So a couple of things about this app. It looks great, and the quality is nice. However it only works for videos. You cannot take a picture or import a picture and use this app. Also if you try to import your own video, or a live photo, it crashes the app. I’m currently using this on an iPhone 12 pro. It has crashed every time. There’s no way to adjust the matrix code rating speed, color, or size. These should have been, in my opinion, features for adjustments out of the box. Though I wouldn’t change the color myself ;)I would gladly pay another dollar for the app add-on for these features become unlocked or added.Please do so!
