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.
For iPhone with iOS 26 or later. No account needed.
What UWGrade does
Every feature is also available without a subscription.
Automatic color correction
UWGrade measures the blue and green in every image, reconstructs lost red and sets strength, brightness, contrast and saturation to suit the subject. Neutral areas don't tip into red.
Camera with live grading
You see the correction while you take photos and videos. The camera works with one finger, even in an underwater housing.
Videos with scenes
UWGrade detects scene changes, corrects each scene separately and applies your trim to the preview, the scenes and the export.
Fine-tuning and presets
White balance, warmth, tint, shadows, highlights, haze, turbidity, red reconstruction and more. Save your settings as a preset.
Crop, follow, stabilize
Straighten photos, trim videos and let the frame follow a subject, with stabilization if you want it.
Full-quality export
Preview and export look the same. Metadata is kept, and you can remove the location. Exports keep running in the background.
