500px mobile app is back on the Apple App Store for both iPhone and iPad.

The app has been updated to include a report button that can be used on offensive images.

500px has also fixed some bugs related to logins and photo loads.

The app was removed by Apple for featuring nude photos. Users can still access a dedicated section for adult material after logging in.

We assume 500px is hiding adult material from guest users of the app.

The app is only available to users who are at least 17 years old for the same reason.
