Thank you for making this app! I am really happy to see something like Crinkles available for Android, and am tickled to find all the brands I'm currently using.

One suggestion I'd like to make that could make this easier to use for me:

Could you add a bigger "add change" button / icon near the bottom-right of the screen?

I had a bit of trouble finding it at first in the "History" view, and the icon is really small and on the upper right corner (which for somebody that uses my phone usually single-handed is a bit annoying).

I think adding a " " icon on the bottom right, like in the Catalog view, would be perfect. (only showing it when you e.g. aren't already wearing one)
