I have never paid for a game app before, but I guess I can't help myself with Propeller Dog Pro. I really enjoyed the lite version of the game, so I was totally curious when the full version came out. It was available at $0.99 on the iTunes Store. The reviews were really good and the screenshots were practically wooing me to download it. I had no choice. I broke my own rule of not paying for any app. Good thing Propeller Dog Pro was totally worth it.
