I had to help a friend to find a qrcode app on Sunday. Look for qrcode in the store, 842 found. Wow... None of them has a review or stars. How do you trust them? We kept scrolling for a while, nothing. Compare that with the Google store. It doesn't tell me how many qrcode apps are there but it gives me a rating for every single one. Then it's the usual hunt for the app with no ads and least permissions, but that's the same on the iPhone.
