MolaSync is an innovative tool for collaborating and recording. This app has realtime collaboration/ recording/ sharing/ communication/ drawing features.
With MolaSync specially designed for iPad, You can draw and record your inspiration at anytime, anywhere, insert pictures and words and even record to write notes and annotate to modify PDF documents. More exciting, with the collaboration function, your students can exchange views and work together with their friends. Together, complete a drawing, a document, a design, a class project, and share their achievements or show them via social network. All the content created in MolaSync will sync to the cloud and ensure that files are up-to-date on all your devices. The local cache enables you use your MolaSync without a network. Powerful vector graphics make this app something special.  MolaSync significantly expands the value of the iPad in the classroom. As of today, this app is now free. I’m not sure if this is for a limited time.
