## What is SleepLock?

SleepDown is a bedtime alarm for people who keep scrolling after they meant to stop.

SleepDown doesn’t just remind you. It asks you to take action: open the app and put your iPhone face down.

Set your bedtime and choose the nights you want it to repeat. When bedtime arrives, SleepDown starts a prominent reminder. To complete your bedtime task, open SleepDown and leave your iPhone screen-down for a few continuous seconds.

Silencing the system alarm does not mark bedtime as complete. SleepDown keeps the task unfinished until you actually put the phone down.

FEATURES

• Create recurring bedtime schedules
• Get a wind-down countdown before bedtime
• See bedtime status on the Lock Screen and Dynamic Island
• Put your iPhone face down to complete bedtime
• Optionally require a power connection
• Choose how long the phone must remain face down
• Review when you actually put your phone down
• Choose from three included alarm sounds

PRIVATE BY DESIGN

SleepDown has no account, advertising, analytics, tracking, or cloud verification. It does not use your camera, microphone, location, contacts, or photos. Your schedules, settings, and completion history stay on your device.

SleepDown does not measure sleep duration, sleep quality, or sleep stages. It focuses on one moment: helping you stop using your phone and call it a night.
