Durations is a simple app for logging events as they occur, and seeing 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 contact lenses etc.
Alternatively, 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 containing tags and timestamps. This spreadsheet can be imported into zenobase.com for further analysis, or used elsewhere.
This app is available on Google Play and in the App Store.
The complete source code for this app is available here.
