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. ### 5/5 — Useful *2014-02-21, version 2.2* It is so useful and such a great tool to use! ### 5/5 — Great *2014-01-26* This app makes doing Chem homework so much easier and quicker. ### 5/5 — Great *2013-11-12, version 2.2* This app really helps with my AP Chem homework ### 5/5 — Excellent! *2013-10-24* Great app, I love it! Only issue I have is having to press the shift key all the time. I would love it even more if the default text entry was in capitals. ### 5/5 — Very great app, makes accurate calculations *2013-10-20, version 2.2* Highly recommended ### 5/5 — Excellent app! *2013-09-05* 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! ### 5/5 — Easy to use *2013-08-06, version 2.0.1* Very easy to use. Would really like to see a molarity calculator included! But great for quick referencing of molar mass ### 5/5 — Great job *2013-04-22, version 2.0.1* Does exactly what I need it to do. ### 5/5 — Évaluation de ccm *2013-04-17, version 2.0.1* Excellent app. ### 5/5 — ME *2013-04-10, version 2.0.1* Great app ### 5/5 — Thank You, App Author *2013-03-12* 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. ### 5/5 — So awesome and helpful!!! *2013-03-06, version 2.0.1* So awesome and helpful!!! ### 5/5 — Omg awesome!! *2013-02-21, version 2.0.1* Great!! Love it so easy ## Most critical reviews (10 lowest-rated) ### 1/5 — Name *2017-12-05* The name doesn’t match up with the acronym. ### 1/5 — Could be useful *2015-10-20, version 2.5* 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. ### 1/5 — CMM *2015-02-26, version 2.2.2* Not Up to Date ### 1/5 — Oh my gosh *2012-10-11, version 2.0.1* You guys are nerds. ### 2/5 — Good for gen chem only *2014-10-23, version 2.2.2* Really wish this did mono isotopic mass Also, iOS 8 keyboard covers up the mass on my phone (4s) ### 2/5 — Great! *2012-07-18, version 2.0* Very handy when doing calculations ### 3/5 — Update *2013-02-06, version 2.0.1* It seems really good but it doesn't recognize Florine and that makes me wonder if there may be any other code typos??? ### 3/5 — Useful *2011-04-12, version 1.0* Pretty helpful app for all my chem needs. Problem is that it doesnt recognize the elements if you type them in lower case. It would be nice to have an actual periodic table to tap too. You don't need to know french to use this app :) ### 4/5 — a Handy Tool *2015-01-03, version 2.2.2* 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 ### 4/5 — Easy to use *2013-04-24, version 2.0.1* Simple app, works great. ## Most praised reviews (10 highest-rated) ### 5/5 — I Love This App! *2022-10-14* This helped my chemsitry class! ### 5/5 — perfect *2022-01-27* Does exactly what I need it to do. Great time saver. ### 5/5 — Super time saver! *2020-08-24* 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. ### 5/5 — Great app *2018-11-14* 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. ### 5/5 — @SulleyBear24: In English, at least, you’re correct. *2018-11-04, version 2.8* @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? ### 5/5 — GREAT APP *2015-04-21* thank you for making my science homework 100x easier! ### 5/5 — Great! *2015-03-22* Easy to use and always correct. Extremely convienient for chemistry students! ### 5/5 — Nice *2014-09-25* Very nice little app. No unnecessary extras. Fast and simple design. Well done. ### 5/5 — Great app *2014-08-20, version 2.2.1* This app is very versatile in calculating chemical masses, complexes, organic molecules etc are easy to find the masses for . ### 5/5 — Collegiate Gen Chem *2014-04-01* This is app is accurate and easy to use. I haven't come across any bugs. No complaints here, thank you for this useful tool! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
