Currently comparing 2Do and Todoist. 2Do feels gratuitously overpowered for a todo app, to the point it feels unnecessary. Todoist offers a much simpler feel to a simple todo list.
And then there is the matter of syncing. Todoist does it automagically, while 2Do requires you to setup your own solution. Not completly outside the realm of possibility, but still feels like a hassle. But then again, I never use Todoist on my computer, so syncing isn’t that much of a factor.
However, Premium (If I ever buy it) is a one time purchase on 2do, but a 45 dollar a year subscription on Todoist. Trialing both right now, but if I ever want an advanced todo manager, I will likely go for 2Do.
