Very limited, and deceives you of its price
This is a mediocre app with absolutely zero customization when it comes to the QR code specification. It does not allow you to change the amount of error correction, does not allow you to change to different input mode encoding (numeral, alphabetic, binary, kanji), and are unable to change the byte/character size of a given QR code. For scanning QR codes, it works fine, but Apple has already implemented a native solution with-in the camera app. Overall, this app is very useless if you want to do anything more than what the company has decided the consumer would want, which is very little. WARNING: a huge trend in cheaply made "free" apps is to only allows users to try it one time, before locking its features behind a pay wall of two dollars. This app psychologically manipulates you to be more susceptible to buying irrationally, by softening you up by enticing you with a free app before making you pay for it. Whoever at this company decided to lie to its consumers is questionable at best, and malicious at worst. Please be more honest and just list the app on the App Store as two dollars, even if Apple takes a cut of that money. Companies like these make people complacent to downloading free crappy crap instead of paying for good programs, therefore ruining the FOSS community, and any individual developer or small dev team who does not play quick and dirty with their competition. Devs need money to be able to develop a single great application, and this company are anti-competitive by flood the market with a hundred bad apps. Making a big application like Nextcloud, Gimp, Audacity, Obsidian. or any other liberated FOSS software is expensive to make, and we need normalize paying for good software, that is what GPL is for. We need to normalize paying for mobile games and applications, because the alternative is paying via ads, letting ad companies steal your personal information, and games having lots of excessive micro-transactions.
