What’s new
Version 2.0.2 · Updated September 9, 2026
• Your coach is the front door — Flexion opens on the conversation now. Ask what to train today or check what you lifted last week: one thread instead of four tabs. • Form check, in the conversation — Send a video of your lift straight into the chat and get the breakdown back in the same thread. No separate screen. • Log sets as you lift — Weight and reps go in from inside the workout itself, so the number you hit today is waiting the next time that lift comes up. • Progress you can ask for — Volume, muscle balance, personal records, recovery: ask, and the chart comes back in the thread. Apple Health now feeds it alongside Oura. • Bodyweight goals — Log your weight, set a target, and your coach trains you toward it. • A coach that picks its own depth — Quick questions get quick answers, harder ones get a deeper model. Pin one yourself if you'd rather choose.
