Once you have a 3D scan of your face, you can customize your 3D avatar of yourself from any device. If you don't have a compatible phone, then you can borrow one from a friend. The face scan takes less than a minute. It is sent securely to your email. And then you can customize your figure from any device.
If you heard about Action Face from a school or sports photographer, they can 3D scan you as well. The ACTION FACE SCANNER app is compatible with iOS devices with Face ID - which is iPhone X, 11,12, 13, and iPad Pro 11-inch, 12.9-inch (3rd gen+).
