Echo

Echo is a lightweight journal that helps you discover which daily habits are actually improving (or hurting) your HRV and recovery.

Track your cold plunges, sleep, workouts, alcohol, stress, and more — Echo connects your daily habits with your wearable data (like Oura, Apple Watch, or Whoop) to uncover what actually improves your HRV, recovery, and well-being. Join the private beta to log, reflect, and find patterns in your health data that help you optimize your day — without spreadsheets, guesswork, or endless advice that doesn’t work for you.
