Unfortunately this is a lie. After making the purchase, I was not able to put a start date on any of my cards so I reached out to support and found out that Any.do doesn't support this feature. Very disappointed that the one feature I purchased for isn't there.

As mentioned previously, events will always have a start and an end date. It sounds like you're looking to add these to tasks, which was never an option. Our response specifically stated this is available for event-type items only.
