This app – probably one of the best tools for effective teamwork and sharing –  allows making sketches and notes.

With the help of Live Sketchpad, users can organise a conference call with up to five friends, share the same canvas and use the same set of tools. The app saves all drawings and comments; users can refer back to them, as needed.

Also, the app allows participants to share the drawings with voice notes attached to specific points on the picture when a call is not possible or necessary.

Live Sketchpad’s mobile version helps arrange pictures on mobile devices.
