WhatsApp, LINE and even Telegram might have more users, but they are not as safe as this app. It’s a messaging app with features like one-to-one messages, groups, stickers, photos, file transfers, voice calls, and even video calls. Signal is a secure and private instant messaging client that provides an additional layer of safety that other similar apps just don't have. Not even Signal's servers have access to the information of your groups.Īs you'd expect, Signal lets you send all kinds of files, including pictures, videos, and audio, always protecting them with the same protocol it uses for text messages. Whether you're talking directly to an individual or a group, all your messages are always kept absolutely private. The app uses end-to-end encryption, protecting every message you send to your contacts. There's no independent login, no username or password – the app uses your phone number and your address book, so in theory, you can't pretend to be someone you're not.

The app aims to guarantee safe and completely private communication between its users.Īs soon as you start Signal for the first time, you'll notice its security features.
