How PeakState reads your day, charts your energy and steps in at the right moment.

From data to decisions in three steps.

  1. 01

    Connect

    Grant access to Apple Health, your calendar and screen time. Everything is processed with privacy first.

  2. 02

    Understand

    PeakState builds your personal energy model and forecasts how your energy will move for the rest of the day.

  3. 03

    Act

    Get timely, specific guidance — when to focus, when to rest, and which of the 14 tools to reach for.

Grounded in sleep and performance science.

PeakState doesn’t guess. Its model is built on established research in human energy regulation.

Circadian Rhythm

Your alertness follows a built-in biological clock. PeakState aligns your schedule with it instead of fighting it.

Sleep Pressure

The longer you’re awake, the more recovery you owe. PeakState tracks this balance so you can rest before fatigue piles up.

Heart Rate Variability (HRV)

HRV reflects how your nervous system handles stress and recovery. PeakState reads it as an early signal — so you can adjust before you crash.

Questions, answered.

Which devices are supported?

PeakState runs on iPhone with iOS 17.6 or later. Apple Watch data is read automatically through Apple Health — no separate setup needed.

Is my health data uploaded to your servers?

Yes. Health data you authorize is uploaded over an encrypted connection to our servers in Singapore and linked to your account, so we can generate your energy analysis, briefings, and alerts. It is never sold or used for advertising. If you turn on AI Data Sharing, summaries are also sent to our AI providers, Anthropic (US) or DeepSeek (China), to personalize AI features. You can delete your account and all your data on our servers at any time.

How much does it cost?

PeakState is free to download. After you sign up, a membership is required to use the app. Choose a monthly or annual subscription — both renew automatically and include a 1-week free trial for new subscribers. Membership unlocks the full app, including unlimited AI chat, unlimited 7-day energy experiments and an in-depth weekly report. You can cancel anytime in your App Store settings; to avoid being charged, cancel at least 24 hours before the trial or current period ends.

What data does PeakState need?

With your permission: sleep, heart rate, HRV, steps and workouts from Apple Health; calendar time slots (we never upload meeting titles, attendees, locations or notes); Screen Time, shown only in the app; and your approximate location for weather and pollen. Each permission is optional. If a night has no sleep record, the times your phone was in use that night (never app names) may be sent to estimate your sleep.

Is PeakState a medical app?

No. PeakState provides insights for reference only. It is not a medical device and does not diagnose, treat or prevent any condition. Please consult a healthcare professional for medical concerns.
