ChemTrix is a powerful calculator for common chemical problems.

ChemTrix is the chemistry app youve been hearing about. Its the calculator preferred by discerning chemists, profs, and students who use it every day to get their work done quickly and accurately.

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

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

"This saves me some serious time at work, I cant 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 nearly 100 pre-programmed chemical groups, such as common organic fragments and protecting groups, polyatomic ions, and ligands
- 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.

Pros and cons of ChemTrix Chemistry Calculator app for iPhone and iPad

ChemTrix Chemistry Calculator app good for

Nice and useful app. But its impossible to correct whats typed, we can just clear the whole formula, which is stupid if we only made one mistake.

This is terrific, well designed, elegant and super helpful. Reduces all simple molar calculations to seconds! I highly recommend it.

Quick and clean to use. Its useful for making up problems or checking student work.

I had the choice of either this or extra plum sauce for my meal and I chose this. I do not regret my purchase and I l-o-v-e plum sauce. Most useful app ever.

This is what I expected from Nathan, an awesome application. Easy to use and makes students lives easier.

Super helpful & totally awesome- what a great idea, thank you!

Some bad moments

Now we must all join together to get our teachers to allow iPhones/iPods during tests :P

This saves me some serious time at work, I cant recommend it enough!

I got this app when it was free, and man works great for my Chem class calculating Molar Mass !!!

Helpful for quick reference. Dont like how you cant type in atoms though and have to scroll through a list

Great app so far! One thing that would be awesome is if we could create our own groups. But other than that its pretty good!

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