Chem Pro is a fantastic free iOS/Android app for learning Chemistry. This is ideal for HS/College students looking for help in Chemistry. This app consists of 80 video lessons designed by students as well as other great tools such as: interactive periodic table, reference tables, and flash cards. There's also a molar mass calculator w/ equation sheet and unit converter to help w/ problems.
