## What is Peak 90?

Add Years to Your Life. Literally.

Peak is the only habit tracking app that quantifies the exact impact of your daily habits on your lifespan. Unlike generic habit trackers that show streaks and completion rates, Peak shows you how many potential days you're actually adding back to your life expectancy—based on real science, not guesswork.

WHAT MAKES PEAK DIFFERENT

Life Days Regained — See exactly how many days you're adding to your life with every habit completion. Complete a cardio workout? See "+0.65 days regained" immediately. Track your cumulative life days and watch your potential life expectancy grow in real-time.

Backed by knowledge — Every habit's life impact is calculated from proven impact: Tier 1 habits (cardio, sleep, nutrition) directly extend life expectancy, while Tier 2 and Tier 3 habits improve quality of life and build identity.

Human Performance Index (HPI) — Track your performance across 5 domains: Longevity, Energy, Mental Resilience, Social Connection, and Self-Control. Get a composite score (0-100) that shows your overall health and performance.

• Burnout Risk Monitoring — Prevent over-optimization with real-time burnout risk alerts. The system tracks recovery habits and warns when you're pushing too hard, helping you balance performance with recovery.

• 90-Day Life Reset Journey — Structured transformation through 5 stages: Resetting → Stabilising → Rebuilding → Transforming → Compounding. Each stage has specific focus areas, recommendations, and milestone celebrations.

• Integrated Recovery Tools — Built-in Zen Breathing exercises (4-7-8 pattern, Box Breathing) and breath hold training. Meditation and breathwork tracking prevent burnout while optimizing performance.

THE SCIENCE BEHIND PEAK

Peak's calculations are based on peer-reviewed research on mortality risk reduction. Each habit's life impact is derived from population-level studies showing how specific behaviors affect life expectancy. We apply conservative scaling factors to ensure realistic daily gains.
