Good App, Bad Service – PRO CHARTS - Marine Navigation Review

I don't use this app very often, but when I need it, I have excellent maps at hand. It's easy and practical to use. The reason for the one star rating is that I've already purchased this app. Now they tell me I have to have a subscription to it. Why do I have to subscribe to something I've already bought? I don't get it. Anyway, I'll use it until I'm required to subscribe then I'll find something else to use. And my original purchase will be wasted. Nice.
