Add me to the list. I question some of the app subscriptions I do pay for, and those offer a ton more functionality for the same $20-ish dollars. This app doesn't even have a cloud server backing it, no way I'm paying a subscription at all for a utility app with no recurring infrastructure costs.
But to be more positive: I'd love to support an app like this, which I probably wouldn't even use that much these days; I just won't pay the current pricing.
