Description
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.

Recent changes: ★ The media editor has been completely redesigned to better support tablets and foldable devices, and now it looks great on screens of all sizes. ★ The new media editor also supports removing the audio track from a video before you send it. If the pastoral slow-panorama footage from your vacation to Scotland was partially ruined by the sound of wandering sheep, with just one tap your movie can become the silence of the lambs.

Way better than MMS! I love the focus on privacy. Has much better features than regular MMS or even RCS. Messaging is reliable and fast. Photos and videos are better quality. Read receipts, better privacy and encryption are nice. No ads or paid upgrade nagging. Easy backups/restore! The UI could use a little more polish though. Sometimes feels a bit dated for some reason.

The app is great and easy to use but the only thing I have as disconviens is the procedure of funding and cashing out MOB if only you just do a direct purchase using your credit or debit card to fund your MOB and either direct deposit to your bank or strip account aside that everything was perfect 👌

Updating to 5 stars since now signal can work on multiple phones through a single account, plus sent a donation too <3

This is an amazing app, just made my friends switch to this app, instead of using apps from meta (like WhatsApp and Instagram). Privacy is the human right, but it's getting rare each and every day.....

Private app? Seems funny you start off with 1 person to have private chat with then end up with 3-4 people who you haven't even chatted with or don't know? Don't seem to private to me n my family business

Worst support team I've ever been in contact with. Been trying to sign up FOR ONE MONTH but the app KEEPS ON giving me ERRORS saying it can't send sms or call for me to get the verification code. I emailed support, got hit with an automated response followed by just one more email literally repeating what the first mail said as if they didn't bother to read the first email and never reply. What a joke. They asked for my personal information which I literally provided in the first mail.

This app's encryption protocol is weak. Your plaintext keys are readily available on the IS2P Dark web. If you consider this app "secure" you probably shouldn't be using the Internet at all. Here's a hint; if a security app immediately asks for your phone number, it's not interested in your security.
