You should WANT to make video calls.
Knock Knock is video calling done right — warm, instant, and out of your way. Sign up with just your phone number. No email, no password, no profile to fill out. Open the app, knock on someone, and you're talking.
WHY KNOCK KNOCK
- Just your number. Verify once and you're in — nothing else to remember.
- Knock to call. Tap a friend and "knock" to reach them, like stopping by their door.
- Calls that hold up. Crisp 1:1 and group video, even on bad wifi.
- Cozy, not cluttered. A warm, calm interface that gets out of the way.
- Share your screen, right from the call.
- Rings natively on your lock screen — answer like any other call.
Calling shouldn't feel like a chore. Knock Knock makes it the easiest, warmest way to actually see the people you care about.
Video calls, finally done right.
