BetaCompared by the makers of Bring Back Red
For a whole dive, the best underwater color correction app for iPhone is Bring Back Red. AI finds the dive in your camera roll, corrects every photo, Live Photo and 8K HDR clip in one pass, and reopens each export to check it before calling the job done.
Bring Back Red's App Store listing is the only one of the nine that names 8K video, Live Photos and a check of every export. Each answers something a dive hands you: video shot in 4K and up, the Live Photos an iPhone takes by default, and a long export that has to make it to the end.
Every frame is read before it is corrected, so the answer fits that shot rather than a preset, and a photograph whose color is already balanced is handed back untouched. What comes back is what the water took, not a repaint: AI that measures, never invents.
Bring Back Red reads your photo library, recognizes the underwater shots and groups them back into the dives they came from: photos, Live Photos and clips together. Open one and the whole dive is corrected in one pass. Shots that are already balanced are left alone, and only the few it is unsure about ask for a decision.
You open a dive, not two hundred files. It runs on the phone, so it works on the boat with no signal, there is no account to make, and your photos are never uploaded.

A complaint that keeps recurring in this category's App Store reviews is a video export that fails, sometimes at 99 percent. Bring Back Red reopens every export and checks its duration, dimensions, orientation, frame rate, audio and HDR against the source before calling it finished. An interrupted save picks up where it stopped.
The correction follows the clip as the light changes through it, instead of freezing one look over the whole thing. Sixteen export combinations - H.264 and HEVC, SDR and 10-bit HLG and PQ, 1080p and 4K, 24 through 120 fps, portrait and landscape, silent and with audio - were exported and reopened, each matching its source. A corrected 4K 60 fps HLG clip came back with its audio and its HDR intact.
Every tested format, cell by cellDive+ users keep hitting the same wall: the app closes when a clip opens, or the corrected video will not save, often after they paid for it.
Bring Back Red reopens every export and checks its duration, dimensions, orientation, frame rate, audio and HDR against the source before calling it finished. An interrupted save picks up where it stopped, without reprocessing the clip.

Bring Back Red vs SeaRealAquaColorFix, DeepColors, DiveLume and SeaReal each say in their own App Store listing that an unpaid export carries a watermark, and AquaColorFix, DeepColors and DiveLume put video export or full resolution behind a payment: saving video is a Pro purchase in AquaColorFix, 4K HDR export a subscriber feature in DeepColors, and DiveLume's free version stops at 720p.
Bring Back Red exports supported video at the resolution, frame rate and HDR it was shot in, up to 8K, with the audio still on it.
Red read exactly zero between 3.4 and 10.2 meters of water across four dive sites in a public dataset, set by the water and the distance to your subject rather than the depth on your gauge. Bring Back Red measures what the water took from each shot and restores what is still there: AI that measures, never invents.
