## What is Sleke?

Going to bed now? Sleke is a sleep cycle calculator and smart alarm that tells you when to wake up.

Sleep moves in cycles of about 90 minutes. Waking at the end of a cycle, in light sleep, feels very different from being pulled out of deep sleep. Sleke times your alarm to those moments, so you wake up clearer and less groggy.

HOW IT WORKS
• Open Sleke at bedtime. It adds the time you usually take to fall asleep and shows wake-up times for 4, 5 or 6 full cycles.
• Pick a time, with the best fit marked, and tap Start sleeping.
• Lock your phone and sleep. A real iOS alarm rings at the end of your last cycle, even when Sleke is closed. Snooze, or slide to stop.

NEW IN SLEKE 2.0
• Snore clips. Sleke listens on your iPhone while you sleep and saves short clips when it hears snoring. Play them back in the morning and see when each one happened on the night's timeline.
• Your week at a glance. A chart of every night: when you went to bed, when you woke, and whether you woke on time, stopped early or slept past the alarm.
• A new look. A deep night-indigo design and a new app icon.

SEE HOW EVERY NIGHT WENT
• Average time asleep and how many nights you woke on time
• Each night drawn as its sleep cycles, with snoring marked
• A short summary of how the night went

POWER NAPS
Start a 20 to 60 minute power nap with the nap timer, or just say "Start nap in Sleke".

SET IT TO HOW YOU SLEEP
• How long you take to fall asleep
• How long your cycles last and how many you aim for
• Alarm sound and snooze length

HANDS-FREE WITH SIRI
Say "Start sleep session in Sleke", "Start nap in Sleke" or "Cancel sleep session in Sleke", or add them to Shortcuts.

SLEKE PREMIUM
Starting sleep sessions and naps needs Sleke Premium. Try it free for 1 week, then $0.99 a month. Your subscription includes every feature, from snore clips to iCloud sync across your Apple devices.
