Because I launched it as a free app... I didn't have any confidence in it and at that moment, there was no way for me to accept payments internationally.
I recently revamped the app, added features like real-time collaboration, chrome-app integration etc., and put that under a subscription. But have no time to market or spread the word around. Moreover, I'm not sure how to get free users to convert over to paid so, that's why exactly why I think this site is an apt example for this topic.. haha!
Just an idea.. Try the wikipedia model maybe and ask for some donations if you've been using the app. I did this with an old product and it was helpful.
