Stunningly helpful and beautiful – EleMints: Periodic Table Review
Simply the best periodic table app out there. Awesome sorting features in the table itself plus a crazy amount of statistics and information for each element. The equation balancer is an excellent tool for students to learn, and the Wikipedia article links add so much information when the app can't always help (a situation you probably won't ever encounter). Plus, beautifully designed for iOS 7.
