The simplicity is nice, but sometimes I want something with more detail. I use it in conjunction with another app. If I don't have a lot of time to enter info, it's great for that. I like that you can change the background to dark which isn't so jarring if you are using just before bed and are trying to avoid being stimulated by technology. I do wish, though, that you could change the setup of a Habit entered between a simple click or entering more detail. Right now you have to create a new Habit if you want to change, but then that changes your stats.
