It is good for crystals symmetry practices.
I suggest that you gave some explanation about the answer is to give us some knowledge why.
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.
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.
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

Absolutely perfect app for learning crystallography
Best
Helped a lot
Great app! but crashes a lot and the progress gets lost so you have to restart. would be great if one could choose categories to train. (And my Apple-Friends would love to use the app as well :))
