Lakota Keyboard on iOS devices?

Háu mitákuyepi!
I remember reading somewhere on the forum that someone had been working on an iPhone/iPad app for the Lakota keyboard. I found this one online: http://www.148apps.com/app/641748700
It doesn't work in the USA, however, so I don't know if this is the same one someone had been discussing.
How is everyone writing in Lakota on their phones? I've been using the Anki flashcard app on my phone, but I'm unable to add to it until I get back to my main computer.
Any help is appreciated! Wóphila!
