Peak Score: Train or Rest

Peak Score: Your Daily Training Readiness for Apple Watch

Your Apple Watch captures your HRV, sleep, resting heart rate, and training load every single day.

The problem is it never tells you what to do with any of it.

You wake up, check your wrist, and still have no idea whether today should be a hard session or a rest day.

Peak Score answers that question before you even put your shoes on.

Now Peak Score also includes an on-device AI Coach that turns your daily readiness into specific training guidance. All coaching insights are generated on your iPhone and Apple Watch using on-device machine learning, so your Apple Health data never leaves your device for AI processing.


FEATURES

Daily Readiness Score
Know exactly what your body can handle today. Peak Score analyzes your Apple Watch data overnight and delivers one clear recommendation every morning: Rest, Easy, or Hard. No interpretation required. No charts to decode. Just the decision your body is actually ready for, waiting for you when you wake up.

HRV Tracking
Heart rate variability is the most reliable signal of how recovered your nervous system is after training, stress, or poor sleep. Peak Score reads your HRV from Apple Watch every night and uses it as the primary input in your readiness calculation, so your daily recommendation reflects how your body truly recovered, not just how many hours you were in bed.

Training Load Analysis
Most Apple Watch users see their training load number and have no idea what it means. Peak Score fixes that. Your 7-day load is compared against your 28-day baseline and returned as a single clear verdict: Too Low, Optimal, or Too High. If fatigue is accumulating faster than your body can absorb it, you'll know before it becomes an injury or a performance plateau.

Sleep Score
Inside Peak Score, sleep is not a wellness feature. It's a direct input into your training decision. A poor night shifts your readiness score the next morning, which can flip a planned hard session into an easy day. Understanding that connection, automatically and without manual logging, is what separates smart training from guesswork.

7-Day Readiness Trend
A single score tells you what to do today. The trend tells you where your training is actually heading. Watch your readiness climb as your body absorbs a training block, or catch a downward pattern before it turns into overtraining. Peak Score shows you recovery history, which is the variable that actually predicts your next performance.

Tomorrow's Readiness Prediction
Hard sessions need to be earned and timed. Peak Score tells you whether tomorrow looks like a day your body will be ready to push or a day better suited for recovery. Stack your hard efforts intelligently, protect your taper weeks, and stop making training decisions based on the calendar instead of your body.

AI Coach (On-Device)
The AI Coach takes your readiness, training load, sleep, and HRV and turns them into clear, actionable training guidance. It works entirely on your device using system-provided on‑device machine learning (Apple Intelligence where available). Your Apple Health data is not sent to our servers to generate these coaching recommendations, so you get smart guidance without giving up your privacy.

Who Peak Score is built for
Runners, cyclists, triathletes, and hybrid athletes. Athletes who are serious enough to track their data but frustrated that Apple Watch never tells them what to do with it. If you have been searching for a real training readiness app for Apple Watch, one that gives you a readiness score rather than another chart, Peak Score is built specifically for you.

Peak Score. Train with clarity. Avoid burnout.
