One or two minor hiccups when inserting advance appointments which resulted in a difficulty with getting the diary back to 'todays' date. I had to turn the phone on and off in order to correct this. Also had problems with the app widget failing to download after the phone has been turned on. Other than those issues the diary has been great. I would love to have more options to customise the appearance of the app, eg background or page colour options only work when you insert an appointment.
