### 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?

### 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.

### 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!

### 1/5 — CMM

*2015-02-26, version 2.2.2*
