3years and going!!
My family has loved this App! We have it on all of our devices and use it to keep track of everything we are doing in our google calendars. We never double book anything since the app syncs the moment we add anything. I also love being able to see a "preview" of what we put on specific dates while its in the 31day view. Overall Ive never had one issue with this app or google colander, and hope I never do.
