How to download Insta360 player????

I spent several days looking for link to download Player for raw shoots from Insta360x2.

According what i see on the web, at least pictures, this application excist, and even probably excist for MacOS, but there is no any link in official website or plugins for external picture/video viewers.

Also, iphone/ipad app works extremely slow. May be there are some way to optimize it? Thanks
