I dont know why another reviewer said you cant delete or mark as done. Just swipe to the right. Its both a feature and a draw back that the interface is quite minimalist - some functions are not obvious. Thats part of the draw though. You want get the noise of an interface out of the way so you can focus on what needs to get done. I dont put a lot of things on this app. I use it to keep me focused on things that dont make a lot of "noise" but are important to work on and get done or to track things that are easy to overlook. Ive found it helpful for getting things done, which makes it worth the price.
