What's New in Chalk

• Chalk draws while it explains. If it says it will put something on the board, it puts it there. • Hold to talk: one button. Hold it to speak, let go to send. • The board is the whole screen now, and keeps making room below as you work. • Each board keeps its own conversation, so a new board starts fresh. • Fixes a case where the tutor could not see work you had just drawn. • Fixes math losing a piece of its notation, and circles landing beside the term they meant. • Fixes alerts and confirmations that were not appearing.
