Nextcloud Talk is a free communication platform available on iPhone. Developed by Nextcloud GmbH, it allows users to have one-on-one or group audio or video calls, create or join web conferences, and send chat messages. The highlight of Nextcloud Talk is its emphasis on privacy, as all communication is fully encrypted and mediated by your own server.

Easy to use and completely free, Nextcloud Talk offers a range of features including HD audio/video calls, both group and one-on-one, webinars and public web meetings, individual and group chat, easy screen sharing, and mobile call and chat push notifications. It seamlessly integrates with Nextcloud Files and Nextcloud Groupware, providing a comprehensive communication solution.

Nextcloud Talk is fully on-premise and open source, ensuring complete control over your data. The platform also supports end-to-end encrypted calls and can scale to accommodate millions of users. Additionally, it offers a SIP gate for dialing in by phone.

To use the Nextcloud Talk app, a Nextcloud Talk server is required. Nextcloud itself is a private, self-hosted file sync and communication platform that gives users access to their documents, calendars, contacts, email, and other data. It can be deployed on a server of your choice, providing a secure and customizable solution for businesses and individuals alike.

With millions of users worldwide, Nextcloud is trusted by businesses and homes for its professional support and enterprise-ready platform. It empowers users to take control of their data and collaborate effectively in a secure environment.
