## Most critical reviews (3 lowest-rated)

### 1/5 — Not worth it

*2013-05-02*

Not even worth paying $2 for this app

### 2/5 — Frustrating to use

*2012-04-03*

Great idea, but I have to tap the electrons protons and neutrons many times before they will drag - so frustrating that I won't use the App....

### 5/5 — Very good app

*2011-05-23*

This app would be even better if you could create more shells and up to 9999 value for atomic #s and mass. Can you please make this adjustment thanks. One thing it locks up sometimes with the iPod when dragging e- p+ n in the atom.
