There are and the list is always growing. Google maintains a list of those who are certified by them for various different types of protocols and we choose to focus on utilizing the Eddystone-URL frame because we can do all of the security that Eddystone-EID provides within our BKON firmware and we think push messages from iBeacons and possibly UID are just bad for users.
All of the Eddystone-URL beacons listed on Google's site are compatible with PHY.net as long as they are configured to broadcast Eddystone-URL protocol. Our BKON beacons are configured for Eddystone-URL by default so there is no need for a configuration app ... we do have a configuration app if you decide you want to change the default hardware configuration, though. For info on our configuration app called BKON Connect Configuration app, check out our tutorials and app docs.
