The Founder edition is a limited‑run version created to mark the very first prototype and launch of the KaroPal brand. It features a sleek black take on the Green Tree Frog Charm, while the Standard edition uses the classic green color and regular packaging.

The KaroPal Starter Kit includes two devices—everything you need to form your first Circle and start sending interactions back and forth. An Addon unit is a single KaroPal device that lets you expand your existing Circle by adding one more person or connection.

Yes. You can add or remove KaroPal devices from your Circle at any time. This makes it easy to expand from a couple to a family, or to include additional partners, close friends, or long‑distance loved ones.

KaroPal’s technology is built for long‑term scalability, with firmware updates delivered over time so your existing hardware can improve. The themed top Charm is replaceable, and each Charm can include its own sound pack, so you’ll be able to swap Charms, sounds, and sequences as new designs and models are released.
