Naughty or Nice Photo Scanner is a fun photo scanning app designed to help you quickly check if any pictures on your device might be considered inappropriate. I downloaded it from Google Play a few months ago when I was cleaning out my gallery and got curious. It's a free app to install, and it launched a couple of years ago. You can find it on both Google Play and the App Store, and it has over a million downloads on Google Play alone. You don't need to register an account to use the basic features, which is great for privacy. The app does show ads, but they aren't too intrusive. There are also optional in-app purchases if you want to remove the ads or unlock some extra scanning features, but the free version works perfectly fine for a quick check.

Using the app is super straightforward. After you install it, you just open it and grant permission for it to access your photos. Then, you can choose to scan your entire gallery or select specific folders. The app uses its algorithm to look through your images. It gives each photo a simple "Naughty" or "Nice" rating. From a user's view, it's less about perfect accuracy and more about a fast, automated first pass. A simple tip is to not take the results too seriously—it's a tool for fun and a quick filter, not a definitive judgment. I usually use it to quickly sift through old downloads and memes to see if anything obviously sensitive got saved by accident. It's much faster than looking at hundreds of pictures manually.

Compared to other similar gallery cleaner or duplicate photo finder apps, Naughty or Nice Photo Scanner has a very specific, simple job. Other apps might help you organize or find similar pictures, but this one is all about that one question: is this photo potentially inappropriate? I chose it over others because it's direct and doesn't try to do too much. Some apps are bloated with features I don't need. This app is simple. You scan, you see results, you decide what to delete. It's a casual tool for a specific worry, especially if you share your phone or tablet with family. It gives you a bit of peace of mind without being complicated.
