There are a few apps right now that runs offline A.I. (instead of in the cloud) using the new CoreML in iOS 11 from Apple, including general object detection as well. But NSFW is a special unique use case.
Guess when you are a third party app running A.I. across entire user album you can't really do cloud anymore.

Yes I am aware of the Nude app and they launched about 3 weeks ahead of us. However, we think our app is much faster, more reliable and customizable. I am positive that you'd see a difference once you've tried both :)
p.s. we NEVER update any of your photos! All scannings are done locally on your own device.
You actually can switch off cellular access of a certain app. You can also use airplane mode while you're using our app. We actually encourage our users to turn on airplane mode while using our app, because we want them to know it absolutely does not use the internet to scan your photos :)
I have never heard about both apps, but after a quick look in the App Store I read that Nude App has Break-In Alerts; the app takes photos of intruders and tracks break-in attempts. It seems like Orga does not have the same feature.
