CallUp

CallUp is a private messenger that keeps you connected across borders. Chat, call, and stay in touch with the people who matter, wherever they are.

PRIVATE BY DESIGN

Every message and call is encrypted on your device and stored encrypted. No ads. No selling your data. Other users cannot read your messages, and CallUp stores your encryption key so your chats are there when you sign in on a new phone.

FREE CALLUP TO CALLUP CHAT AND CALLS

Messaging, voice and video calls between CallUp users are free and unlimited. Get your own CallUp handle and start talking. No phone number needed to begin.

CALL ANY PHONE, ANYWHERE

Reach ordinary phone numbers around the world over the internet, at clear per-minute rates. You see the rate before the call starts and pay only for the minutes you use. Pay securely by card.

TALK ACROSS LANGUAGES

Built-in translation lets you read and send messages in another language, right inside the chat. The original text is always there.

MEET NORA

Nora is your free in-app helper. Ask about CallUp, or have it translate, draft, or look something up. Nora runs on Claude by Anthropic, so what you send to Nora is processed in the cloud to generate a reply. The Nora chat is not private the way your personal chats are.

BUILT FOR WEAK NETWORKS

Designed to keep working when the connection barely does.
