What readiness actually means
Readiness helps you choose between a hard session, moderate load, and a lighter day.
Arry shows the score together with the factors under it: sleep, HRV, resting heart rate, and recent load.
Apple Watch collects the data; Arry shows which readings affected today's score.
Which signals matter
One reading is not enough, so Arry compares several measurements from Apple Health.
What Arry gives you
- A daily readiness score with its explanation.
- Apple Watch input without requiring another wearable.
- Sleep, HRV, resting heart rate, and recent load beside the score.
- A basis for adjusting today's training.
If you want the scoring logic, open the Arry methodology page. If you want the privacy model, continue to the privacy page.
How readiness changes today's plan
Use the morning score to adjust training before accumulated fatigue worsens a session or how you feel.
- High readiness: good day for a quality session or higher intensity.
- Medium readiness: keep volume and intensity moderate.
- Low readiness: reduce the load, extend warm-up, or shift the hard work.
Who this is for
Arry is for Apple Watch users who want to consider their collected data when planning load.
- people who want readiness guidance without buying another device;
- people who track HRV but know HRV alone is not enough;
- people who want recovery, sleep, and training load on the same screen;
- people who want core health data processed on their device.

Questions before installing
Why not just look at HRV directly?
Because HRV alone is incomplete. It makes more sense next to sleep, resting heart rate, and recent load.
Does readiness mean the same thing as recovery?
They are related. Recovery describes your state; readiness indicates whether to change today's load.
Is this useful if I train and also care about work stress?
Yes. Readiness is relevant whenever sleep debt, stress, and recent load affect how hard you should push, whether that pressure comes from training or from daily life.
