For divers, snorkelers and underwater photographers

The colors of the sea, the way you saw them.

Underwater, the water absorbs red first, then yellow. UWGrade detects blue and green casts in your photos and videos and restores the colors automatically. Right while you shoot, or later in your library.

Google Photos: only what you choose

Connecting Google Photos is optional. UWGrade uses Google's own selection page (Google Photos Picker) for it. The app sees only the photos and videos you select there, never your whole Google Photos library.

UWGrade only reads the selected media. The app uploads nothing to Google and changes nothing in your Google Account. It saves edited results to the Photos app on your iPhone.

The Privacy Policy explains which data is processed.

Your photos stay on your iPhone

UWGrade edits photos and videos on your iPhone. There is no UWGrade server, no account, no advertising and no analytics.
