Doesn't work – ShareCal - Easy Calendar Event Sharing via Email, iMessage and AirDrop Review

I saw this up on Google search when I was searching for a calendar to share. It showed that it had a lot of ratings and a lot of users downloaded it. However it doesn't work and the app seems to be missed placed with something else. It doesn't sync with my calendar as well.
