Qreator lets you create QR codes in Ubuntu. You can choose to encrypt an URL, text, a location or a wifi network. Of course, there are many mobile apps and web services that let you do the same, but an Ubuntu desktop client cant hurt. Furthermore the options to encrypt not only an URL or text, but also a geolocation or the information about a wifi network are something that goes beyond what most services offer. Qreator is fast and easy to use and pretty straightforward, offering a nice, seamless experience for the user. For further information check out the Ubuntu app directory info on Qreator or follow our download link directly to the Ubuntu Software Center:
