Activity Diary

Activity Diary is an Android application for recording what you do during the day and for keeping track of activities that repeat. Entries are logged as they happen or afterwards, building up a history that can be consulted later; the same list of recurring activities also serves as the basis for planning ahead.

The emphasis is on activities that come round again — chores, exercise, study sessions, habits — rather than on one-off appointments, so the record accumulates into a picture of how time is actually spent over weeks and months. Because the log is kept on the device, the application is a personal diary rather than a shared calendar.

It is available for Android only and is released under GPL-3.0-or-later. Users who need synchronisation across several devices, or a shared team schedule, should check whether the application covers that before adopting it.
