ChemStud is your companion to the world of Chemistry!
ChemStud is written by a former Chemistry teacher. As a teacher I liked to tell my students that chemistry is easy, algebra is hard. ChemStud knows the equations and can do that pesky algebra for you. Okay but so can wolfram alpha I hear you say. Thats a good point, wolfram alpha is incredible but it can't do significant figures. Everything in ChemStud respects significant figures. That means you don't have to remeber to apply them at the end of the calculation like you would just useing a calculator, phone, or computer.
ChemStud is only $5 and is available on Google Play and the App Store.
