Signal’s advanced privacy-preserving technology is always enabled, so you can focus on sharing the moments that matter with the people that matter to you.

Is Signal secure?

Signal is the gold standard for private messaging apps at the moment. It is free and open source. By using end-to-end encryption as standard, Signal keeps all forms of communication on the platform as secure as they can be. These include one-to-one chat, voice and video calls, as well as group chats.

Is Signal better than WhatsApp?

While Signal and WhatsApp are similar in that they are both messaging platforms, they are built to serve two different purposes.

Signal is open source and collects less user data, while WhatsApp intentionally links user information to your account. WhatsApp offers cloud backup of your conversations, while Signal only stores message history locally, meaning chats will be lost if you lose your phone. This is all done by design as Signal is meant to be more private.

Both WhatsApp and Signal offer end-to-end encryption, for both messages and calls. Both apps require a mobile phone number to access the service, and both allow you to use just one phone and five other devices.

Can Signal make video calls?

Yes, Signal can make video calls to individuals and group calls for up to 40 participants.

Functions

• Imagine this – Use the built-in image editing features to outline, crop and flip your output images. There’s even a text tool so you can add more words to the 1,000 your photo is already worth.

Note: To use the Signal desktop app, Signal must first be installed on your phone.
