## What is Trainr?

Trainr is an interval timer built for real training: big digits you can read from across the gym, a clear color for every phase and sounds that push you on.

PICK A WORKOUT, HIT PLAY
• Tabata and Rounds are ready on first launch. Tap ▶ and go.
• Unlimited rounds: keep going until you stop. Trainr counts your rounds and your time.

BUILD IT BLOCK BY BLOCK
• Get Ready → Work → Rest → Rounds → Circuits → Recovery → Cool Down.
• Add only the blocks you need. Every change is saved as you make it.
• Exercise names rotate through the rounds.

MADE FOR THE GYM
• Huge digits in 00:00, 0:00.0 or 00:00.00.
• Seven training sounds: war gong, boxing bell, air horn, referee whistle, drums, electro and digital beep. Plus five calm sets for yoga and stretching.
• A sound for every moment: a double strike on the last round, rising clicks for the final seconds.
• Optional voice coach, flashlight flashes and vibration.
• Keeps running with the screen locked, with a Live Activity on the Lock Screen and in the Dynamic Island.

IPHONE DUO, IPAD AND APPLE WATCH
• iPhone Duo: hold it like a book, with the timer on one page and the controls and next phases on the other. Unfolded, your workouts sit in two columns around the hinge.
• iPad: the timer and the next phases side by side.
• Apple Watch: your workouts on your wrist, with haptics and heart rate.

ALSO
• A stopwatch with laps.
• Weekly streak and history. Save workouts to Apple Health if you like.
• No account, no ads, no tracking.
