I am not a fan of this but, I think that this is the way that things are going with apps. Apple does not have a way for developers to offer payed update for major updates. They are offering the subscription for 50% off for the 1st two weeks it's in the App Store. That is for as long as you keep the subscription active. It would be a good time to start LogTen Pro. I say this is Apple fault not Coradine. They have to make money and they can't do that giving updates away.
