DaySlice
Make this turn yours.
See a day as one turn of Earth. A gentle visualization of time, with daily check-ins, widgets, and the weather.
A water clock, a sundial, a 100-square map of the year. DaySlice gives time a visible shape, so you can notice where you are in your day and year. Opening the app checks in automatically, and widgets keep today close.

A few useful answers
Do I have to share my location?
No. Tokyo is the default weather location. Permission is requested only if you choose local weather, and location is never stored.
How do daily check-ins work?
Your first launch each day automatically checks you in. Records stay on your device.
What does the Earth rotation count mean?
It expresses the civil-day count since January 1, year 1 as Earth rotations. It is a calendar-based visualization, not a measurement of Earth’s physical rotation.
