What’s new
Version 2.0.7 · Updated October 10, 2026
This one's all about the moment you finish, and getting started faster. • A finish screen that knows your workout — The headline now reflects what you actually did, like your first full finish, a new personal best or a streak • A cleaner Home on iPhone — Timer cards are now wide, so you can see the time, steps and sets at a glance • Start sooner — The countdown before your first exercise is now 3 seconds. Prefer it longer? You can change it anytime in Settings • A more lifelike Jump Squat — The animation is now based on real motion • Apple Watch and iPhone, reliably in sync — Ending a paused workout on Apple Watch now always stops your iPhone timer too • Little touches throughout — Long preset names fit neatly, and button text is easier to read in every color
