Thanks for your rating and comment Ninja! It's nice to know that you enjoy my app. Unfortunately, my computer crashed some time ago, and I no longer have the source code of my app! So I'm afraid you wont see any updates :(. Perhaps I will start again from scratch and make a new math trick app in the future. Review deleted
