ZPlayer3D

Without the need for any special add-ons, this app automatically converts any of your videos into one with 3D spatial effects, the intensity of which can be adjusted by you.
What's more, with eye-tracking information captured by the camera, the app could enhance the precision of 3D reconstruction for the area you are focusing on.

To put videos into the app:
1. Open Finder(for Mac with OSX 10.15+) or iTunes on your Mac or PC.
2. Connect your iOS device to your computer using the USB cable.
3. Click your device on iTunes/Finder.
4. Click the 'File Sharing' or 'Files' tab.
5. Select this app from the app list showing afterward.
6. Drag and drop video files from a folder or window onto the Documents list of the app to copy them to your device. You can also do file deleting in the Document list.
7. Refresh data in the app.
