Your AI drafts every client reply, check-in and progress report. You approve them in one queue — and get hours back every week to coach more people.
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.
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
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.
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.

I can add reps to any workout I have started the same or any previous day. I can do this all throughout the day without losing what I’ve already tracked. At the end of the day or any other day I can complete a workout whether I completed it or not. The goal is to complete them all, but in reality it just ain’t like that. I appreciate this flexibility.
Great for a free app but needs some fixes

This app is great as a workout tracker but needs some fixes. The first issue is the ram usage. I can’t verify that the app uses too much ram but based on the behavior I have a feeling it does. Apps are normally closed by IOS in the background once it takes up too much ram. This causes timers to reset at moments. Please take a look at the apps ram usage or anything that might be causing it to crash in the background. The second is the over reliance on a network connection. This is especially hard in gyms either bad connectivity or slow wifi networks. The third issue I have is the app doesn’t have an auto workout end. For example if I forget to finish a workout, it keeps it going indefinitely. It should have an auto finish feature. The last thing is that I think the interface would be better if reps and weight could be adjusted from the same screen where you click the check mark for the workout.
Best Fitness App Ever!
Mehhhhhhhhhhz
Easily the best, most intuitive, and feature-packed app in the fitness genre. I’ve used Strava, Map My Run, Garmin, FitBit, StrongLifts, and many more fitness and exercise-centered apps. This is my absolute favorite. The workout-building interface has done away with ever needing to return to spreadsheet workout tracking too! Love it.
Super helpful and free!
.101.1-
Great app, free has many work outs and allows you to add your own and track them. Honestly just what I was looking for
• New: the Approval Queue — every AI-drafted check-in reply, progress report and form cue in one place to sign off
• New: automation flows that run a sequence of steps from a trigger, plus recurring check-ins on your cadence
• New: session booking — publish your availability, let clients book, and sync it to your calendar
• New: monthly AI progress reports for each client, ready for your co-sign
• New: record a lift and get a form score with cues pinned to the rep that needs them
• New: paste in programs you built elsewhere and have them rebuilt week by week
• Autopilot now has to be earned — a flow only runs itself after you've approved its drafts untouched
• The trainer's shell is now a coaching console: Today, Clients, Business and Studio
• Fixed stale client data on the first session after signing in
