Signal is a messaging app with privacy at its core. It is free and easy to use, with strong end-to-end encryption that keeps your communication completely private.
• Send texts, voice messages, photos, videos, GIFs, and files for free. Signal uses your phone’s data connection, so you avoid SMS and MMS fees.
• Call your friends with crystal-clear encrypted voice and video calls. Group calls supported for up to 50 people.
• Stay connected with group chats up to 1,000 people. Control who can post and manage group members with admin permission settings.
• Share image, text, and video Stories that disappear after 24 hours. Privacy settings keep you in charge of exactly who can see each Story.
• Signal is built for your privacy. We know nothing about you or who you’re talking to. Our open source Signal Protocol means that we can’t read your messages or listen to your calls. Neither can anyone else. No back doors, no data collection, no compromises.
• Signal is independent and not for profit; a different kind of tech from a different kind of organization. As a 501c3 nonprofit we are supported by your donations, not by advertisers or investors.

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
Clean. It just works without the fluff. I use it for calls, texts, voice notes, the occasional gif & most importantly the note to self chat to jot down stuff quickly. Love that it now has cloud storage recovery (only for text if you're not paying) besides local backups in case I lose my phone or damage it. It's just a shame that most people aren't on here as I prefer it to M£TAs alternatives. On rare occasions, texts or notifications are a bit delayed by a few seconds but that's nitpicking.

Love signal! however I've noticed a bug to PLEASE FIX♥️: the calls do NOT ring, even with notifications on in the app, and in settings, and the phone in full ring mode. it's very frustrating because I keep missing calls. DEVELOPERS, PLEASE FIX AND I'LL BE VERY VERY GRATEFUL. i use it for a lot of my messaging and it's easy to back up messages.

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.

What’s new
Now you can optionally register for Signal without a phone number. Phone-numberless registration requires a small one-time fee to help prevent spam, but this in-app purchase is never directly associated with the new Signal account. We sincerely appreciate your help beta testing this new feature!
