CoralFix: Underwater Photo Restoration Bring your dive photos back to life. CoralFix restores true colour in underwater shots with one tap. Fix the blue-green cast, recover reds and oranges, and dehaze murky reef, snorkel, and pool photos without an over-edited look. WHY CORALFIX Underwater light fades colour fast. What looked vivid on the reef often comes home flat and blue. CoralFix is built for divers, snorkellers, and underwater photographers who want natural results, not heavy filters. ONE-TAP RESTORATION Pick a photo from your library, tap Restore, and CoralFix applies automatic dehaze and colour correction tuned for underwater scenes. SEE THE DIFFERENCE Compare before and after side by side. Check skin tones, coral colour, and clarity before you save. FINE-TUNE YOUR LOOK Adjust strength, warmth, and clarity when you want more control. Keep it subtle or push the correction further. EXPORT AND SHARE Save restored photos back to your library and share your best shots from every dive. WORKS WITH ANY CAMERA GoPro, action cam, DSLR, mirrorless, or phone. CoralFix handles common underwater colour problems across formats. BUILT FOR REAL DIVERS Designed for reef trips, pool training, snorkel holidays, and everyday underwater memories.

DiveTone

Bring underwater color back to life. DiveTone is a color-grading tool for divers and underwater photographers. Instead of placing one filter over the entire image, it responds to underwater light, water color and subject position—bringing clarity to your subject while preserving the depth and atmosphere of the water. 【Start in one tap, then fine-tune】 ・Vivid, Natural and Classic one-tap looks ・Adjust temperature, tint, saturation, exposure, dehaze, contrast and detail ・Grade background water independently without recoloring the entire sea for the subject ・Save your own custom looks and quickly apply them to the next photo 【Treat subjects and backgrounds separately】 DiveTone uses on-device subject recognition to help find key objects while letting you see and edit the actual area. ・Manage up to three subjects ・Adjust exposure, temperature, tint, saturation, contrast and detail separately for each subject ・Add or erase areas with a brush and use assisted edge tracing ・Create a black-background effect with adjustable strength from the subject mask 【One workflow for photos and video】 ・Use the same underwater color-grading approach for both photos and videos ・Create video segments for changing depths, lighting or scenes ・Export a complete video, merge segments or export segments separately ・Capture a frame at a precise time and continue editing it as a photo ・HEVC output preserves source resolution, frame rate and audio 【Organize an entire dive trip】 DiveTone is more than an editing screen. It is also a project library for underwater imagery. ・Manage photos and videos in one place ・Organize and sort by capture date, date added, location or format ・View GPS-tagged dive media on a map ・Batch-export multiple photos ・Review photo information and adjust capture time and location 【Keep originals safe and your work private】 ・Color grading, subject recognition and mask processing run on your iPhone or iPad ・Media downloaded to the device can be edited without an internet connection ・Apple Photos integration does not create another copy of the original in the DiveTone project library ・The photo workflow is non-destructive; deleting a DiveTone project does not delete the original media from Photos ・When a RAW pair is available, DiveTone reads the original RAW first and lets you retain or remove capture information 【Try every editing tool for free】 ・The free version includes all editing and preview features with no official DiveTone watermark. ・Export 15 distinct photos and 2 distinct videos per day; repeat exports of the same project on the same day do not count again. ・Upgrade to DiveTone Pro to remove the daily limit. Pro is a one-time purchase, not a subscription. ・Ideal for scuba diving, freediving, snorkeling, underwater photography, and organizing underwater photos and videos directly on iPhone or iPad while traveling.
