Aside from all the little quirks of MyApp N+1 (multiple versions of the same app installed, new users accidentally buying old versions), there is one major flaw

• derefr 12y ago
  If you charged $20 for both MyApp N and MyApp N+1, and made up the $80 difference in version-portable IAPs, then you'd get the pricing model you're suggesting. A good candidate for this would be something like Photoshop, where $20 would get you the "engine" of Photoshop N, and then you pay $5 each for various brushes and filters. When you upgrade to Photoshop N+1, you're upgrading to a new engine—but keeping your brushes and filters. Games could also work like this, though in that industry, the more common strategy is the "expansion"—effectively, keeping an entirely new version of the app logic/assets commingled with the old version but disabled using feature flags, and then unlocking it through an upgrade-priced IAP. (Now there's a thought. Could you ship two entirely separate binaries within one application bundle, and put a switch in your app's prefpane to toggle between execv()ing N or N+1?)
