Other programs have jumped on board with 360 VR support, including Adobe Premiere, Apple Final Cut Pro X, and Magix Movie Edit Pro. Support varies, with some apps including 360-compatible titles, stabilization, and motion tracking. PowerDirector is notable for including those last two. Final Cut offers a useful tool that removes the camera and tripod from the image, often an issue with 360-degree footage.
Skype is one of the most popular video chat apps for any platform. It has native apps on most platforms, including PC, which makes it one of the best cross-platform options out there. The Android app certainly isn't perfect, but it can usually get the job done. You can do group video calls with up to 25 people. The app also features a free text chat, Microsoft and Facebook account integration, and you can even call regular cell phones for a nominal fee. The app still needs work, but it's definitely better than it was a year or two ago. The cross-platform support is top notch as well.
Signal Private Messenger is one of the most popular privacy chat apps. It features end-to-end encryption for all messages, voice calls, and video chats between two Signal users. It focuses a lot on individual chats. There are group chat features, but it's mostly for personal use. This is one of the biggest differences between it and rival privacy chat app Telegram. Video calls worked fine in our testing so we have no trouble recommending them. It's a neat way to get some encrypted chats as well. The app is also completely free and open source. You can't really go wrong with it, but there are better video chat apps if you need group video chats.
