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!!!
