RealtimeBoard 2.0

Web-based whiteboarding & team collaboration tool

RealtimeBoard 2.0 can also be a good fit: simple as Sketch, but collaborative as Google Docs. Check it out here at Product Hunt! I talked to many Designers using this tool and what they really like 😍 is that it's incredibly simple to share and dicuss your work with clients💰 and developers🔧, because boards can be commented and viewed without signup🎉. Although for editing purposes personal account is required.
