ChemTrix is a powerful calculator for common chemistry problems.

5 stars! "Easy to use, intuitive, and exactly what I expected from the description; by far one of the most useful chemistry apps I've found."

5 stars! "It is easy to use and super helpful, saving hours when doing those sheets of long, tiresome equations in AP chem."

5 stars! "This saves me some serious time at work, I can't recommend it enough!"

Other chemistry calculators make it hard to do simple things. Not ChemTrix. ChemTrix was built by chemists, for chemists. It has powerful, convenient, time-saving features that make common chemical calculations a snap.

Enter a chemical formula, and ChemTrix calculates:

- Molar mass (molecular weight)
- Exact (monoisotopic) mass
- Most probable mass
- Isotopic mass distribution
- Percentage composition by mass
- Mass-moles-molar mass relationships (including unit conversions)
- Moles-volume-concentration (molarity) relationships (including unit conversions)

ChemTrix features:

- Quick, simple, and accurate formula entry using a purpose-built keypad, including programmable buttons for even more flexibility and speed
- Natural chemical syntax, including over two dozen pre-programmed chemical groups
- A history of all entered formulae, any of which can be incorporated as fragments into new formulae​
- User-defined abbreviations for any formulae
- Detailed listings of the properties of all the elements in the periodic table, including electronic configurations, isotopes, electronegativities and more.
