A single KaroPal Add-On Unit for expanding a Circle you already use. Add one more screen-free connection point so another person or location can join your everyday check-ins. How it works Each KaroPal has one simple switch that reads three inputs: tap, press, and hold. Send one, and the other devices in your Circle chirp, vibrate, or glow. Use the factory Handshakes, or create sequences with meanings only your Circle knows.

What's in the Box

Starter Kit: two KaroPal devices.
Add-On Unit: one KaroPal device.

Every device comes with an American Green Tree Frog Charm and a USB-C charging port.

Setup and App

Each device needs a one-time setup in the KaroPal phone app, which works with Android and Apple phones. The app is also where you create and manage Handshakes and Circles. Everyday use happens on the device itself, with no screen needed.

How It Works

One switch, three inputs, endless Handshakes. Tap, press, or hold, and the other devices in your Circle respond with a chirp, vibration, or glow. Start a Circle with a Starter Kit and add more people with Add-On Units. Send a signal to one person or to everyone in the Circle. Factory Handshakes and a sound pack are included, and you can create your own Handshakes in the phone app.

Battery and Portability

KaroPal is battery-powered, USB-C rechargeable, and portable, so it can sit on a desk or travel in a bag.
