I'm going through a similar exercise right now in an app I'm building. No server dependencies, for features that have traditionally used server side APIs, moving those capabilities onto the device. And also utilizing the on-board AI features provided by Android and iOS. So far it's been a very positive experience, and the capabilities provided on these devices have been more than capable for my needs. Working on providing apps that don't have ongoing operation costs of running server side infrastructure, so I can offer them as "pay once, run it forever" instead of ongoing subscription costs for the user.
