Good job, @brianoflondon, but I found a bug. The app does not show the value after the decimal point. If I want to do a transfer of 10.5 HBD it does a transfer of 10 HBD.
EDIT: I know where the problem is. There should be a dot instead of a comma. Unfortunately on my iphone I don't have the option to type a dot.
No dot. Only coma. So I have to write as a memo 10.5 and then copy as a amount... A bit annoying.
