If you've got NSFW (read: nude) pictures of any kind on your smartphone storage, chances are you don't want them to be seen by just anyone. And while there are apps that allow you to move private images into protected locations, this tends to be a largely manual process... well not anymore.
The so-called 'Nude' app automates the process of finding and hiding your most ... sensitive images.
The app scans your device for nude images using artificial intelligence. If any files are detected, they are immediately moved into the app's protected vault and deleted from the camera roll and iCloud. Under iOS 11, image recognition is undertaken on-device but under iOS 10 and older operating systems data has to be transferred to cloud servers.
The makers of the app say Nude is also useful for keeping images of ID cards, credit cards and other important documents in a safe place, but there is no mention of an automatic detection function. The app is protected via PIN or Touch ID, and records any attempts to access your photos. There is also an integrated camera, so images can be recorded directly in the app.
The app is free to download on the Apple App Store, but requires a $1 monthly or $10 annual subscription to use. For now, Nude is only available for iOS devices, but an Android version is under development.
