Don't stress. Vytalio is almost here.
Vytalio reads your Apple Watch and iPhone HealthKit data and turns it into practical direction for the next hours. Everything happens on-device, and the signal updates with your changing load.
Built for users who feel overloaded, with concrete outputs from existing Apple Watch and iPhone signal data.
Stress, Readiness, Sleep, and Energy with a compact zone model so you know what to change now.
The app gives practical direction for now and for evening wind-down, based on your current context.
HealthKit inputs are processed on your ecosystem first; no third-party ads and no raw-health resale.
Core promises reflected in your app experience and legal pages.
HealthKit processing and score calculation happens on your iPhone.
We do not sell health data and never use it to target ads.
Uses HRV, sleep, and activity directly from your Apple ecosystem.
Each score is calculated from Apple HealthKit inputs and designed to guide what you do next.
Restored → Optimized → Pressured → Overload
Signals from HRV, resting heart rate, load, and recovery patterns indicate overload risk.
Scored 0 to 100
A readiness score for choosing workload, pacing, and rest before your next push.
Duration, efficiency, and depth
Sleep duration, deep/rest phases, and continuity collapse into a practical readiness context.
Your battery for the day
Tracks when stress and fatigue accumulate so you know your most effective capacity window.
Vytalio maps pressure across the day so peaks, recovery, and the effect of a reset are easier to understand.

Vytalio connects today's signals to longer-term pace, movement patterns, and the choices that can change what comes next.
Compares biological and chronological age using HRV, resting heart rate, sleep, activity, and confidence in the available data.
Age and Life Pace shape a dynamic horizon, while the app shows which daily signals are helping or accelerating the estimate.
Not medical advice. Estimates update as your health signals change.
Stand hours, steps, exercise, and movement are combined to distinguish active time from long sedentary stretches.
Vytalio learns your baseline before making stronger calls, then explains the main driver and your next move.
The watch you're already wearing. No extra hardware: Vytalio reads the heart rate, HRV, sleep, and motion data your Apple Watch already records.
When your signals shift, Vytalio suggests one clear action for now and one recovery move for later.
Three moments. No setup wizard.
Your scores are updated from the data your watch already records.
Each check-in returns a single practical action with an expected effect.
Watch the change in your readiness and adjust your plan next check-in.
Answers for people who want to act, not speculate.
