Extract depth data from portrait photos ("Portrait Mode" photos taken with the dual camera from the iPhone 7/8 Plus models or with the TrueDepth front camera from the iPhone X/Xs/Xs Max models). Depth data is saved as a PNG file into your camera roll. Embed arbitrary depth data back into photos, or even into photos that don't have depth data in the first place. Disparity can be used for creating nice 3D effects for sharing on social platforms such as Facebook. By modifying existing depth data and baking back in or adding new depth data into photos without depth data, the possibilities are only limited by imagination. Even though Disparity runs on any supported iPhone without the depth camera, you may be limited to uploading 3D Photos to Facebook only on devices that has a depth camera such as iPhone 7 Plus, iPhone X or newer. This is a limitation of Facebook, not Disparity. In that case, you may send your photo to a supported device and try from there but make sure you send the actual file, not a converted version of it as converting may cause a loss of depth data. Disparity is not an editor, it's just a small helper app that extracts and merges depth data to/from photos. You may use your favorite editor to actually edit the depth data. If designing a depth map from scratch, please make sure that the depth map has the same aspect ratio with your target image. A width of 480 pixels is recommended for the depth map, as anything wider will be resized to fit 480 pixels of width.

This is an application that extracts a depth map image from a portrait photo with depth effect taken with an iPhone, and creates a 3D photo from the original photo and the depth map image. You can adjust the depth effect, rotation, save the created 3D photo in SBS format, and share it with other 3D editing apps such as i3DSteroid.

Verdict
The clearest difference is in-app purchases: Disparity at none against i3DPortrait's 1. Disparity also leads on update cadence (every 10 days vs every 4 months) and rating (4.3 vs 4.0). i3DPortrait's advantage is review sentiment (50% vs 25%). On price, ratings volume, ads and device support there is nothing between them.

Disparity holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 6 and 4 respectively. Written reviews complicate that: 25% of Disparity's written reviews are positive against 50% of i3DPortrait's, so the app with the better star average is not the one people write more warmly about.
Disparity ships an update every 10 days, i3DPortrait every 4 months. Both last shipped on October 24, 2026.
