Make date format configurable or adjust it to current locale
Localization shouldn't be a topic for this app I think, but at least the date formats should be configurable or you shoud set it to the current locale format.
A date like 9/10/2015 is always causing trouble: is it american format and means mm/dd/yyyy or is it BE and is dd/mm/yyyy?
I'd suggest to use either an ISO date format like YYYY-MM-DD
or display it in the iPhone's current Locale (DE: 9.10.2015).
