If the app is something that will have new features, new content etc. added on a semi-regular basis, then I'd be prepared to pay a small monthly sub.
If it's an app that can't really be 'improved' over time, I'd only ever pay a one-off cost.

I've got a couple of pretty static apps coming soon too but they'll have a small adsense ad on them as they will all be running on devices with no servers / db
