how to.. 2 channel bluetooth motor control

yes I must be both android and iOS.
Not need for speed feedback.
Packaged in an ABS box.
Powered 12v.
Motors will be driving wheels (buggy for my boy).
Environment... clean. Smooth and dark.

Experience... I’ve made many things with these motors and controllers before, but never Bluetooth. Almost no experience with Arduino.

Thanks for your help, really appreciate it.
