### 5/5 — Perfect for chemistry!

*2023-11-28*

Best app yet for calculating molar mass! Simple and easy to use!

### 5/5 — Awesome Molar Mass Calculator

*2023-11-19*

This bad boy will straighten your molarity right out. Super modern design delights the senses. My chocolate cake has never tasted better.

### 5/5 — Must have for chem class.

*2023-11-18*

This app is awesome and just what I was looking for! It helps me find the molar mass of any substance quickly and accurately. Simple to use interface and can use across any of my devices. It is a must have for any chemistry, student or enthusiast.

### 5/5 — Take my money

*2023-11-14*

This app works so cleanly.  Just type in your compound and this app will effortlessly give you the molar mass.  Just gotta be careful to use the proper symbols for the elements, if you type in ZN, you’ll just get the molar mass for nitrogen.  If you want zinc, you have to type in Zn.  I don’t have a problem with this, as you should be using the correct symbols anyway.

The app even allows you to adjust the values to whatever significant digits you require.  Very nifty.

It works flawlessly on my iPad with an external keyboard, once you are running iOS 17 at least.  

Great job Dr. Phos!  Wish I had this in high school/college!
