In our case we only need one or two licenses.
Combine the “full price up front version” with the new unlisted apps Flupsi mentioned and it seems like a great solution!
Apple released a Techtalk recently called Explore Unlisted App Distribution that has more info but from my quick read of the transcript I think it would suit this purpose well. Unlisted apps are available to the public (if you send them the special link) and to business/school customers.
So you’d end up with 2 or 3 apps:
- Photon 2 - Regular app, free with IAP, listed in App Store (95% of customers use this)
- (Optional) Photon 2 Starter, $39.99 up front, unlisted
- Photon 2 Pro,
$99.99 $69.99 up front, unlisted
People will keep discovering the IAP version though your website and the App Store and try it out. If any schools, churches or others try it out and then ask on your forums or via support about a paid up-front version, you just send them the link(s) to the Unlisted versions and let them buy it that way.
