Why use WhenDidI?

There are plenty of apps to keep track of finances, exercise amounts or calories eaten. Some are very basic, others require you to add lots of information to fully use the app.

But what if you do not want to use multiple apps, but just need to keep note of a few important events in one place. For example just the cost of your lunches, along with when you last had a hair cut, and how has your weight been changing over the year.

With WhenDidI, you can store the times of different event types, along with a cost value, or a measurement of your choice. Have all the informaton, easily accessiable from one place.

Events in Spreadsheets

Turn you events list in a comma delimited csv file, and share as an email attachment. CSV files can be viewed in spreadsheets.


Register event notification alerts to appear at particular times of the week, month or even a number of days after the last event.

Quick links

Favourite a particular chart view, or an add event entry. Place these favourites on the home page as widgets.
