The engine
Your watch knows what you won't admit.
Sleep, resting heart rate, load: MatchGrit reads your recovery data and adapts training – before tired becomes injured.
Sound familiar?
Ambitious players train past their own bodies too often. Bad sleep, elevated resting heart rate, heavy legs – noticed, then ignored. Until the body makes the decision for you.
Recovery as the planning baseline
Every morning MatchGrit reads your recovery values: sleep duration and quality, resting heart rate, recent load. That becomes your readiness score – and it decides what's on today. Intervals at 31% recovery? Not with this coach.
Apple Watch, Galaxy Watch, WHOOP
MatchGrit connects to the major platforms – Apple Watch via HealthKit, Samsung Galaxy Watch via Health Connect, WHOOP via the official API. No new device needed: use what you already wear.
The load guardian
Over weeks the AI maps your load curve: when are you building, when do you need a deload? Before tournament weeks this becomes critical – the guardian warns you before you show up overtrained in the most important week of the year.
Honest, not comfortable
Other apps celebrate you for grinding. MatchGrit tells you when 20 minutes of mobility beats 90 minutes of hitting. Not because the coach is nice – because the data says so.
What it looks like in the app
MatchGrit
Recovery 31%. Sleep 5:40 h, resting HR +8. No intervals today. Mobility, 20 minutes. Non-negotiable.
You
But I feel fine.
MatchGrit
Your nervous system disagrees. Matchplay is tomorrow – save today, win tomorrow.
Preview – design may change
FAQ
Which wearables are supported?
At launch: Apple Watch, Samsung Galaxy Watch and WHOOP. More to follow – Garmin is on the roadmap. Brand names are descriptive only; MatchGrit is independent of the manufacturers.
Does MatchGrit work without a wearable?
Yes. You'll get recovery questions (sleep, fatigue, soreness) instead of sensor data. Less precise, but far better than nothing.
What happens to my health data?
It stays tied to your account, is never sold and is used only for your training planning. Details in the privacy policy.
