Dementia Diary started life with no configurable options at all, today there are are large number of options mostly based on the feedback of it's users (Thank You).
This section captures some of the most asked questions about the app and provides some simple howto's.
In order to access the various menu options just long press (1 second) the top left corner of the screen (the yellow area in the image on the left).
You may have screen lock enabled, in which case just tap the same area five times and try again. (There should be a notification in the bottom centre of the screen that screen lock was turned off.)
You can only use photos in Digital mode i.e. without the analog clock showing - not as seen in the image on the right. (Sorry, maybe in a future version)
