TrainInsight
iPhone · Apple Watch
Understand your recovery. Plan your next session.
TrainInsight reads the sleep, heart and workout data your Apple Watch already records in Apple Health and turns it into one answer each morning: how ready you are, compared with your own normal, and what to do with it. Today gives you the score and the plan, Training shows whether your week is working, and Trends shows how your body changes over months.
Requires iOS 18 or later. The Apple Watch app requires watchOS 10 or later.
What it does
Readiness every morning
A 0–100 score from last night's sleep, HRV, resting heart rate and your recent training load, each compared with your own 30-day normal. Four bands — Primed, Ready, Easy and Recover — and Today shows what's shaping it.
A plan for today
The session that fits your readiness, with an effort target. After your first workout of the day, Live effort shows your effort against the target on the Lock Screen and in the Dynamic Island until midnight.
Body signals
Last night's wrist temperature, breathing rate, resting heart rate, HRV and blood oxygen against your 30-night normal. An optional morning alert tells you when two or more drift together.
Tonight's sleep plan
In the evening, Today suggests a bedtime from your sleep need and recent sleep debt, alongside last night's sleep. An optional wind-down reminder nudges you toward it.
Training that adds up
Plan your week, then see this week's load against it, your last 7 days against your 4-week normal, and an intensity mix in personal heart-rate zones set from your age or a max you choose.
Trends and a weekly report
Readiness, sleep, HRV, resting heart rate, VO₂ max and daily load over 7 and 30 days, or 90 days and a year with Plus. A weekly report sums up your week, with a card you can share.
What moves your readiness
Tag your day — alcohol, a late meal, travel, stretching, or tags of your own. With Plus, once there are at least five tagged days, see how each tag relates to next-morning readiness. Associations, not proof.
Coach, on your device
Ask about today's readiness and training. Coach runs only on Apple Intelligence's on-device model, on supported devices with iOS 26 or later, so your questions and numbers never leave your device.
Apple Watch
Today's score, plan and effort on your wrist, calculated on the watch from Apple Health, plus Readiness and HRV complications for your watch face.
Widgets, controls and Siri
A Readiness widget for the Home Screen and Lock Screen, a Last Night sleep widget, Readiness and Tag Your Day controls for Control Center, and Siri for your score, today's plan, sleep, workouts and tags.
TrainInsight Plus
Readiness, today's plan, body signals, the sleep planner, heart-rate zones, the weekly report, widgets, Siri and Coach are all included. TrainInsight Plus is an optional one-time purchase that adds 90-day and 1-year trends, what moves your readiness, a PDF health report, 7 more themes and 20 more app icons.
Privacy first
TrainInsight reads from Apple Health and calculates everything on your device. It never writes to Health. No account, no server, no analytics, no ads, no third-party SDKs, no tracking. Coach uses Apple Intelligence's on-device model, so your questions stay on your device too. The full story is on the privacy page.
Not medical advice
Readiness, plans, body signals and Coach are general fitness guidance, not medical advice. TrainInsight isn't a medical device and can't diagnose illness. If you feel unwell, listen to your body and talk to a doctor.
