How do you plan to handle the transitionfrom free to subscription? Once you price yourself at 0, it can be very difficult to convince users to start paying for what was once free. I would generally recommend avoiding having a free period entirely, and instead offer an early adopters discount as well as a free trial period. Since it sounds like you missed your chance on that one, I would look for ways to offer both a free and payed version. Again, the difficulty here is that once something is in the free version, you want to avoid removing it, so you will need compelling new feaures to make this work. You also need to make sure that the free version continues to leave a good impression. Having said that, I suspect you will find there is a reason so many companies end up monetizing through avertisements...
