The app is fully optimized for both mobile phones and tablets, so regardless of the type of device you use, the interface will adapt nicely. On each user's profile, you can see the user's photos and also the camera and lenses that he or she typically uses.
When you look at another user's photos, you can see details such as the camera model, lens, shutter speed, and aperture. You can also comment on any photo just as other users can comment on your photos.
As expected, 500px lets you upload your own photos from your Android device. The app will automatically detect the image's information, but you can fill in additional data manually.
500px is a good photography app which is mainly geared towards serious photographers who want to share experiences, tips, anecdotes, and - of course - photographs.
