About this app

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, stickers, 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 40 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.

The most secure option to replace other more well established apps. BUT: The daily backups are VERY large and take FAR too long to upload to a cloud drive. An integrated incremental cloud feature would be nice!! It has happened many times that the app doesn't open and I need to restore it, this way LOSING 1 day's of data!!! This should NEVER happen!! At least there should be a desktop app syncing of messages (or merging backups between mobile and desktop app!!) 🤷

Absolutely phenomenal messaging app. It's secure, it's safe, and it's very customizable. You can even change the app icon to look like a weather app or something similar if you need to try and keep this hidden! I highly, highly recommend Signal if you're looking for a messaging app alternative and value your privacy and security.

Good but limited. I have older family who would like the option to receive more notifications such as a push notification when contacts post stories. I'm getting them to switch to this and off of Meta, but it's real quiet out there. They don't think to check the app for stories, so I have to share to our group chat, making the stories feature pretty useless for me. I'm looking forward to more features and options that will make it a viable competitor to other socials for small groups.

What's new


★ The new and slightly refreshed Signal logo can help you digitally experience the feeling of seeing a good friend right after they get a haircut (but it's not a completely new hairstyle).
★ Chat folders let you organize your organizations, group your groups, and individualize your individuals into unique folders that are easy to customize and rearrange.
