Signal

Signal is a social messaging app with robust encryption features designed to ensure user data security, allowing users to chat freely with family and friends. The app offers default privacy protection, ensuring encrypted calls and messages without any user intervention. It also features cross-border connectivity, ensuring uninterrupted conversations even when you're in different locations with friends. High-quality voice calls and a user-friendly interface provide a superior user experience.

Features:

Privacy by default

Signal applies end-to-end encryption to every message and call without extra steps from you. It is designed to collect minimal metadata, includes no back doors, and does not show ads or include trackers. The protocol is open source, so its protections are available for public review. This approach reduces what can be learned about your activity while keeping the experience direct and focused on communication.

Rich messaging over data

You can send texts, voice notes, photos, videos, GIFs, stickers, and files using Wi Fi or mobile data. Messages and calls work across borders, so you can stay in touch when traveling or communicating internationally. When access is restricted, optional proxy support can help you connect, subject to local rules. This keeps conversations moving even when network conditions change.

Secure voice and video calls

Signal supports encrypted voice and video calling with clear audio and stable video on supported connections. One-to-one calls are easy to start from any chat. You can also host private group calls with up to 50 participants, which helps teams, families, or classes coordinate without switching services.

Groups that scale

You can manage group chats with up to 1,000 members, which suits busy clubs, community projects, and large work streams. Admin tools help control who can post and who can join, so conversations remain organized. As membership grows, you can assign additional admins and set posting permissions to reduce noise.

Extra privacy controls

Signal includes disappearing messages that remove content after a timer you choose. Stories last 24 hours and offer audience controls, so you decide who can view updates. Usernames let you chat without sharing your phone number, which adds a layer of privacy when meeting new contacts. Notification options allow you to hide message previews or sender names on your lock screen.

Highlights:

Advanced message protection

Signal also uses an end-to-end encryption protocol that protects any message you send to any of your contacts. When in a private chat or group conversation, all messages will be completely private. What's more, just as with Telegram, not even the tool's own servers will have access to the information you share.

Attach other files to your conversations

As we have come to expect, Signal allows you to send all kinds of files in your conversations. Simply select photos, videos, documents or audio files to share them with your contacts from the chat window. All your files will be protected under the same protocol as text messages.

Video calling through Signal is now possible

Signal also offers you the chance to communicate with your contacts through video calls. With HD video quality, a good Internet connection is all you need to chat with anyone via your smartphone's camera.
