I’m a solo creator, I built a simple free tool named "LiveSyncDesk" to fix the annoying "Screenshot → Send → Explain → Repeat" problem on mobile while you explain something which always kills your explanation flow.
Here you can open a shared board and both people see & edit the same thing live in real-time flow.
I’m looking for a few people to try it and tell me honestly — is it smooth or confusing anywhere? I’ll improve based on your feedback.
It's Free, opens directly on browsers, No Signup/Login required.Try it from here:
