If you want to get smoothest stitching on the Xiaomi Mi Sphere, I recommend MiSphere Converter, an app that was previously available only for Android but is now on iOS.

Xiaomi Mi Sphere (reviewed here) is one of the best 360 cameras for photos and virtual tours, and already has good stitching thanks to its very thin profile which minimizes parallax stitching error. Mi Sphere Converter is a 3rd party app that improves the stitching quality even further in several ways:
1. Optical flow stitching
2. Correct color difference between two lenses.
3. Automatic horizon leveling. You can also fine-tune the horizon level.
To use MiSphere Converter, you need to transfer the unstitched photos from the camera to your phone. There are several ways to do this (see the Mi Sphere FAQ). After the unstitched photos are in your phone, select them and “share” them to Mi Sphere Converter. This will open the photos in Mi Sphere Converter. From there you can calibrate the stitching (you need to do that only once for a camera), adjust the horizon, or choose how photos will be stitched.
You can get MiSphere Converter from iTunes or from the Google Play Store.
I’ve been waiting for this for a long time…One problem though…How exactly do you import the unstitched photos to your iOS device to be stitched? The iOS photos app doesn’t recognize any photos to import from the camera when connected by usb cable. The MiSphere app won’t import the unstitched photos either.
Great question Daniel. You can try to use a micro sd card reader with a lightning connector, or upload the files to the cloud and download them to your phone, or use iTunes to transfer files to your phone. Those are some of the ways.
I was looking to avoid having to use any other middle man devices to transfer the files and just came up with a method to not only get the photos without any kind of adapter, but also a way to batch download them! I will email you the steps I took as it would make a great tutorial for iOS users.
There is an excellent explanation on this wikki. https://360rumors.com/ultimate-xiaomi-mijia-mi-sphere-360-camera-faq-wiki-and-resource-page/?fbclid=IwAR2fEq02mXArfAY_4vXlzm5xROXS101Q-4utEc0JOoF7OCzDXQo5cqbEUhs#unstitched
Thanks!
Thanks Mic, didn’t know this was now on iOS!!
Question: does it stitch photos that have been post-processed on the computer? I like to tweak colours / merge bracketed shots etc in photoshop first, will this then accept the files to stitch? If so it will make a great addition to my workflow. Also, does it add in the 360 specific file information, or does that still have to be injected afterwards?
hi Roland. yes i believe it can use edited unstitched photos. The stitched photo will indeed have 360 metadata
Thanks for confirming Mic
Mic, Did you get the email I sent you with the batch download instructions?
If I purchase the app for the iPad does it work for my iPhone also or is another purchase necessary?
it should work for iphone also
You can family share on up to six family members.
I also located this:
I’ve got good news for you: iOS apps that you’ve bought or downloaded from the App Store can be used on every compatible iOS device you own—as long as they all use the same Apple ID, that is.
App purchases are made using your Apple ID (just like when you buy a song or movie or other content). The purchase grants your Apple ID the rights to use that app. So, when you try to install or run that app, the iOS checks to see if the device you’re running it on is logged into the Apple ID used to buy it originally. If it is, everything will work as expected.
Just make sure to log into the same Apple ID on all of your devices, and that the same Apple ID was used to buy all the apps, and you’ll be fine.

Thanks!
The iOS devices don’t need the same Apple ID. They can have different id’s if they are under the Family Share group. Purchased items can de shared.
Thanks!
useless software if no desktop available
Mi Sphere does have a desktop stitcher, capable of batch stitching. It’s now available for both windows and mac 😀
Some of my images come in stitched sideways and others are fine. How do I fix this?
When you say stitched sideways you mean it’s not level? It may help to give the camera a few seconds held upright after powering on to ensure the gyro is stable.
