I prefer #remind for my work shedule - it is very convenient for creating any timetables. You can keep your shedule in plaintext, can create sofisticated events (odd/even weeks, for example). And it's much more simple to do when put every event into #GoogleCalendar. But remind badly connects with #android phone calendar (#etar in my case).
Today just connect #fdroid powered toolchain:
Works like charm.
