Dromu

Dromu is a nighttime touch game that turns your screen pitch black and guides you toward sleep through nothing but the feel of your fingertip. Close your eyes and slowly trace your finger across the screen. A gentle vibration answers back, following your own rhythm. No bright light, nothing to look at — just the sensation under your finger, until, almost without noticing, you've drifted off. That's the nightly ritual Dromu is built around. CHOOSE TONIGHT'S VIBRATION Breeze, Gentle Waves, or Cat's Purr — pick whichever fits a sleepless night. ONE TAP TO START Dromu remembers what you picked last time, so you can start the moment you're in bed. TRACK YOUR TIME TO SLEEP The next morning, a few quick questions record how you felt, whether you put your phone down, and roughly how long it took you to fall asleep. Your records stay on your device. If you agree, and only on devices set to Japan, some usage data is sent to help improve the app — see the Privacy Policy for details. YOUR STREAK See how many nights in a row you've kept it up, at your own pace. — Dromu is a game app, not a medical device. It is not designed to diagnose or treat insomnia or any other condition, and makes no medical claims. If you need medical advice, please consult a qualified healthcare professional. SUPPORTED DEVICES To feel the vibrations you need an iPhone 12 or later (Taptic Engine). On iPad and other devices without haptics, the pitch-black screen and sleep log still work — just without vibration.
