Why Switch to Keo?

FAST: Keo is the fastest messaging app on the market because it uses a distributed infrastructure with data centers positioned around the globe to connect users to the closest possible server.

SECURE: We made it our mission to provide the best security among mass messengers. Keo heavily encrypts all your data with time-tested algorithms.

CLOUD STORAGE: Keo seamlessly syncs across all your devices, so you can always securely access your data. Your message history is stored for free in the Keo cloud. Never lose your data again!

GROUP CHAT & SHARING: With Keo, you can form large group chats of up to 1000 members, quickly share large videos, documents (.doc, .ppt, .zip, etc.), and send an unlimited amount of photos to your friends.

RELIABLE: Built to deliver your messages in the minimum bytes possible, Keo is the most reliable messaging system ever made. It works even on the weakest mobile connections.

PRIVACY: We take your privacy seriously and will never give third parties access to your data.

For those interested in maximum privacy, Keo offers Secret Chats. Secret Chat messages can be programmed to self-destruct automatically from both participating devices. This way you can send all types of disappearing content — messages, photos, videos and even files. Secret Chats use end-to-end encryption to ensure that a message can only be read by its intended recipient.
