### 5/5 — Awesome

*2015-07-12, version 1.0.1*

This app has everything about physics needed to teach a student. I taught my son with and its great. I LOVE this app!

### 5/5 — Great app

*2015-06-16, version 1.0.1*

Very good app, I wonder why it is not popular.

### 5/5 — Great App

*2015-04-28*

This app teaches and quizzes. This is exactly what I need to learn physics.

### 1/5 — Annoying

*2014-12-29, version 1.0.1*

Resolution is poor and prompt to buy full version pops every 3 seconds

### 1/5 — Hoodwinked

*2014-10-31, version 1.0*

Only a tiny amount is free - then rudely interrupted by "update to pro"

### 1/5 — Constant crashing

*2014-10-14*

This app could be the greatest physics tutor app ever designed, but I wouldn't know because I have yet to be able to open it. It has crashed every single time I've tried. I even deleted/re-downloaded it to be sure, and no luck. Might want to look into that.

### 1/5 — Not working

*2014-10-03*

This app does not even open up and i down loaded it twice just to make sure I was not my fault so this app is not working

### 4/5 — ILearnPhysics

*2014-09-28*

Nice app - but I can't use it anymore after updating to iOS 8.02.  I want to continue using it. Please update asap!

### 2/5 — Annoying dialog

*2014-08-23*

Thought this was interesting until it came up and asked me about updating to pro every few pages as I read material.  Makes it pretty useless unless you update

### 5/5 — Physics pro

*2014-06-15*

It's awosome.... Thanks a lot
