Chalk Calls

Chalk is a simple way to start or join a video call from your phone. Tap Start a call and share the link, or open a Chalk link to join right away. No account is needed. In a call you can: - talk with clear, low-latency audio and video - switch between Spotlight and Grid, and pin the person you want to see - see who is talking from the ring around their tile - raise your hand or send a quick reaction - chat with everyone and share files - see the People list and who is muted - watch a screen or whiteboard someone else shares - pick your audio output and turn your phone sideways for a bigger view Each person without a camera gets a friendly animated face, so a call never feels like a wall of initials. Chalk comes in Dark and Light, and you choose which one you want. Chalk is open source (MIT), and one engine runs web, iOS and Android.
