## Most critical reviews (7 lowest-rated)

### 2/5 — Critical error

*2014-01-02*

No sound on ipad 3 and no landscape viewing. Once this gets fixed I will review the content. As of now app is unusable.

iPad 3 sound works now but the full screen does not work yet in Landscape mode. 

On first generation ipad mini their is still no sund and the same full screen landscape issue. 

In addition the chapter sections do not work either for either device and never have. I forgot to mention that in my first review.

### 2/5 — Freezes

*2011-11-16*

Until it's patched, the app freezes on a white screen after any video.  Stay away until they fix it.

### 3/5 — Some bugs

*2011-11-09*

Good explanations of techniques but I found the app buggy. Problems exiting and running app again.

### 4/5 — Buggy with the new IOS 5.

*2011-10-21*

It is a very good app with good explanation.  However, with the new IOS 5, when you play a video and go back to the title menu the screen goes all white.  Please patch.

### 5/5 — Excellent App

*2012-08-27*

An excellent demonstration of positioning, techniques and training principles for honing your ground game and advancing your skills in BJJ. Well done

### 5/5 — Bjj 101 volume 1

*2012-06-06*

Yet again, Roy Harris delivers a beautiful tuitional app! You don't get millions of techniques from this. You get understanding of how the art functions and why. Buy, buy, buy! You won't be dissappointed!

### 5/5 — Classic Harris

*2011-09-22*

Fundamental bjj!  A must buy app for any serious bjj practitioner.  Simple and effective techniques to develop a great positional awareness!
