Lunar Reminder

Tradition. In your pocket.

A lunar calendar and reminders for the dates that matter, brought into an everyday mobile experience.

01 / The problem

Why it exists.

For families who observe the first and fifteenth of each lunar month, the dates shift against the everyday calendar and are easy to miss.

One calendar shows both systems at once. Each day carries its lunar date under the Gregorian one, and the days that matter are marked ahead of time.
