Awful UX/UI - I don't like how you have to use a rigid syntax to set recurrence for tasks. I like old fashioned controls, but Todoist is just trying to be different for no reason. Was on Premium for several months and gave it a fair shot - needless to say, I cancelled my subscription and switched to TickTick instead. I don't normally downvote apps, but this just didn't do it for me, and I spent money on it. I should have ignored the hype, so the fault is mine.
