### 2/5 — Not free!

*2021-08-28, version 2.0*

Only one function is free. The rest is not.

### 1/5 — Full version

*2021-07-15, version 2.0*

It doesn’t register as I have unlocked the full version

### 1/5 — Horrible app

*2020-07-01*

You have to buy everything. 
The only thing free is the heating/cooling system

### 1/5 — Contains only 1 simulation

*2020-06-03*

Its merely the cooling system youll look at... nothing else. 

Pay 6.00$ or delete the app

Simple

### 1/5 — NOT FREE

*2016-08-10, version 1.87*

Sure...you can download it for free, but anything you wanna look at will cost ya money. Wanna see how the braking system works? $3.99.  Do yourself a favor and don't waste your time or money on this app. Watch a YouTube video for free.

### 1/5 — Mr

*2016-01-29, version 1.87*

Poor quality, poor information!poor graphics..just poor

### 4/5 — Great concept for visual learners

*2015-11-01, version 1.83*

This really provides the user freedom to learn how each sub system works together in unison. The only problem I had was trying to change the view. The zoom and rotation sensitivity was extremely high so I spent more time trying to get the component I wanted to learn more about, than actually reading about its functionalities.

### 5/5 — Great idea

*2015-08-26, version 1.81*

Like idea of interactive animatins. Very interesting and helpful.
