### 1/5 — Doesn’t work

*2023-01-16, version 1.0*

I wish the developer would update the app. My son was super excited to try these apps with his books but unfortunately, none of the apps work.

### 1/5 — Apps don’t work- not updated

*2021-12-27, version 1.0*

Downloaded multiple apps from Encyclopedia Brittanica  Virtual Reality Science set None of the VR apps work. The screens VR just spin & spin so it’s wasted money with no customer support that I could find.

### 5/5 — Flickering and spinning on iPhone fixed

*2020-12-25, version 1.0*

UPDATE: After reading the description and solution regarding the flickering and spinning issue, we restarted our iPhones and that reset the app. Now it works perfectly and looks great. 

OLD REVIEW: We tried the app and the screen is flickering. We’ve followed the instructions carefully and tried it on separate phones and two of the separate books from the series. The app is not usable for us. If this isn’t fixed, it looks like the set of 6 books is getting returned to Costco.

### 1/5 — BRUH

*2020-10-19, version 1.0*

IT SAYS IT CANNOT TO THE SERVER WHEN MY WIFI IS FULL

### 1/5 — Blair witch project glitch

*2020-09-28, version 1.0*

When we tried to use it it is just spinning around at light speed and makes you feel like you’re in the Blair witch project. Beyond disappointing.

### 5/5 — Wow

*2020-02-25, version 1.0*

I have learned so much out of this app it is so 
Educational

### 2/5 — Needs more

*2019-01-25, version 1.0*

The app is cool but needs more spaces.  Given the amount of topics in the book it would be worthwhile to have more one space per chapter.  Also audio with the interactive text.

### 5/5 — Works fine!

*2019-01-19, version 1.0*

This app works fine, as long as you follow directions. It’s pretty cool!

### 1/5 — App does not work

*2018-12-27, version 1.0*

Unable to scan a QR code.

### 1/5 — Says invalid QR code

*2018-12-25, version 1.0*

Christmas morning... and the apps for the new toy don’t work. Not cool. Not. Cool.
