About
Signal is a free messaging app built around end-to-end encryption, keeping all communication completely private. Send texts, voice messages, photos, videos, GIFs, and files over your data connection without SMS or MMS fees. Make encrypted voice and video calls with up to 50 people in a group call, or chat in groups up to 1,000 members with admin controls. Share Stories that disappear after 24 hours with granular privacy settings.
