What's in the app

For clients and for the trainers who coach them, on iPhone, Apple Watch and the web. The iPhone app is in beta with a few gyms; your trainer gets you access once you're accepted.

Start in plain EnglishTell the app where you are right now, in your own words. Your trainer gets a first week drafted from it before you've finished setting up.

Gym, home or travellingEvery exercise has a trainer-approved alternate for home, hotel or bodyweight. Tell the app where you are and the plan adapts.

Works without signalLog sets in a basement gym or on a plane. Everything saves on your phone and syncs when you're back. The rest timer lives in the Dynamic Island, and Siri can start today's workout.

Apple Health, both waysWeight, body fat, sleep, water, heart rate, VO₂max and more flow in automatically once you approve each category. What you log in MinFit flows back to Health.

Live sessions, in the gym or virtualBook open slots from your trainer's real availability. Virtual sessions get a Zoom link automatically; in-gym sessions show where to meet. Calendar and reminders included.

Form checksRecord a set from inside the workout. Your trainer replies with comments pinned to the exact second.

Progress you can seeWeight and resting heart rate trends, measurements filled from your scale, before-and-after photos you choose to share, and next week's loads proposed from what you actually lifted.

Daily habits and check-insSteps, water, sleep and your own habits, ticked in a second. A two-minute check-in on Sunday that your trainer actually reads.

An AI coach that knows your planInstant answers about time, swaps and form. Anything about pain goes straight to your trainer.

Music for every sessionPlay your Apple Music playlist during workouts, or let MinFit build one for the session.

Optional leaderboardIf your gym turns it on, join with an alias. No real names, ever.

A QR code on the wallNew members scan your gym's code, create their own account with their phone and email, and land in your Requests with a first week already drafted. Accept in one tap. Cap it, expire it, or make a new one any time.

Templates and AI draftsSave a week as a template or let the AI draft one from a brief, apply it to any client, then personalise. Drag to reorder, type to add exercises.

Privacy

Apple Health data stays on your phone unless you choose to share it. You approve each category separately and can turn any of them off at any time. Only daily summaries and per-workout stats are ever sent, never raw heart-rate streams. Your trainer sees what you share and nothing more.
