Kajo: Cortisol & Rhythm Coach

Exhausted all day but wide awake at night? Kajo acts as a translator for your body. Turn your health data into a daily plan to master your cortisol and find your rhythm.

Get in Sync with Your Body Ever feel exhausted all day but wide awake at night? That’s not just stress—that’s your body’s rhythm being out of sync. Your cortisol is spiking when it should be dropping. Kajo helps you find your rhythm again.

More Than Just Data Most trackers just give you raw numbers. Kajo acts as a translator for your body. It turns your sleep, heart rate, and activity data into clear insights about your nervous system state.

Your Daily Coach Instead of just showing graphs, Kajo gives you a daily plan. It coaches you on the small, smart choices that actually matter to shift your body from "survival mode" back to balance: • Daily Rhythm Score: See your capacity for the day based on Sleep, HRV, and Resting Heart Rate. • Smart Timing: Know exactly when to stop caffeine, when to eat your last meal, and when to dim the lights to align with your biology. • Nervous System Balance: Understand if you are "Strained," "Balanced," or "Optimal" and get advice. • Actionable Habits: Track science-backed tools like Morning Sunlight, Physiological Sighs, and Cold Exposure to boost your score. • Instant Regulation: Use built-in soundscapes (40Hz/10Hz/4Hz), visual breathing, and timers to focus, rest, or recharge on demand. • Build Consistency: Visualize your streaks and see how small daily choices compound into better health.

Privacy & Security Kajo is built with privacy at its core. We do not store your health data on our servers. Kajo reads directly from Apple Health and any backups remain exclusively within your personal iCloud account, under your control.
