## Most critical reviews (10 lowest-rated)

### 1/5 — Don’t bother

*2021-11-13*

It’s doesn’t work at all

### 1/5 — Just terrible

*2019-04-21*

I try to put protons + neutrons +electrons but it just doesn’t work!!!!!!😡😡😡

### 1/5 — DOES NOT WORK

*2017-09-19*

this app doesn't even work, you can't drag and drop anything this is rip off and so is the paid version. Find another app!

### 1/5 — Unoptimised and pointless

*2017-05-16*

Bad UI means is very difficult to select elements.
 Pop ups don't fit in iPhone 7 screen properly.
Clunky and not very educational.

### 1/5 — Doesn't work

*2016-08-28*

Can't drag protons, electrons, or neutrons to create the atom.

### 1/5 — App stinks

*2013-03-30*

If you want a good one, get the app nuclear. But this is stupid and a waste of 7.1 megabytes.

### 1/5 — Not right

*2012-10-25*

They mixed up the neutrons with the electrons

### 1/5 — Worst app ever.

*2011-10-02*

The guys how made it are nerds.

### 3/5 — It’s hard and it’s the only game with ions and isotopes

*2019-04-10*

It’s hard to drag and drop and not only that but the fact that you HAVE TOO SOEND MONEY just for to get to be able to make your own isotopes and ions is just annoying and this is the only game where it features ions and isotope abut you have to spend money to build isotope sand ions

### 4/5 — Pretty cool

*2013-06-28, version 1.0*

I like this app. I need practice building atoms so it'll really help. 

The only problem that I have is that I can't get the trash can to work, but other than that it seems to be perfect for what I need it for. 

I also kinda wish that there was a way to see info on what you're trying to build. Like gold could be: "Considered a precious metal. Used in electronics." Stuff like that. Just to make it more interesting, y'know?

### 5/5 — Yea

*2013-07-10, version 1.0*

So good

### 5/5 — 

*2011-10-07, version 1.0*



### 5/5 — Outsidedabax

*2011-09-29*

I wish I had this when I was in school!

### 4/5 — Good Practice

*2011-09-12*

I'm currently taking Ochem and this is good practice if you are having some trouble with electron configurations. 

Con- you can't choose specific elements you want. Maybe cause it's the lite version. I hope you can do this in the full version.
