### 5/5 — does what it says

*2023-07-07*

weird that i had to scroll as far as i did for an app that would let me generate qr codes. this app lets you easily do that. none of the other apps i downloaded allowed for that, even though they purported to be qr code apps. 5 stars, does what it says it does.
