Working with panoramas in iOS and Android?

Question

Android

Good day to all.
There was a need to develop an application in which there will be 360 ​​panoramas of the halls. Hotspot support is also required. All this is being developed for both iOS and Android. Actually, the question arose: are there any suitable solutions for both platforms? Interested in both free and paid. As already mentioned, support for hotspots and high resolution with the ability to zoom is required.
So far I have found only PanoramaGL (opensource), everything is fine, but it only works with low-resolution panoramas - as a result, it does not look good on tablets.
Thanks in advance!

By the way, I settled on krpano - a great tool. Maybe someday I'll make a post.
