while you train • Working each side separately, like in yoga? Sides mode times the left and right side for you WITH OR WITHOUT APPLE WATCH • Control any workout from your wrist: see your heart rate, heart rate zones and calories live on your watch and iPhone • Pause and skip right from your watch, even with a double tap • No watch? AirPods Pro 3 and Powerbeats Pro 2 can show your heart rate too (iOS 26) • Workouts are saved to Apple Health SEE YOUR PROGRESS • After every workout, a chart shows your heart rate and heart rate zones during work and rest • Weekly summaries and a weekly streak help you make training a habit. One workout a week keeps your streak alive • Show off your result: a ready-made card with your own photo for a story or post MAKE IT YOURS • Light, dark or automatic appearance • Widgets for the Home Screen and Lock Screen • Works on iPhone, iPad and Apple Watch ARES PLUS—EVEN MORE • Workouts that change as you go: set the shortest and longest time, and Ares lays out the intervals for you—getting longer, getting shorter, or with shorter and shorter rests. No need to set each one by hand • A different exercise in every interval, like squats, then push-ups, then a plank. The voice announces each one, so you don't have to remember the order • Train without your iPhone: save your workouts to Apple Watch and leave your phone at home or in your locker • Record exercise names or cues in your own voice and hear them during your workout • Extra themes, coach voices and sounds, including the Calm voice for yoga and stretching • Access for your whole family with Family Sharing Privacy Policy: https://ares.eris.one/privacy-policy/ License Agreement (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
