It's a good app but can be better I want the developer to fix the following please: 1-when you work with it sometimes it becomes laggy and you need to force stop and restart the app 2-when you type in it in Persian the symbols like "?, (,), etc" doesn't align correctly 3 - if you add some native calendars like Persian calendar to it it will become more useful (and also an option to set it as main calendar not like Google alternative calendars that show Gregorian months not Persian months ex.)
