I'm looking for an Android calendar app with a very specific feature: I want to be able to add events with no known end time. Don't get me wrong, I'm not talking about "all-day" events which have no start time either; I'm specifically looking to add events that have a start time, but don't have end time.
The very idea of all events having known end times is very confusing to me. If I'm going to a meeting, how do I know if it will last 30 min, 45, or one hour? If I'm going to the movies, how do I know how long will I stay having drinks afterwards? It's very surprising to me that so many apps force people to add some end times which are probably nonsense in 90% of the cases.
