It appears that it is possible to set the time of an alarm only by selecting from a limited list of predefined values. That is a serious limitation. For example, I would like to be reminded of a task set for the middle of tomorrow afternoon at the end of today. That would require something like 18 hours before. As far as I understand, there is no way to do it. That is really surprising. Other similar applications, like Google Calendar, allow to type in any value you want. It is even more surprising in view of the fact that Toodledo gives a lot of latitude in inputs into other fields and correctly converts the free input into a standard, expected value.
