A simple QR code generator that does exactly what it's supposed to, nothing more, nothing less. Create a QR code based on any text, URL, email address, phone number, or anything else, save it as an image in your Photos app and then send it via email, WhatsApp, iMessage, or any other way... And all without any of your personal data being collected, used, or sold. Your data remains your data and stays with you. I develop the "Simple QR code generator" in my spare time. I don't want any money for it (the app is free, there are no in-app purchases, there is no advertising and I don't collect any data), I'm happy when it is used and can help other users in their everyday lives. Unfortunately, errors can creep in during development, in the texts or in the functionality. I try to implement feedback as quickly as possible. If something goes wrong, I would be very happy if you would write me an email before giving a negative review so that I can fix the problem.
