Privacy is possible. Signal makes it easy.

Using Signal, you can communicate instantly while avoiding SMS fees, create groups so that you can chat in real time with all your friends at once, and share media or other files all with complete privacy. Signal's servers never have access to any of your communication and never store any of your data.

★ Say Anything. Signal uses an advanced end-to-end encryption protocol to keep your conversations private. Every message, every call, every time.

★ Open Source. Signal is Free and Open Source, enabling anyone to verify its security by auditing the code. Signal is the only private messenger that uses open source peer-reviewed cryptographic protocols to keep your messages and calls safe.

★ Be Yourself - Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose.

★ Group Chat. Signal allows you to create encrypted groups so you can have private conversations with all your friends at once. Not only are the messages encrypted, but the Signal server never has access to any group metadata such as the membership list, group title, or group icon.

★ Fast. The Signal protocol is designed to operate in the most constrained environment possible. Using Signal, messages are instantly delivered to friends.

★ Speak Freely - Make crystal-clear phone calls to people who live across town, or across the ocean, with no long-distance charges. 

Signal is not currently compatible with tablets, but support for larger screens is on our roadmap and will be included in a future release!

Reviews From google play store

Good start for a communications application for the digital age of privacy. I've found a few key features lacking based on current available technology, especially with it's companion desktop client. Some more thought/work should go into making it more solid all round. Is there a list of upcoming features listed on Github or anywhere esle?

Coming from google messenger and textra, this is a very good sweet spot. It let's you customize each conversations color and notification tone. But the biggest thing is the privacy aspect. There is a desktop app, but it doesn't sync the conversation. Regardless, it's great that it's all free and gives me the slight peace of mind.

Signal is one of the most easiest apps to use. The only problem i have exprienced is that i can not get to change my notification sound even though i have tried numerous. Can someone help if they know how to please. Overall i would recommend this app to anyone.

Works well, sometimes crashes when browsing gifs, and I don't always get notifications. Galaxy S7 running Android Oreo. 4/16/19 Ok, hit and miss notifications is getting old, hard to keep using. My wife and kids having same problems. Really hope this gets fixed, missed some important messages. Thanks

Free, open source, easy to use, and can't be intercepted. Call quality is great. Bugs: 1. Some people still get late notifications of Signal msgs, 2. I replied to friend's first Signal msg via SMS, but then I could no longer reply via Signal (despite visible safety number) - I had to reinstall to fix, 3. "Share to" dialog bug where back arrow is unresponsive. Also you can't: 1. See the length of calls, 2. Mark msgs as unread, 3. See which network an SMS was sent to until you've had SMS from both

I am really enjoying communicating on this app. I have felt uncomfortable for years about how my words are collected for advertising purposes or any other purpose. I wonder if a joke I say or a personal struggle I have could get taken out of context and used against me in a terrible way. With this app, I feel more like I am entrusting my words to the person I am communicating with instead of a large corporation that does not respect me or anyone else.

i was really enjoying this messenger, i even use it as my standart sms app. After an update, i can't see anymore, who of my contacts is using signal. I'm a little bit disapointed right now. this means minus one star :(. EDIT: the desktop apps updates once a week and needs a long time to load. quite anoying. minus an additional star

works pretty good besides this one big problem, and I've noticed it from my line and from the other persons line. is when you are talking to someone and you get Another call from anyother platform, the person you thought you just put on hold to answer the other call- that person can hear your entire conversation from you And the other person. Thats messed up! please fix this problem

As a cyber security and hacking consultant, I recommend using this app to secure messages and calls. Signal allows me to flirt with my spouse without informing corporations, governments, or criminals. Just remember that if your phone is hacked, using a secure messaging app will not protect you.

overall goid app. i chose it because of the strong encryption. but for the past 3 months I've had trouble gerting kicked off & having my messages disappear randomly, especially when i tried to i stall the desktop version.

Integration with desktop is not optimal (slow). Guess that's the price you have to pay for advanced security. Also the backup of messages is very clunky. You have to manually trigger it. You can only restore backups when reinstalling.

I use signal on my phone & desktop, desperately want it to work on my Android tablet. Also, IMHO Signal NEEDS some kind of privacy (password?) protection so that just unlocking my phone or desktop doesn't give total access to my otherwise private Signal messages. Since Windows doesn't by default encrypt data this is a REAL problem with Signal Desktop. 5 Stars if they fix this 😁

I have encouraged others to use this app, and some of them have experienced a problem where sometimes they don't receive messages until later and when they finally get all the messages they will be out of order but have the correct time stamps. It seems simple to order them correctly. They've also had a problem were messages won't send at all in a group message. We've been working around this by creating a new group.

The only messenger I trust. While other messengers use the Signal protocol, only Signal is developed by a not for profit devoted to privacy. Other messengers may not read your messages, but what about the trust you give them in accessing your contacts, for instance? Functionally, Signal works well and is constantly improving. it also has less of the unnecessary fluff that you see in messengers. It does private messaging, and it does it well.

it is a good. however, it does noy sound on my Moto G when someone else messeges and calls me. Please help. I already restart the phone, activated Safe Mode, went to settings of both phone and app and could not be fixed.

Nice to finally not have to hold the recorder button anymore, and I like the subtle hint with the lock icon, though I do wonder why swipe instead of just tap, to avoid accidentally starting a recording? Also, fair is fair (though late, sorry), you brought dark grey and some better colours, so you got that star back ;)

When Edward Snowden recomended this app, I was all in. Until about 2 months later when MMS stopped working. Can't send to multiple contacts, nor can I respond if there is more than on person listed. Can *sometimes* see pictures, but can't send them. I tried messaging Signal for support. Got ZERO response.This issue also seems to be a known and longstanding issue. - Sure it's great if you can get all the elements to work. but wo/ MMS capabilities, it's of extremely limited usefulness.

I leave four stars for now one reason. Contacts are not functioning, syncing properly to dell laptop, desktop. Sent bug report(s). "Thanks" for the work on this project. Overall, i think a work very well done.

Changed from a 5 star to 3 star review because of occasional server outages, slow delivery of messages, typing Indicators don't work and support doesn't reply to emails. Need ability to delete messages for all like Whatsapp and Viber. Probably 2.5 stars rather than 3 but to give it a 2 is unfair.

Hate that this app aggressively corrects my writing and spelling especially foreign language words. give me an option to opt out of all corrections. I am choosing this app because NYTimes used it or uses it due to end to end encryption.
