QR code generator

iQrcode G makes QR codes and reads them, in one app. Type a URL, a message or Wi-Fi details and the code appears as you type. Choose the foreground and background colours, the error-correction level, the shape of the modules and of the finder patterns — square, circle, rounded, vertical or horizontal lines — and the border and quiet zone, then export at anywhere from 200 to 2400 pixels. Put a logo in the middle, picked from your gallery or taken with the camera, cropped to fit, with rounded corners or in greyscale if you like. Save the result to your pictures, share it or print it. The scanner reads QR codes and barcodes through the camera, with a flashlight, pinch-to-zoom and an optional beep. When several codes are in view, the picture freezes with a box around each, and you tap the one you meant. Or pick a picture from your gallery and read the codes in it. Links, text messages, email, phone numbers, Wi-Fi networks, places, contact cards and calendar events each come with the action that fits; any result can be copied or sent back to the generator, and recent scans are kept in a history.
