I used androidlicenser to implement an upgrade function that allows unlocking additional features. Users can pay though Google Checkout or Paypal and you keep almost 100% of the money (minus ~2% transaction fee). It's also not limited to the 29 country Android market is currently limited to. For the user it's convenient because he/she doesn't have to download another app, doesn't lose the data already entered/accumulated in the free version and can pay by other means than Google checkout.
So basically I have 2 1/2 half versions: - Free app - Free app unlocked = identical functionality as the paid app - Paid app I'm going to release the unlock function next week and if anyone is interested I can share my experience with you.
