I think you should give people an option to get the full version of the application in return for viral actions.
Some people prefer not to pay but would rave about your app to 10 people (e.g. like dropbox, where both sides get some space for free in case of a referral). You could give 2 months free for every person that somebody gets to join (to both the referrer and the new user).
I think otherwise you may be crippling your own growth. Also, I'm sure you can find other premium needs that people would pay for and that don't detract from the experience for the non-paying user.
Lemme know if you want to chat. I like the app a lot and would love to see it get into as many hands as possible :)
