Signal

Signal is a social communication software that places great emphasis on user privacy and security. Users can create or join groups of hundreds of people at any time, freely sending text, voice, photos, and videos in various formats to exchange and share wonderful moments and interesting topics, thus making like-minded friends. The software uses end-to-end encryption technology to protect users' chat history and account security at all times, and does not collect user data, ensuring users can use it with peace of mind. The software is also continuously updated and optimized, launching more interesting social tools and improving encryption technology, so users can look forward to it!

Features of Signal:

Privacy by default: Signal applies end to end encryption to every message and call. The service cannot read your messages or listen to your calls, and it collects minimal metadata. There are no ads or trackers. The Signal Protocol and app code are open source for public review.

Rich messaging over data: You can send texts, voice notes, photos, videos, GIFs, stickers, and files using your data connection. This helps avoid SMS or MMS fees from your carrier. Conversations continue whether you are on mobile data or Wi Fi.

Clear, encrypted calls: When a call is better, Signal offers encrypted voice and video calls with clear audio and stable video. You can also start secure group calls with up to 50 people. Calls work across countries and networks.

Groups that scale: For larger conversations, Signal supports group chats with up to 1,000 members. Admin tools help manage membership and control who can post. This setup works for families, clubs, classrooms, and communities.

Privacy controls you choose: Beyond encryption, you can set disappearing messages to remove chat history on a schedule. Usernames let you connect without sharing your phone number. Encrypted stickers and notification privacy options add control over what appears on your screen. You can also share image, text, and video Stories that expire after 24 hours and set who can view each Story.

Highlights of Signal:

Comprehensive Security for Modern Users: Signal Private Messenger, developed by the Signal Foundation, provides a robust solution for individuals seeking privacy-first messaging and calling. Utilizing advanced end-to-end encryption by default, the app ensures that messages, calls, media, and group conversations remain accessible only to their intended recipients. All cryptographic processes occur on the user's device, preventing even Signal itself from viewing message content or metadata.

Wide Range of Communication Features: Signal offers more than just secure messaging. Users can exchange one-on-one and group messages, initiate high-quality voice and video calls, and share photos, videos, and documents. The platform supports quick sending even over slower connections, which is especially advantageous for users in areas with limited internet speeds. Signal also includes a voice note feature for added flexibility in communication.

User-Friendly Design and Customization: The interface is clean, intuitive, and well-organized, presenting recent chats prominently, with easy access to both camera functions and chat creation. Profile setup is straightforward, requiring a phone number and a brief registration that includes PIN creation for enhanced account protection. Users have control over app appearance, with adjustable themes, including a Dark Mode for nighttime use.Custom notifications allow individuals to tailor their experience per conversation, reducing distractions. Additionally, Signal integrates a built-in photo editor, so images can be quickly cropped, annotated, or blurred before sharing—a beneficial touch for privacy-focused users.

User Reviews of Signal:

Though Im not a technical expert and cannot comment on its security, from a user perspective, it is a well-equipped and highly customizable messaging app. Day to day use is largely smooty, though sending larger files might be slow at times (which may be due to network rather than the app). Overall a good app and from what others say, the most secure one too!

It's encrypted end-to-end by default. It's free (made by a nonprofit). It's not owned by FB, G, or any other big ad pusher. And it does text, voice, and video. (Missing feature: "Mark as Unread"; I find I often take a quick peek at a message and find that it requires a lengthy reply that I didn't have time to write at the moment, but then forget to come back to it until much later.)

good app, but asked for a rating. I'll let it pass the first time but it's minus 1 star each time after that. things to know: -it requires a phone number to make an account. -signal is a not-for-profit entity or some kind, they will remind you repeatedly. -you can't find groups, only be invited to them via a link. I have not found a site with public groups. -it is secure enough for most normal people -changing or adding a device will cause some extra steps or confusion for your friends.

Realized I can create more than one group chat for diffent types of lists and notes: gratitude list, prayer journal, texting God—and now I can pin messages? I love it. I do hope the text color can be further customized to simply white (background) and black (text/words). I'm visually impaired so it's hard to read the white words on a dark text bubble background when I send the texts.

FAQs of Signal:

Concerned about who can see or message you on Signal?

Adjust your privacy settings to see who can discover you by managing phone number privacy settings.

Reminder: People can still contact you by username if you choose to set one.

Adjust your privacy settings to disable delivery receipts for non-contacts or people with whom you have not shared your profile with. You will still be able to receive messages from them, but they cannot see that you've received the message until you share your profile by accepting a message request. On your phone, open Signal, Settings (profile icon), Privacy, Advanced, disable sealed sender’s “allow from anyone” option.

Block numbers, usernames or groups. 

Note: If someone can see your number at the time you blocked them, they will still be able to see it even if they cannot send you a message in Signal. You can remedy this by changing your phone number privacy settings before blocking them. Then changing them back, if you want.
