If I plan to use Prana Breath on a few of my devices, should I buy Guru version for each one of them?
No, you should not. In order to have Guru version activated on your another device, you just need to be logged in the very same e-mail account you've used while purchasing the app. As you log in, restart Prana Breath completely, swiping it out of "Recent Apps" list. Then you will be able to use Guru version on this device as well.
