Even though we have Slack huddles, Zoom meetings, Google hangouts, and more available. We prefer Tuple to the rest. It's the best app for screen sharing (and obviously for pairing).
Their support staff are also really good. They get back to you quickly with actual help from caring people.
The app has improved impressively since I first started using it. There are tons of useful features that devs will love. My top favorites are:
1) Scriptable lifecycle triggers. I use this to pause Spotify when joining a call.
2) Hiding certain apps content from being shared (messengers, pw managers, etc.)
3) They give a lot of control to viewers of a screen share. What resolution is streamed, what keyboard buttons I want to send when controlling, drawing, emoting, typing, etc. All make for a seamless experience.
Give it a try !
Sad it came at the cost of dropping Linux compatibility.
