Basically, my app has no monetization except as a paid app. So making it free is really free. I don't mind missing out now if I can somehow turn it profitable later. Originally, I planned to just make it free for a few days, but it started to take off and I figured a free popular game is more valuable than an unknown paid one. It's in the top 10 in a few countries in its category. In the top 10 in overall games, and in the top 30 or so in all apps overall in Germany. Do I just keep it free and try in-app purchases? I've looked at a few games where a popular game was free, then made paid, and it didn't seem to affect much at all. Of course, these were top 10 games, but it seems like a very gutsy move to me. Anyone with any experience with this? My game is called Cliff Diving 3D. If they like it now, they're going to love it after I've finished with a few updates I'm writing now. Cheers!
