- Apple Watch is here. Log sets from your wrist, control rest timers with the Digital Crown, and track cardio with live heart rate — even when your phone's in the locker. Streaks and your next workout are available as watch face complications. - Cardio, fully built out. Programmable interval workouts, live distance and heart rate, a persistent mini-player so you can navigate the app mid-run, and goals and trends to see where you're heading. Everything syncs to Apple Health. - Eat like you train. Scan a barcode, snap a photo, or just describe your meal — food logging now takes seconds. Macro visualizations show how nutrition connects to your training. Water and supplement tracking round it out. - A Progress tab worth opening. A redesigned four-tab layout with an estimated 1RM trend, a muscle recovery heat map, a multi-signal activity calendar, and side-by-side progress photo comparison. - Smarter workouts. Auto-generated workouts, progressive overload prompts, weight suggestions based on your last session, supersets, RPE tracking, and an exercise guide with demo images. - Your coach checks in. Proactive check-ins from your AI coach, plus gym and measurement reminders that arrive when they're useful. - Plus offline support so a bad signal never costs you a set, full data export and deletion, and a large number of bug fixes and performance improvements. - We've removed the money-staking feature to focus on the training experience.
