This was a great app, a year or more, ago. The simplicity of adding and checking off tasks, without clutter of a bunch of fancy features, was it's strength. Basically, it was as simple as making a list on a piece of paper, with the added bonus of having reminders. Now, however, it requires more steps to add to-dos, and is becoming more of a complicated app, loosing the original appeal. As of some time ago, notifications also stopped working, which mean I will leave, after some 5+ years of use.
