When Did I?

When Did I? helps you remember when you last did everyday tasks, routines, and personal activities.

Instead of trying to remember dates yourself, you can record an activity once and quickly check how many days have passed since the last time. It is useful for things that do not happen every day but still need to be tracked from time to time.

Main features:

* Record activities with dates
* Check elapsed days at a glance
* View records on a monthly calendar
* Set repeat intervals for recurring activities
* See upcoming or overdue schedules
* Add reminders for activities you do not want to forget
* Review activity details and history
* Manage records locally on your device

When Did I? is designed for simple personal tracking, such as maintenance tasks, health routines, household chores, personal habits, replacement cycles, or anything you often wonder, “When did I do that?”

The app does not require account registration. Your records are stored locally on your device.
