mobile interface suggestion
I can't tell you how many times I have failed a response on the mobile interface because of "fat fingers". I prematurely, accidentally touch the CHECK or the DONE buttons and poof, I've lost a heart. I wish there was a way the Owl would protect me from this mal-maneuver. For example, if the word count between the translated and untranslated sentences are not close, the Owl could present a dialog that says "Are you ready to submit your response?".
The pop up keyboard is also a real issue, you should have it up all the time and/or move the submit button above the top or to the side ( so it only shows in an area of the screen that is never used for typing/audio ). Being in between has cause me to hit it accidentally in the lag between pop-down and pop-up, especially when attempting to edit using the magnifying glass.
