Zenobase Durations play online

Log events as they occur, and see how much time has passed since the last occurrence.

This can be useful for keeping an eye on things that don't have fixed expiration dates, like how long it has been since you last replaced your toothbrush... Or you might want to keep track of how long you can go between events you are trying to avoid.

Data is stored locally, and can be exported to a spreadsheet.

Translated to English, French and German.

Supports both light and dark themes.
