The MVP is pretty simple, the app has three views. The first one, a welcome views with some punctual info about how your bussiness/personal accounts is/are going. The second one, a monthly view with the detailed information about each income/expense. The last one, a view with some charts which displays the information in a useful way.
Nothing fancy, but my idea is to have this app as a "base" and start growing with new features on the go.
What I like about my app is that it's really simple, you don't need to configure nothing and you have a useful app in a few minutes.
