If you want to go through the Google Play store, then you'll need to use different email addresses through Google Play. If you purchase through my FastSpring store (https://zubersoft.onfastspring.com/), then you'll get a license key that can be used on a single device.

As far as the pedal, what matters is the pedal being paired with the device. You won't get crosstalk between the two pedals, so you don't really need to worry about that. If each pedal is paired with a different tablet, they will operate independently.
