IT UNDERSTANDS HOW COACHES WRITE • Rounds, circuits, EMOMs, AMRAPs, and for-time caps • Per-side exercises run both sides, with time to switch • "Rest as needed" waits for your tap • When a message has several sections, you pick the one to run IT ASKS BEFORE IT ASSUMES • A range like 8-12 becomes a one-tap choice • A missing detail becomes a question you answer in seconds • Anything estimated is marked so you can check it before you start BUILT FOR THE GYM FLOOR • Spoken cues name every exercise, so you can leave the phone in your pocket • Countdown beeps in the last seconds of each interval • Your music keeps playing while the cues dip in and out • Automatic transition time between stations • Rep-based sets hold until you tap done ON YOUR WRIST • Start, pause, and skip from Apple Watch • The current interval and time at a glance • Runs alongside an Apple Workout session, so your rings and heart rate still count A PHONE CALL WON'T RUIN YOUR SESSION • The clock keeps running through the call • After a short call, it catches you up out loud • After a long call, the workout waits exactly where the call caught you FROM TEXT TO TIMER • Paste from Messages, Notes, or email • Dictate a workout; transcription happens on your device • The numbered format most coaches use works offline, and everything else gets an on-device draft you can check No account.
