While the app is good for some basic debt and payment calculations, it has some issues. Warnings to let you know required data in a field is missing show up out of the viewing area. Since you cant continue until the error is fixed, you have to figure out what is wrong or missing yourself before you can continue. This seems to be the case for emailing the data too, so its not possible to use that function at all.
