I use an app called Tiny Planet maker. Only small, and easy to use. I haven't found an alternative way to export the pictures as tiny planets, but this app prices ok
Here's a pano I shot yesterday: Kuula | Share 360/VR photos and build virtual tours! I used DJI Media Maker to create the master image. Then used Photoshop to increase the canvas to a 2:1 ratio and added the sky. I realise that the images created by media maker are no good for spherical views as they are the wrong aspect ratio and there's not enough sky.
