Your watch already knows. Now it changes the session.
Sleep, HRV and resting heart rate from Apple Health or Health Connect, compared against your own trailing normal — and used to change what today’s session asks of you.

What goes wrong without it
Wearables produce a great deal of data and almost none of it changes anything. You get a score out of a hundred, you look at it, and then you do the session you were going to do anyway.
A readiness number that does not alter the program is decoration.
What the app actually does
With your permission, Train Smart reads sleep, heart rate variability, resting heart rate, workouts, heart rate, cardio fitness, energy, distance, steps and body mass from Apple Health on iPhone, or from Health Connect on Android. Each metric has its own switch — you can grant sleep and refuse everything else.
Those signals combine with how you say you feel and what you did yesterday into a readiness score. The score then does something: it scales the session. A genuinely poor day — short broken sleep, HRV well below your own baseline — reduces the working sets you are prescribed. A good day leaves them alone.
The comparison is always against your own trailing baseline, never against anyone else’s numbers. That is not a design preference; it is what the monitoring literature supports, and the papers are on our sources page.
The parts that matter
- Ten metrics, each with its own switch
- Sleep, HRV, resting HR, workouts, heart rate, VO₂ max, active and resting energy, distance, steps and exercise minutes, body mass. Nothing is read that you have not granted.
- HRV against your own normal
- A single day’s HRV reading means very little. A sustained drop below your own rolling baseline is one of the earliest signs you are carrying fatigue, and that is what the score responds to.
- Training-load warnings
- The app tracks your acute load against your four-week chronic load and flags a sharp climb — the pattern the IOC consensus statement associates with raised injury risk.
- On your home screen, only when it matters
- On an ordinary week there is nothing to see. When your load stands out against your own recent weeks, the first screen you open says so — with the reason in your own numbers, the eight weeks it was read from, and what to do about it this week.
- A manual answer always wins
- If you tell the app you feel fine, that beats what the watch inferred. The watch fills in when you have not answered, not over the top of you.
- No sync button
- Data arrives on its own rather than through a button you have to remember to press — on iPhone, through a live observer query. Sleep and Body Battery-style scores are computed here, because neither Apple Health nor Health Connect exposes them.
Is this you?
