Spotter: AI Workout Coach

Your week, planned. Your coach, on-device. Spotter builds and tunes your training with Apple Intelligence — private, offline, and entirely yours.

Spotter is a weekly training planner with a coach built in — and the coach runs entirely on your iPhone.

THE WEEK IS THE PLAN Set up a recurring Monday-to-Sunday split. Every day knows its focus, its exercises, and how long it takes. Training days, rest days, one glance.

A COACH, NOT A CHATBOT Powered by Apple Intelligence, the coach builds your first plan around your goal, experience, equipment, and schedule — then reviews your workouts, watches your progress, and proposes changes you approve before anything is written. It runs on-device: no cloud, no account with us, and it works in airplane mode.

LOG WITHOUT FRICTION Big steppers, plate math for the plates you actually own, and a rest timer that lives on your Lock Screen and in the Dynamic Island — with +30s and Skip right on the island. Finish a session and get progression suggestions you can apply in one tap. Personal records get noticed.

DETERMINISTIC NUMBERS Weights are never AI guesses. Every suggestion comes from transparent rules and your own history, rounded to the increments your gym actually has.

YOUR DATA IS YOURS Everything lives on your iPhone and syncs through your private iCloud. Apple Health workouts and bodyweight are opt-in, and Health data never leaves your device. No ads, no tracking, no third-party analytics.

ALSO IN THE BAG • A library of 873 exercises with motion previews and step-by-step instructions • A weekly check-in that rolls your training week over • Training-day reminders that inform, never nag • Export everything as JSON, or delete it all, any time

Spotter offers general training guidance, not medical advice. AI coaching requires an iPhone with Apple Intelligence (iOS 26 or later); everything else works from iOS 18.
