SignaI Plus is a messaging app for simple private communication with friends and family forked from OpenWhisperSystems with more advanced options.


★ SignaI Plus uses your phone's data connection (WiFi/2G/3G/4G) to communicate securely using an advanced end-to-end encryption protocol that provides privacy for every message every time. Optionally it supports plain SMS/MMS to function as a unified messaging system, and can also encrypt the stored messages on your phone.

★ Using SignaI Plus, you can securely and privately send / receive Texts, Images, Audio, Video and voice notes along with Contacts, Locations and more to come.You can register using your existing phone number and address book that is NOT uploaded to the server.

★ Make privacy stick: Stickers are now available in the app! You can send stickers in any conversation, add them to pictures using the image editor, and create your own custom sticker packs using Bharat Desktop.

★ SignaI Plus is Free and Open Source, enabling anyone to verify its security by auditing the code and check its peer-reviewed cryptographic protocols.

★ A Fast chat app. The "Signal" protocol is designed to operate in the most constrained environment possible. Using SignaI Plus, messages are instantly delivered to friends.

★ Speak Freely - Make crystal-clear phone calls to people who live across town, or across the ocean, with no long-distance charges.

★ Whisper in the shadows – Switch to the dark theme if you refuse to see the light and (for OLED users) save battery by doing so.

Many more features to come.
