I have used 2vr.in in the past after stitching my Lichti 360 degree panoramas.

Sand Harbor South Lake Tahoe - 360° Photo - 2VR.in
I have recently begun using Hangar360 and I must say it takes alot of the stitching and cropping work out of a 360 degree panoramas. It is IOs only at the moment. The only thing I dont like too much is that the top sky area is not filled in with similar looking sky imagery. Its just a big blue circle at the top.
With Lichti at least one can use a photo processing app - i.e. Photoshop and create a faux upper sky.
Hangar360 by default will fly the drone to 300 feet and shoot the panorama very quicky. So quickly in fact that I thought I was going to have some blur or weird artifacts. Not so. The development team has done a great job of whipping the Mavic Pro to the next frame and then snapping quickly.
