It's fun I pretty much only get easy questions about rotation axis, reflection planes and "how many sides does this have" I wish you could choose the difficulty because the game gets boring after a while. I also seem to keep getting the same questions wrong. I wish it saved your wrong questions to show you the answer later.
Amazing This app is actually amazing. It explains crystallography better than my text and provides accurate models to test yourself with. Also provides a table with Hermann - Mauguin notation.
Very helpful i love crystallography and i want to improve my skills. This app helps me about a crytals form, structure and many new words in geometry. Thanks
