QR Scanner - No Ads

Scans all QR codes without inserting any additional ads, and there's nothing to buy.
The author of this app wrote this QR Reader after getting really annoyed with all the other QR Readers in the App Store. This app just scans QR Codes, without inserting any additional ads into the content. There are no in-app purchases, all features are unlocked, and there's nothing to buy.
If the QR code is a website URL, the website will be opened within a browser, without inserting any additional ads.
If the QR code is an email address, an email compose window will be opened allowing you to write an email to the recipient specified in the QR code.
Otherwise, if the code is neither a website URL nor an email address, the actual decoded text is displayed.
In all cases, all previously scanned QR codes are displayed in the History tab.
There are no ads, and there's nothing to buy! Seriously!
