Session iOS

Download Session on the App Store


Session integrates directly with Loki Service Nodes, which are a set of distributed, decentralized and Sybil resistant nodes. Service Nodes act as servers which store messages offline, and a set of nodes which allow for onion routing functionality obfuscating users' IP addresses. For a full understanding of how Session works, read the Session Whitepaper.
