Honestly the premium version is just not worth it, what's the point of having advanced calendar views and event setup and calendar import if, in every case, you can't see future recurring events? (The next event in the list of recurring appears only if you have ticked off the previous instance) In order to use a calendar efficiently for planning you ought to see what events are next, this hindrance has been made present by the users as far as 2015 (as I'm seeing online) and nothing has been done, that not only shows poor hindsight (what's a calendar without planning) but also a strikingly deaf customer service. The app is probably just as good as its free version, the pomodoro timer is ok, but the extra features are just not worth the expense for the premium version.
