AnkiDroid is an open source project developed by a third party, AnkiMobile is developed by the Anki developer, who is perpetually trying to find ways to fund the development of Anki.
Seems like a very good scheme IMO. With all the hype about Anki and how good it is lots of people will want to try it out. After finding out that it actually is good they might want to use it more frequent i.e. on the iPhone. And then they'll most likely buy it despite the price.
I know I will, anyway. And since Anki is open source and free I feel that the price will keep him motivated to improve on all things.
It's still very worth it. It's the one app I'll never uninstall.
Agreed. Years ago, it took me a few weeks to see the utility of Anki, then I bought the iOS app to support the developer's efforts. I use Anki more frequently on Android however.
If you are averse to the price, sometimes there are sales you can check: http://appshopper.com/education/ankisrs but in the goodwill of giving back when you benefit, pay what you can.
