Those two statements right there are holding you back. 1) You should ALWAYS be considering features that users want if you're trying to become profitable. If this was a charity app then sure, do whatever you want. BUT this is not, according to your blog. Put the user's needs before your own. 2) You may have a decent feel of what it takes to learn a language but I bet you a day of true market research would open your eyes to features/enhancements that you would have never even considered.
Anyway, that's my 2 cents. I think the app is really cool!
