Daily readiness and recovery state
Readiness score app
Readiness Score App for Sleep, HRV & Training
A useful readiness score should not be a mystery number. Gearstack Health is designed to show the signal, the context and the practical next step in one calm daily view.

What flows into the score
The readiness score condenses the signals that actually change a day: last night’s sleep in duration and quality, heart rate variability and resting heart rate against the personal baseline, and the training load of the previous days. Each ingredient is visible on its own, so the score never becomes a black box. When it drops, the user sees whether the short night, the elevated pulse or the dense training week is responsible.
One score, readable reasons
A score is only useful when users understand why it changed. Gearstack Health keeps the explanation to a few readable lines tied to recent sleep, recovery and activity, phrased in plain language instead of jargon. Over weeks this becomes the real product: users learn which of their habits move the score, and the morning glance replaces guesswork about how hard today should be.
Measured against your own baseline
Sleep need, HRV level and resting heart rate differ enormously between healthy people, so the score compares every value with the user’s own normal range of the past weeks. An 80 does not mean better than a friend’s 75; it means clearly above your own usual state. That framing keeps the number honest for beginners and for trained athletes alike, and it prevents the discouraging comparisons that make people quit tracking.
Training by daily state
The practical use is simple: place hard sessions on days that carry them, and keep easy days genuinely easy. A high readiness morning is the moment for intervals, heavy lifts or a long run. A low morning after two short nights favours technique work, easy movement or rest. The app suggests the direction and leaves the decision with the user; a plan that ignores how the body arrived at the day is just a calendar.
For athletes, everyday training and whole squads
Runners use the score to protect easy days, footballers to arrive fresh at match day, people with demanding schedules to place training where it fits. For clubs the same logic will scale up: the team dashboard planned as the S4E research project (start 2027 at the earliest) will show the readiness of a whole squad against each player’s own baseline, so coaches see before training who needs attention today.
Launch version and wellness framing
The first public version focuses on the core loop: morning state, recovery context, training areas and the daily briefing. More depth follows real usage. The score describes general wellness and supports habit decisions; it is not a diagnosis and does not replace medical advice, examination or treatment.
