Privacy-first Android app to track outdoor time. Do you spend too much time looking at a screen? TouchGrass is the simple way to track your time in nature. Whether you want to increase your sunlight exposure or just need a nudge to go for a walk, TouchGrass helps you find your balance. Most trackers want your data. TouchGrass only wants you to enjoy the fresh air. The app learns your schedule and sends a nudge when it’s the best time to head out—without ever sending your location to the cloud.
