A light for the people you miss

A mother in another country, a son across the ocean, an old friend in another city. Karot keeps a small light on between you — no feed, no counters, nothing to keep up with.

• Think of someone, and their light glows. One tap. They see that you thought of them, and when — never how many times.
• Letters that arrive on a day you choose. Written or spoken, sealed until the morning they land.
• A widget on the home screen. Their light, and a tap back, without opening anything.
