FitnessKit is the operating system for personal trainers. An on-device AI drafts every client touchpoint — check-in replies, progress reports, form cues, the next step for each person on your roster — and you approve them in one queue. That's hours back every week, and the capacity to coach more clients without working more hours. Every client you bring on gets a premium training app of their own, free. PRIVATE, ON-DEVICE AI Every draft, insight and readiness score is generated on device using Apple's Foundation Models. It works offline, and your clients' training data never leaves the phone to be processed. THE APPROVAL QUEUE • One place to sign off everything your AI drafted, instead of chasing it across a dozen screens • Drafted check-in replies you can edit inline before they send • Monthly progress reports written for each client, ready for your co-sign • Form cues pinned to the exact rep that needs them • A proposed next step for every client who needs one • Flows earn autopilot only after you've approved their drafts untouched — the AI graduates, you don't gamble • Teach it your Coach Voice so the drafts already sound like you YOUR ROSTER, AT A GLANCE • Every client in one list, filtered by who's at risk or needs attention first • Engagement and adherence per client, so nobody quietly drifts away • Per-client AI readiness from recent training, sleep and recovery • Real-time compliance charts across every active program • A notification the moment a client finishes an assigned session, with full stats PROGRAMS BUILT ONCE, ASSIGNED IN SECONDS • Build multi-week programs with per-day workouts and progression rules • Keep templates in your library and fork a working copy per client • Assign straight into a client's schedule, or customise the start date and add a note • Already have programs elsewhere? Paste them in and the AI rebuilds them week by week AUTOMATE THE BUSYWORK • Automation flows: a trigger, then a sequence of steps that run themselves • Recurring check-ins that go out on your cadence and come back structured • Onboarding that runs itself the moment a new client connects SESSIONS THAT SCHEDULE THEMSELVES • Publish your availability and let clients book the slots that suit them • A week view of everything booked, with cancellations and no-shows tracked • Two-way calendar sync so your sessions live alongside the rest of your day WHAT YOUR CLIENTS GET • Their assigned programs and workouts, ready to train • Log every set with reps, weight, duration and RPE as they go • Set types, rest timers and live progress through every session • Home Screen widgets and a Live Activity showing the set and rest timer on the Lock Screen • 1:1 chat with you — answers, form cues and check-ins in one thread • Record a lift and get a form score with the cues that matter • A monthly progress report they can actually share A HUGE EXERCISE LIBRARY • Hundreds of exercises with video demonstrations and step-by-step instructions • Filter by muscle group, equipment and exercise type • Add custom exercises with the metadata that matters • Per-exercise progress charts to watch strength climb over time • HealthKit integration for heart rate and calories, and post workouts back to HealthKit WHO IT'S FOR Personal trainers coaching clients remotely, gyms running a floor of trainers, and anyone who wants their coaching to scale further than their calendar does.
