I recently signed up with Acorn.tv and was trying to download on my iphone... I called in-they knew exactly how to walk me through downloading the app and even sent a follow up email with additional instructions because I said I wanted to watch on my Kindle Fire also. The programs have been entertaining so far and I am hook'd on the ease of use. Thank you Acorn for providing a worthwhile service at an affordable price that is easy to use for all.
