Did you have a look at the DMD Panorama app mentioned above? It has recently been updated. In their first paragraph info they mention their new app VRKit. So I went to have a look.
The VR app is free but it requires some hardware, conveniently
-)) available at theVRkit.com. So I went to have a look!
The VR app requires a fisheye lens and after doing lots of tests with the available fisheye lenses they picked one which they sell at a very reasonable price. $12.99US, I think. The fisheye is a 160°.
Also, please note, they have made their own Rotator since the demise of Motrr, their former partner in the pano scene. Their Rotator looks to be a similar size to the old Motrr Galileo and seems to come with its own mini tripod legs(?).
I have written them to find out about two things. They mention their fisheye lens is not suitable for iPhone 7/8 Plus or X, presumably because the entrance pupil of the fisheye lens is too small for the Apple image stabilization, which is also why Moment had to redesign all their lenses.
So far I have found out they also have a new fisheye for iPhone 7/8 Plus but it is still in production and not ready yet for their web site. But they did offer me one of their few early versions. This new fisheye is a 180°.
I wondered if the Moment SuperFish lens (170°) would work and asked that as well.
I also wanted to know if their Rotator is suitable for DMD Panorama. It seems likely to me since the Rotator is connected to the iPhone via Bluetooth just like the Motrr and receives stop/start signals from the app.
Apparently, you can use the VR app manually, just like DMD Panorama. The Rotator just adds speed and precision to photo positions.
Looking at a photo of the Rotator (also a video showing it in action) it has a “U” shaped mount to hold the phone and it looks to be more universal than the Motrr mounts (one of their downfalls). The thing about any of these mounts is that they generally require the phone to be bare - without case. The extra thickness of the case won’t fit. I rely on the Moment case to mount my lenses so there’s a snag already.
The Motrr phone mounts were more complex because the Motrr was designed to do more than panoramas. It also made spherical images which placed the phone in horizontal positions which made the mounting more demanding.
