* Using other apps does not interrupt the timer, no need to keep the widget open (BUT: there will be no buzz when the time is up, for that the widget has to be loaded)
* Target time is saved to a file and timer picks up again when widget is loaded again.
## Settings
There are no settings section in the settings app, timer can be set using an app.
* Timer on: Starts the timer and displays the widget when set to 'On'. You have to leave the app to load the widget which starts the timer. The widget is always there, but only visible when timer is on.
