## What is SemiSleep?

SemiSleep is a quiet bedtime meter for people who want to make the most of every day.

There are plenty of alarm apps and sleep trackers. SemiSleep looks at the other side of the day: the time you have left before bed.

Set your bedtime, and SemiSleep shows how much waking time remains through calm, visual meters on your iPhone, iPad, Home Screen widgets, Lock Screen widgets, and Apple Watch.

You may be surprised how short a day feels when the time you can stay awake is made visible.

Main Features:
- Home Screen and Lock Screen widgets
- Bedtime and wake-up time settings
- Visual meters that make remaining time easy to feel at a glance
- Apple Watch support
