It might sound a bit fussy, but being able to set times in 24-hour format is an absolute must if the Agenda app is to be of any use to me at all. So far, I haven't found a way of being able to do this. If it can't be done, I'll have to use a different app. I work in an industry that uses 24-hour times in all its operations, and it's pretty important for me to be able to record them.
Any other good diary/agenda apps that support it, if the Planet one doesn't?
