Check out Any.do. It's a little too simple for me, I personally use ticktick which has geolocation on tasks and a lot of other features (including my preferred style of UI, the Things style), but any.do has a fantastic simple UI and has a "Moment" feature that pops up every morning where you get a list of your currently waiting tasks and get to determine whether or not you decide to complete them that day or not. There's also Clear which is a very simple daily task manager.

I'm personally not a fan of the simple UIs and greatly prefer the Things style (menubar on left with projects/lists/etc).
