A new task list app called Coming Up sounded promising. But fails in execution. While many people appear to have trouble getting it up and running, that's not my problem, on my Epix Gen 2. But Google Tasks events get date wrong. For example, if entered in Google as Feb. 20, it appears on the watch as Feb. 19, always one day early (which I suppose is better than one day late).
A second problem is that the event's time does not appear on the watch, using either Google Tasks or Microsoft To Do.
So the app is great as long as you don't care about the date or time of your events.
