Luna: Sleep Tracker & Sounds

Luna is a sleep companion: it sums up your night, explains in plain words what may have shaped your sleep, and gives you one clear step for tonight. No account, no ads, no internet — your data stays on your phone.

★ Sleep tracking and a nightly score
Luna reads your sleep from Health Connect: sleep duration, regularity, awakenings and — when your watch or ring records them — sleep stages (deep, light, REM), resting heart rate, heart rate variability and respiratory rate. Every morning your night comes as one score and a clear summary, with 7-, 30- and 90-day trends for your sleep pattern.

★ One step for tonight
A target bedtime that takes your sleep debt into account, and one suggestion for the evening: a breathing exercise, a Wind Down routine or a calming sound. No long lists — just what helps tonight.

★ Sleep sounds and white noise
Rain sounds, forest, stream, fireplace, ocean waves, night sounds and pink noise. Mix up to three sounds and set a sleep timer; they keep playing with the screen off.

★ Sleep stories
Calm bedtime stories narrated in English and Turkish, each with its own ambient sound underneath.

★ Breathing exercises and Wind Down
4-4, 4-7-8, box breathing and free-rhythm breathing, plus a short evening routine to get ready for sleep.

★ Sleep Mode and alarm
The wake-up alarm you set in Sleep Mode rings on the lock screen and in silent mode. There is a nap timer too.

★ Progress
A 5-second check-in: coffee, alcohol, a late meal, stress, exercise, a screen in bed, a nap. Over weeks Luna shows which habits tend to come with your nights — never from a single night. One priority to try each week.

★ Privacy
Luna has no account and no server, and it doesn't connect to the internet. Your health data is only read and stays on your phone; it is sent nowhere. No ads, no analytics, no tracking.

Basic is free: the night summary, Tonight's suggestion, the alarm and Sleep Mode, the check-in, 4-4 breathing and the 7-day trend. Premium (a monthly or yearly subscription) adds all sounds and stories, Wind Down, the other breathing exercises, the nap timer, 30- and 90-day trends and the weekly priority. New subscribers can try Premium free for 7 days; unless cancelled before the trial ends, the plan's price is charged. The subscription renews automatically until you cancel it in Google Play → Subscriptions.
