Hello!

About Jitis on mobile: the most part of the all available video services which provide video conferencing use their own mobile apps to make the video signal more stable and to work on different devices, because each OS and browser has their own peculiar properties. So, we don't work  on some of them.

About video recorders: Mac and IOS devices didn't support MediaRecorder object in previous versions and just have added this ability. We are working on video recorder and it should be available very soon for IOS and Mac os.
