About

Luna: Sleep & Relax is a sleep companion for iPhone. Each morning it sums up your night from Apple Health, explains in plain words what may have shaped it, and gives you one clear step for tonight. Measure, understand, take the one right step for tonight.

Night summary and sleep score. Duration, regularity and continuity from the sleep in Apple Health — plus sleep stages and night heart data when you sleep with an Apple Watch. When some data is missing, the score is worked out from what is there instead of being marked down, and Luna always shows where the data came from and when it last synced.

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.

Improve. A 5-second check-in: coffee, alcohol, a late meal, stress, exercise, a screen in bed, a nap. Luna compares only nights you checked in on that have sleep data, and draws no conclusions from a single night or too few. A weekly priority gives you one concrete thing to try each week.

Sounds, stories and breathing. Mix up to three ambient sounds — rain, forest, stream, fireplace, ocean, night sounds and pink noise — and set a timer. Listen to sleep stories narrated in Turkish and English, each with its own ambient sound underneath. Try 4-4, 4-7-8, box or free-rhythm breathing, or a Wind Down routine before bed.

Sleep Mode and alarm. Start Sleep Mode with your wake-up alarm. On iOS 26 and later the alarm rings on the lock screen, in silent mode and with a Focus on; on earlier iOS versions it rings while Luna stays open in the background.

Your data stays on your phone. Luna has no server and sends your data nowhere. There is no account, no ads, no analytics and no tracking: Apple Health data is only read, and everything Luna keeps stays on your iPhone.

Free for 7 days, then Basic or Premium. Every new user gets 7 days of full Premium automatically, with no payment. Afterwards Luna stays free in Basic mode — the night summary, Tonight’s suggestion, the alarm and Sleep Mode, the check-in, 4-4 breathing and the 7-day trend. Premium adds all sounds and stories, Wind Down, the other breathing exercises, the nap timer, 30- and 90-day trends, check-in comparisons and the weekly priority, as a monthly or yearly subscription through the App Store.
