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.

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.

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.
