Very good

Info is always good and this app has it. Here is what is wrong with this app: 1.) The user interface is very un intuitive, this app assumes you can figure it out right away, and has things placed, as though you have already gotten a walk through. 2.) The app does not communicate about it’s mode of monitization, until you are already knees deep in frustrating menu’s trying to figure out how to compose or even study with it. Overall pretty sus, if you ask me.
