24 Hour Solar Clock · iOS · Free with Sol Pro
The 24 hour clock divides the day into solar and lunar periods — anchored to solar noon, sunrise and sunset instead of a modern clock.
Sol Clock brings this ancient way of experiencing time to your iPhone. It's the same solar-anchored timekeeping system as Ave Maria Clock, built for anyone who wants to reconnect with the natural rhythm of the day.
