Koru: Breathing Exercises
Stress & Anxiety Relief, Sleep
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Tell Koru how you want to feel: calm, focused, energized or ready for sleep. Get a guided breathing practice matched to that state, from 1 to 15 minutes.
How do you want to feel right now? Calm, focused, energized, ready for sleep? Pick a state and Koru gives you a guided breathing practice to get there, in 1 to 15 minutes.
ONE-MINUTE RESET WHEN STRESS HITS
Four SOS practices, one minute each: Stress Reset, Fast Relax, Quick Focus and Energy Boost. They work offline, so they are there on a plane, before a hard conversation or at 3 a.m.
LEARNS WHAT WORKS FOR YOU
Check in before and after each session. Koru shows how your state changed and, with Apple Watch, how your heart rate responded. Over time you see which practices work for your body.
YOUR AI BREATHING COACH
Tell the coach how you feel in your own words. It suggests three practices matched to your state and the time you have.
CALM IS TWO TAPS AWAY
Start a practice with Siri, Shortcuts, Back Tap or a Home Screen quick action. Save a favorite for offline use.
WIND DOWN FOR EASIER SLEEP
Slow, guided breathing to quiet a busy mind before bed.
30+ GUIDED PRACTICES
Box breathing, 4-7-8, resonant breathing, Nadi Shodhana, ocean breathing and more, grouped by goal: Calm, Sleep, Focus, Energy, Recovery.
MULTI-DAY COURSES
Build the habit with day-by-day programs, from a 7-day introduction to a 30-day breath hold course.
MAKE EVERY SESSION YOURS
Voice guidance, background music, metronome and vibration, each adjustable.

Koru now starts with one question: how do you want to feel right now?
• Pick a state: Calm, Reset, Focus, Energy, Restore or Sleep. Koru matches a breathing practice to it.
• Check in before and after each session to see what worked for you.
• Heart rate with Apple Watch: see how your body responded.
• AI breathing coach: describe how you feel and get three matched practices.
• Siri, Shortcuts and Back Tap: start an SOS practice without opening the app.
• Koru on Apple Watch: SOS practices, favorites and the exercise of the day.
