Not worth it
Doesn’t allow you to edit mistakes . Good idea for an app but due to the above mentioned factor it’s not useful as we humans always make mistakes. If you do one you have to manually charge the year altogether not the dates. You cannot scroll dates on the left of calendar. Thus if you’re in one place on the 20th of a given month you are not allowed to include that you are in the next place on te 21st. Don’t buy it. Will drive you nuts.
