What Vytalio actually delivers

Built for users who feel overloaded, with concrete outputs from existing Apple Watch and iPhone signal data.

Four daily scores

Stress, Readiness, Sleep, and Energy with a compact zone model so you know what to change now.

  • Stress: Restored, Optimized, Pressured, Overload
  • Readiness: recovery score from 0 to 100
  • Sleep: quality from duration, efficiency, and depth
  • Energy: trajectory and fatigue carry-over

One action, two moments

The app gives practical direction for now and for evening wind-down, based on your current context.

  • Today action: short, specific, low-friction
  • Evening action: recovery-oriented recommendation
  • Everything stays tied to signal changes, not generic advice

Apple-first, on-device processing

HealthKit inputs are processed on your ecosystem first; no third-party ads and no raw-health resale.

  • Raw health data is not sold or used for ad targeting
  • Score and coaching logic run on-device by default
  • Clear data handling in Privacy and Terms

Trust contract

Core promises reflected in your app experience and legal pages.

On-device by design

HealthKit processing and score calculation happens on your iPhone.

Never sold

We do not sell health data and never use it to target ads.

Built on your data

Uses HRV, sleep, and activity directly from your Apple ecosystem.

Four signals. One clear picture.

Each score is calculated from Apple HealthKit inputs and designed to guide what you do next.

Stress

Restored → Optimized → Pressured → Overload

Signals from HRV, resting heart rate, load, and recovery patterns indicate overload risk.

Readiness

Scored 0 to 100

A readiness score for choosing workload, pacing, and rest before your next push.

Sleep

Duration, efficiency, and depth

Sleep duration, deep/rest phases, and continuity collapse into a practical readiness context.

Energy

Your battery for the day

Tracks when stress and fatigue accumulate so you know your most effective capacity window.

See stress change, not just a score.

Vytalio maps pressure across the day so peaks, recovery, and the effect of a reset are easier to understand.

Sample day

Stress across your waking hours

Measured Estimated
Illustrative daily stress chart Stress starts restored at 22, rises through the morning, peaks at 82 in overload, falls to 44 after a reset, rises again during the afternoon, and finishes restored at 26. The values are illustrative.

Pressure peakStress reached 82 in the late morning.

Recovery after resetThe signal returned to 44 after a short reset.

Beyond daily scores.

Vytalio connects today's signals to longer-term pace, movement patterns, and the choices that can change what comes next.

Bio Age

Your signals, expressed as age.

Compares biological and chronological age using HRV, resting heart rate, sleep, activity, and confidence in the available data.

HRV RHR Sleep Activity
Death Clock

A deliberately blunt view of your projected runway.

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.

Sedentary Intelligence

Movement measured across your waking day.

Stand hours, steps, exercise, and movement are combined to distinguish active time from long sedentary stretches.

Life Pace

See whether today's behavior is helping your long-term pace.

Vytalio learns your baseline before making stronger calls, then explains the main driver and your next move.

Recovery Debt Accumulated load that still needs to be paid down.
Optimal Times Windows for focus, movement, meals, and wind-down.
Movement nudges Timely prompts to stand, walk, or take a light reset.

The watch you're already wearing. No extra hardware: Vytalio reads the heart rate, HRV, sleep, and motion data your Apple Watch already records.

Coaching that stays on your phone.

When your signals shift, Vytalio suggests one clear action for now and one recovery move for later.

  • Simple language: no dashboard fatigue.
  • Same logic for every session: signal first, context next.
  • Apple devices and HealthKit data only.

Today
Readiness is strong, but sleep depth dropped. Add a 20 minute walk and keep the evening caffeine off.
Done. I will walk after lunch and stop caffeine by 2 p.m.

How Vytalio works.

Three moments. No setup wizard.

1

Read the signal

Your scores are updated from the data your watch already records.

2

Choose one action

Each check-in returns a single practical action with an expected effect.

3

Track the result

Watch the change in your readiness and adjust your plan next check-in.

Frequently asked questions.

Answers for people who want to act, not speculate.

Does Vytalio use cloud AI or send health data away?
No. Coaching and score logic run on-device by default. Raw health data stays in your Apple ecosystem and is not sold.
Can I use Vytalio without an Apple Watch every day?
Yes. Scores are still useful with partial data, and the app clearly shows limits when signals are incomplete.
Is Death Clock a medical prediction?
No. It is a deliberately blunt estimate based on age and current Life Pace. It is not medical advice, and the projection changes as your health signals change.

Your signals are about to become clearer.

Vytalio is coming soon to iPhone and Apple Watch.
