I downloaded it from the Amazon App store, could try contacting Amazon but I'm sure they would just refer me back to the developer of the app itself.
I want to use Evernote (compared to similar apps) as it supports offline usage, as I work where an internet connection can be sparse, so want to have something which still allows me to use it and then resynch once the tablet has gained an internet connection again.
Appreciate the response and guidance though.
