The Thank You App will work on all iOS devices and android devices.
The recipient does not need to have the Thank You app installed on their device to view the message. The recipient will use the same app they use to scan any QR code on their smart device (usually the camera app on the smart device). Once the recipient scans the code a webpage will load with their Thank You message.
You will be instantly notified in the Thank You app that your Thank You message was viewed by the recipient.
