Pace by Athlytic reads your Apple Watch health data and tells you what actually matters -- in plain language, not just charts and numbers.
Most health apps overwhelm you with scores, rings, and graphs. Pace takes a different approach. It monitors 35+ health signals, learns what's normal for you, and only speaks up when something is worth your attention.
HOW IT WORKS
Just wear your Apple Watch. Pace does the rest. No data entry required, no numbers to interpret. Each day, Pace checks your health data and gives you a clear summary of how you're doing.

SMART HEALTH INSIGHTS
Pace learns your personal baselines over 60 days, then alerts you when something shifts. Instead of showing you a number and hoping you know what it means, Pace explains it:
"Your heart rate variability is lower than usual"
"Your blood pressure trend is elevated -- the AHA considers this Stage 1"
"Your walking speed has declined -- this is one of the strongest predictors of overall health"
And when things improve, Pace tells you that too. No open loops -- when a concern resolves, you'll know about it.
HEALTH PATTERNS
Pace discovers correlations hidden in your data -- like how alcohol affects your HRV, or how daylight impacts your deep sleep. Every pattern is statistically validated and backed by peer-reviewed research. No guessing, no astrology.

YOUR PRIVACY
All analysis happens on your iPhone using Apple's on-device AI. No cloud uploads, no accounts, no tracking, no data selling. Your health data never leaves your phone.
I’ll admit I had some reservations at launch but the devs were incredibly responsive and fixed every minor gripe that I had. The app is quite good for seeing your health data quickly and easily.

I have been a longtime Athlytic user in combination with HealthFit. I stumbled across this new Athlytic app in the App Store. Pace is just right, your health monitor, I am really looking forward to getting to know this application.

So there is no way to contact the engine other than this, to correct wrong assessments. Or correct the course of recommendations. Seems short sighted or lack of support. I’ll keep people posted how it works out. The AI will refuse to correct actions and recommendations which seems really lame.
