Two Mobile Apps that I think are useful for college students are chegg and mathway.

Chegg is like the bestfriend to all college students. They have great prices for new, old, or rental textbooks. They are also willing to match prices with competitors. This is awesome because as college students money is already tight, so this allows you to spend less on textbooks. College bookstores are normally expensive so Chegg is normally the best option. They aklso great for renting because some students might only need a certain textbook for the semester.

Mathway is a great app for students who need more help in math. Once you put in the formula it gives you step by step instructions on how to solve the problem. Some students need visual explanations and this is the perfect tool for them.
