Introducing the 1Password App Extension for iOS 8 apps

How many times am I going to have to re-buy this app? I would love to just buy install it once for each device and then pay a subscription and have the versions all just update everywhere. As it is right now I only use it on my laptop because I still have not upgraded on my iOS devices and the sync between v3 (the version I own for iPhone and Mac) is not that great.

Are there alternatives to this situation? I can't go back to not using a password manager.
