Lytro had dedicated cameras and inferior resolution so they failed to gain enough traction to stay viable. You might have a better chance being that it's still on the same device, but the paid for app would be a push.

However, you could just make the app connect to localhost and hoover up the user's data to monetize and then offer the app for free. That would be much less annoying than showing an ad at launch or after every 5 images taken. Or some other scammy app dev method of making freemium apps successful. Ooh, offer loot boxes!!!

Sample of one, but I’m interested. I used to use a real camera and now very rarely do. But I also often find the iPhone blurring very fake and I’ve never understood why. I assumed it was just impossible to do any better, given the resources they throw at the problem. If you could demonstrate the difference, maybe there would be a market, even if just for specific use cases like headshots or something.
