I'm one of the few users who is still a heavy user of DoIt and everything is still working great! I use it everyday to sort out my life and would be lost without it.
I'm a pro user and it has been activating successfully every year. I've never lost any data - and the calendar sync works great!
There's honestly not much out there which works as brilliantly as DoIt.
I just want to encourage the developers to keep the product going and feel proud, and continue working on it.
An amazing product
