Harry Potter SpellCaster 1.2.2
the author of this app says:
Enter the Harry Potter world and become a great Wizard with your smartphone!
**10 NEW SPELLS EVERY WEEK!**
Harry Potter SpellCaster lets you take the robes of a wizard and use the same spells that you read on the books or saw in the teathres. With your fingers and your imagination, you search for the 15 (for the free version) magical symbols that will unleash the power of the spells. The Headmaster himself will guide you in this magical world, and Professor Snape will kindly(?) give you a hint to discover the symbols, if you really need to.
So, grab your wand and your smartphone, and begin your journey to become a wizard!
