SmogScanner vs Smog Pro

SmogScanner and Smog Pro are both work order and invoice software for California smog stations. Smog Pro runs in a phone or tablet browser with appointments built in; SmogScanner is a phone app that shows which smog test the car needs on every scan.

Can I bring my customers over from Smog Pro?
