## Most critical reviews (6 lowest-rated)

### 1/5 — Won’t let me add a plus sign

*2023-10-27, version 2.1.4*

Doesn’t allow me to add elements in a formula

### 1/5 — Need more refinement

*2017-10-17, version 1.1.2*

The graphic user interface could be improve.  It is confusing o how to enter the molecular formula and get the molecular weight. There are better apps out there.

The App Elements is much better.  There is a Pro version if you need more capability.

### 2/5 — 🤷‍♂️

*2018-09-15, version 1.1.2*

Doesn’t calculate to the hundredth place, I get that varies but could just use the weight on the periodic table

### 4/5 — Future feature I would like to see

*2023-05-29, version 2.1.4*

I like the interface and history recall.  I would also like to see the ability to use those molecular weights in a calculation for converting a given sample weight of a compound of known molecular weight and finding the molar amount; a common issue in dissolved compound measurements.

### 5/5 — Very helpful, but have two suggestions

*2019-12-12, version 2.0.0*

1, it will be great is we can move the cursor and modify the formula;
2, can you add the isotope information too?

### 5/5 — Very useful

*2017-10-08, version 1.1.2*

Can be helpful doing homework
