Responsive UI

[Alexciao]

Describe the feature

I think that being able to use the app from mobile would be cool. I don't think that it's necessary to implement ALL of the app's views in a responsive manner, but just enough to add (& possibly view) transactions on the go.

Why is this feature important?

I think that adding transactions on the go is important because when I get home I often forget to add them, resulting in an outdated finance tracker.
