Heartline

What is Heartline?

Long-distance love deserves more than a text bubble. Heartline sends what words can’t.

Press your phone and your partner feels your heartbeat on the other side of the world. No typing, no thinking, no pressure. Just a pulse that says “I’m here.”

Works across timezones with smart scheduling so you never wake someone up at 3am with a vibration.
