AI Energy Assistant

A 24/7 companion powered by Claude AI. It knows your data, remembers your patterns, and gives advice that’s personal — not generic.

Deep Sleep Analysis

Understand how Deep, REM and light sleep shape your recovery — and get specific suggestions to sleep better tonight.

87 Intervention Tools

Breathing, focus timers, mindfulness, digital detox and more — across four dimensions: physical, emotional, mental and willpower.

Screen Time Management

See where your attention really goes. Spot addictive patterns, set healthy limits, and reclaim your focus.

Work Density Analysis

Reads your calendar to flag overwork risk and protect recovery time.

Environment Monitoring

Weather, air quality and noise, scored for their impact on your energy.

From data to decisions in three steps.

  1. 01

    Connect

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

  2. 02

    Understand

    PeakState builds your personal energy model and forecasts your next 24 hours.

  3. 03

    Act

    Get timely, specific guidance — when to focus, when to rest, and which of the 87 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 to help prevent burnout before it builds.

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.
