Know your people
are okay.

A simple check-in that gives you peace of mind. See at a glance that the people you care about are active and well.

Your bubble

Your inner circle,
visualized.

Keep track of everyone who matters on an intuitive radar. The closer a person moves toward the red center, the more likely follow-up is needed.

One-Tap Check-In

Effortless. Just tap.

No messages to write, no calls to make. A single tap tells your bubble you're doing fine. It takes less than a second — but means the world.

Bubbles

Organize by groups
you trust.

Create separate bubbles for family, close friends, or neighbors. Everyone in a bubble can see each other's check-in status — private, simple, and reassuring.
