Layrd: AI Workout Reviews
On-device review, every run
Free · Designed for iPad. Not verified for macOS.
Your workout, reviewed on your phone. Never on a server. Run, ride, or swim — Layrd reads your wearable and tells you what actually happened. No subscription.
Your workout, reviewed. On your phone. Never on a server.
Layrd reads your wearable and tells you what actually happened in your last session — the effort, the form, the cost. No coaching. No motivational copy. Just the numbers your watch collected, explained.
WHAT YOU GET
— A written review of every workout, generated on your iPhone in seconds. Run, ride, or swim.
— A cardio score that reflects what you did, not what an algorithm assumed about you.
— Running form analysis: cadence, vertical oscillation, ground contact time, stride length — read against the literature.
— Training load tracking with TRIMP, so you can see when you're loading and when you're digging.
— Sleep and recovery context pulled from HealthKit, alongside the session it affected.
— A home-screen widget for the score and the load at a glance.
BUILT ON REAL SCIENCE
Training load uses banister's TRIMP. Running form draws on heiderscheit's cadence research and daniels' pacing tables. RPE is computed against percent-of-max heart rate, not heart rate reserve. The methods are public, the math is on your device, and nothing here is invented marketing.
PRIVACY IS THE PRODUCT
No backend. No third-party SDKs. No analytics. No account.
Your workouts never leave your iPhone. The review runs on Apple's on-device foundation models — the same hardware that runs your keyboard predictions. We can't see your data because we never receive it.
COMPATIBILITY
Requires iOS 26 and a smartwatch that records workouts to HealthKit on your iPhone.
