The athlete app has become the daily operating view for training.

Today, from your coach screen in the Matter athlete app

Today, from your coach

Home

The session your coach assigned leads your Home screen, with the reason behind it. Start it, read the steps, or ask the AI coach about it. Readiness, recovery, strain and sleep sit underneath.

Readiness

Readiness is scored against your own 30-day baseline, not a population average. Recovery, strain and sleep each show where you sit against your usual range, and today’s read says what to do with it.

Strain

Day strain is scored against your productive range. When you have overreached, Matter says so and why. When there is not enough data to say, it says that instead of filling the gap with a number.

Timed

AMRAP, EMOM, For Time, Tabata, Intervals and Circuit blocks run in a full-screen timer that shows the round, the phase and what comes next. Your block score is saved and sent to your coach with the session.

Plan

The week your coach wrote sits beside the work you have already done. Every session your coach writes is tagged, and you check it off as you finish.

The strength logger carries the coach’s prescription, your last time, and a rest timer. When you finish, the summary shows new records, what changed against the plan, and sends it to your coach.
