Inefficient user experience

Although the summary tab generates a visually pleasant graph, everything else is confusing in the app.
Editing entries is anything but straightforward (just as deleting accidental entries - which are quite easy to make).
The same goes for switching the summary graph from "daily" to "last month" or "total" - I havent actually figured out how to do that... Viewing a long term history is pretty much the point of this, no?
All these makes the entire app cumbersome and difficult to use.
I dont understand the consensus of the other reviews really.
