The ChemBasics app provides hundreds of opportunities to write inorganic formulas, write and balance chemical equations, and perform mass-mass calculations. Immediate feedback is provided with every item. Access to the correct result is a finger touch away. The simplicity of the interface allows the user to focus on chemistry. View animations of app operation and access additional resources at chemistryapp.org. This app runs on IOS 8.4 for iPhone, iPod and iPad. This method of learning or teaching chemistry has been successfully demonstrated on classroom computers over a ten-year period all over the US. This is our fourth app to go mobile.
1) Thirty more reactions have been added to the Mass-Mass calculation portion of the app. There are more than 335 reactions.
2) The states for solid, liquid or gas have been edited to better reflect conditions of the reaction.
3) The in-app calculator has been adjusted to improve handling of significant figures.
With Family Sharing set up, up to six family members can use this app.
