Ah thank you guys

I guess Tagger is what I was looking for, as QR Maker seems to only make the codes but is not be able to read them? The description says: "qrmaker is a qr maker it makes qr codes"

Hi guys,

do any of you an app on Ubuntu Touch for reading and creating QR codes?

I'm still new to Ubuntu Touch and Smartphones in general.
So I apologize if the answer should be obvious to me.
