Klar Health

Listen to your body. KLAR Health redefines stress, sleep, and HRV tracking with advanced biometric insights and an empathetic, anxiety-shielding Zen Mode.

Klar reads the signals your body already sends to Apple Health and turns them into one calm, clear picture of how you're doing today.

No manual logging. No noise. Just the numbers that matter.

Every morning, Klar blends your heart rate variability, resting heart rate and sleep into a single recovery score from 0 to 100, so you know whether to push hard or take it easy, before your day starts.

Klar's Wellness Shield watches for the subtle multi-day shifts in your resting heart rate that often show up before you feel run down, a gentle, non-diagnostic nudge to rest.

EVERYTHING IN ONE PLACE

• Fitness: VO2max trend and an approximate fitness age • Sleep: quality and consistency over time • Calories: a smart daily energy balance built from your steps and workouts • Weight: a smoothed trend plus a gentle forecast • Cycle: phase-aware insights for those who want them (Menstrual Cycle) • Habit journal: tag your day and let Klar surface what's actually connected

A quiet, spatial glass design. Rare, thoughtful notifications. And Zen mode when you just need to breathe.

Your health data is used only to calculate your scores on your device and syncs privately through your own iCloud. It is never sent to Klar's servers.
