I wonder if the official smartphone app uses the same API as the one exposed and documented for third-party apps. It's my understanding that it does not because the unofficial app I use (reddit is fun) lacks some features, so just borrowing the official app's key and putting it in RiF is out, but surely it would be possible to adapt a FOSS app like Slide to quack like the Blessed Official App and let the arms race begin, no?
