Great app
Works well would recommend. It would be a really cool feature if you could name the elements too. It would also be cool if you could type in “oxalate” and get the percentages of oxygen and hydrogen instead of having to search that oxalate is OH and then putting it in.

Super time saver!
I’ve been using this formula mass calculator for years. I am a chemistry prof and I find that it saves a lot of time when I’m writing new notes. I tell my second year students to go ahead and just use it to save time. I don’t tell my first year students. LOL.

Well done
I'm a chemistry prof, and this saves me a lot of time. At first, I didn't like that proper capitalization was required, but that does eliminate ambiguity, and I expect that degree of care from my students when they write chemical formulas. Many of my students are now using this, too.

Easy to use and helpful
This app is amazing! It makes calculations so much easier, and is very accurate. Especially helpful if missing a periodic table or if you want to do quick calculations from formulas. 10/10 for any high school or college student in chemistry.

Thank You, App Author
This brilliant little app quickly -near instantaneously- calculates the molar mass of just about anything you'd care to name. Much quicker than anything on the web and incomparable to doing it by hand. Thanks much, author, you've saved me tonnes of time.

Excellent app!
This app is great! I really like the update with the integrated calculator. However, when pressing the number 7, it registers a double press, so it puts in 77. A minor annoyance for an app that's so helpful!

Pretty good
Not bad, really annoying when you have to capitalize specific elements. But in all honesty an excellent aid in solving homework problems.

Nice App
Why my chemistry students don't put this on their iPhones is beyond me. Works perfect and I verified a few results with a current periodic table.

Great App
As a Chem teacher, once students learn the theory & practice calculating molar mass "by hand" this is the App I recommend they download. It just works.

Only criticism is that you have to enter capital which take time

Does great
Takes the time consumingness out of chem. Molar masses are easy but meticulous. This solves that problem! Pas problème! 

8 years ago, It was a nice thought
Could be useful
This app could be pretty useful; however, most of the masses for several key elements are incorrect, rendering this app almost completely useless. It's a nice idea, though.

@SulleyBear24: In English, at least, you’re correct.
@SulleyBear24: In English, at least, you’re correct about the acronym. But you’re not correct about that in Spanish or French, in which the app might originally have been created. So, is that the only reason you panned this app with a 1/5 star rating?

a Handy Tool
A handy tool to determine percent of the weight of fertilizer to give a needed mass of an element. You can copy and paste the block of results like this: H 5.376% Cl 31.517% O 42.669% Na 20.437% Neat. Pete

It seems really good but it doesn't recognize Florine and that makes me wonder if there may be any other code typos???
