But here's the thing: if I really like it, and you have any business sense whatsoever, then I'm going to want a subscription. But if I don't know up front what that subscription is going to cost, then I'm not going to bother to download an app, figure out how it works, get really into it, and then find out that the functionality I'm going to want long-term is $895/year.

It also makes me think you're not telling me for a reason. I guess I've purchased too much "enterprise" software over the years. :-)
