MOSAQO TOOL
Free QR code tools
Two small tools for the questions that come before a code is printed. They run in your browser and need no account.
QR code size calculator
Work out how large to print a QR code from the reading distance, the length of the destination and the conditions it will be scanned in.
Google review link generator
Turn a Google place ID into the link that opens the review box. No account, no install, and the address Google itself documents.
