### 1/5 — A ducks quack doesn't echo

*2013-03-27, version 2.0*

I think you'll find that is a myth that is untrue. Uninstalled.

### 3/5 — Great

*2013-03-18*

It's  great, cool facts, would rate it 5 star If u guys update it frequently

### 1/5 — Wrong

*2013-02-12*

These facts are either pretty common knowledge, or completely wrong. Most are lies that just gained popularity on the Internet. Remember kids, the Internet tells you everything is the truth if you don't mind where your looking. Just as this apps sources :P

### 4/5 — Fact checking

*2013-01-29*

Elvis Presley's twin brother DID die shortly after they were born, but his name was Jesse Garon. Aaron (or Aron, depending on if you check birth or death records) was Elvis's middle name.

### 1/5 — Terrible

*2012-12-02, version 2.0*

So many mistakes! Any app providing "facts" must, as a bare minimum, be checked and accurate. This app is neither. Anyone who reads it without checking the validity of said "facts" will not learn anything and in fact be dumber as a result.

### 1/5 — False false!

*2012-11-19, version 2.0*

in australia it is forbidden to read horoscopes - rofl

### 5/5 — Wow

*2012-11-16*

This app guesses my password

### 5/5 — Muy padre or very cool

*2012-01-19*

I know about all
