My wife is searching a diary app for OS X. Ideally it should be like this on Windows 10 https://www.microsoft.com/en-us/stor...l/9wzdncrdmr7x But that is Windows only. I think most important is that it should have an old style and be able to add pictures. Regards Roland
Try DayOne. It's one of best in App Store. Can sync with iPhone/iPad through iCloud, dropbox etc and support markdown format.
Day One is absolutely the best I've come across. It has an iOS client as well. Doesn't have an "old style" though, for which I am grateful.
