PeakRoutine — Your AI biomarker coach for Apple Watch

Your Apple Watch knows more about your body than your doctor does. Every day it captures your heart rate variability, sleep stages, resting heart rate, blood oxygen, respiratory rate, VO2 max, training load, recovery time, and dozens of other signals — silently building the most detailed health record any human has ever had access to.

And then it does almost nothing with it.

That gap is why we built PeakRoutine.

PeakRoutine is an AI-powered biomarker coaching app that turns the raw data sitting inside your Apple Health into specific, personalized, daily recommendations you can actually act on. Not generic "get more sleep" advice. Not another dashboard with prettier charts. Real coaching, grounded in your data, your trends, your recovery patterns — delivered in the language of action, not analytics.

How it works

PeakRoutine continuously analyzes 25+ biomarkers from your Apple Watch and iPhone: HRV, sleep architecture, resting and walking heart rate, VO2 max, training load, recovery time, mindfulness minutes, nutrition signals, and more. Our AI engine looks for patterns across these signals — the kind of correlations no single metric reveals on its own — and then tells you what to do about them.

A few examples of what that looks like in practice:

• "Your HRV has dropped 18% over the last four days while your sleep stayed flat. Skip the heavy lifting today — your nervous system is asking for a recovery session."

• "Resting heart rate is trending up for the third week in a row. This usually correlates with poor deep sleep. Let's look at your evening routine."

• "You're in a primed state today — HRV peak, full recovery, sleep debt cleared. This is a green-light day for the hardest workout of your week."

It's the kind of guidance you'd get from a $300/hour performance coach who knew your body intimately — except it lives in your pocket, adapts in real time, and costs a fraction of that.

Who it's for

PeakRoutine is built for the audience that every general fitness app has underserved: the performance-minded Apple Watch user. The person who already tracks HRV. The person who's tried Athlytic, Bevel, Welltory, Training Today, or Heart Analyzer and hit the same wall every time — good data, no direction. If you've ever stared at a dropping HRV chart and thought okay, but what do I do? — that's the question PeakRoutine exists to answer.
