We have a company calendar already in Google Calendar, wasn't clear how to get this app integrated for employees to add direct to the calendar via the app. Still not sure, I can get it to add to my own calendar fine, but I wanted it to add to the company calendar, that step is unclear. Downloaded iPhone version, but was sadly disappointed I couldn't find a way to change a holiday once booked via the iPhone, so that makes the app rather useless at present. So I've hit a brick wall with this now, which is shame since most other things seem to work nicely. A future suggestion would also be nice not to show how many days left to book for an employee, just a notice once there are no more days left to book.
