This is by far the best to do list app I've come by. It has rich features and a great interface, even in the free version. It knows the difference between a task, and a habit. My main issue here with the app, is premium pricing. Why exactly do I have to pay a monthly fee for features that can be used offline? Normally, a monthly subscription is to support features that need to be consistently paid for. From what I can see, there's only one. If a one time payment option is added, I'll buy it.
