Signal Private Messenger

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 attachments all with complete privacy. The server never has access to any of your communication and never stores any of your data.


★ Say Anything. Signal uses an advanced end to end encryption protocol that provides privacy for every message 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 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!

To early to tell, but so far it's been working ok. All though a few times it has interfered with my Bluetooth pairing with my vehicle & also caused a freeze up to my phone having to reboot the phone. Other than that it seems to be pretty secure. And just now answering your questions at the bottom of this page, I don't see the area to submit? Oh look it just popped up, strange?🤔

I really like this app and I use it for SMS messages as well. However, it doesn't work well with my vehicle (Bluetooth paired) as I don't get the new messages alert on my vehicle unless I have the vehicle audio system set to the Bluetooth audio input. Also, when people call me using their Signal and I'm in my vehicle, my vehicle alerts me but it doesn't show the caller ID info. Instead, it shows me that my own phone is calling me and I have an option to put it on hold.

Love the interface and the privacy. My only problem with this app is many times it takes a long time to deliver messages. I'd be talking to my friend and send a message and it would get stuck on one checkmark for a minute or two. I know it's not my internet connection cause all other messaging apps run fine and my internet is usually between 100-200 Mbps. Hope you guys can fix this cause that's my only gripe with Signal.

Dy. E. May 21, 2022     

We've used this for over a year. In addition to knowing our communication is secure, I like the confirmation that a message is delivered/read. It's pretty seamless even with non-signal users. The accompanying desktop app is great! There are a few oddities: when the safety number for a contact is reset it's a little clunky if you aren't local to one another.

Just amazing, recommending it to everyone these days. Open source makes it trustworthy and I know it will keep on improving! Edit: unfortunately they dropped sending uncompressed images, which was great for exchanging your shots with someone without loss. Also can't send vids bigger than 100MB, apparently compression can't handle that. Cross-platform reliability has got really good tho!

Very difficult to send images, not at all an intuitive or fast interface. Also produces an annoying and unhelpful warning message whenever you try to save images. You can't send videos at all. Good for important stuff, but for casual conversation, it loses a lot. Since my phone requires a "default" app for texting people, I end up using it for both. Needs some UE improvement, but functionally it's fantastic.

Seems good enough. Good reputation. I seem to occasionally have a hiccup when someone doesnt get a message but then maybe they just arent picking up. I'm having some issues with the timeliness of some texts. It seems that sometimes I don't get prompt texts when I'm trying to figure out when someone is ready for me to pick them up. Some of those texts don't show up until much later than I need. Sometimes not until the following day.

Had to reset my phone so I tried to restore a backup, but it failed and now I've lost 3 years and 2.1 gigs of data :( I still have the backup file but can't do anything with it. I think it's because the version of Signal that generated the backup wasn't the same that was reinstalled, but there was no warning on the app. Would love a solution to this.

Been using since March 2022 and so far it's been an easy, intuitive, safe way to communicate free of any noticable issues. As an Apple-to-Android convert a few years ago, I really appreciate having a messaging app again where I can react to specific text boxes. Phone calls have been exceptionally crisp sounding; texts are sent/received instantly (often message my partner in the next room and can hear the ding immediately). Overall I'm a fan!

Eli. P. K. May 5, 2022     

Best messaging app (and I've tried many). Also great for making crystal clear calls. Great for sharing photos etc. One feature I love is how we can customize each conversation with a special wallpaper and color. This kind of personalization makes it FUN! Other features I love are disappearing messages, the privacy, the "note to self" feature, ability to send voice messages.

Tom. F. May 21, 2022     

Works very well. Audio calls are good quality. Any more WhatsApp constantly drops calls and is very unreliable for that. I also like the feature of being able to delete messages after a certain time period so it does not keep eating storage space on my device.

Rag. B. May 23, 2022     

For being a nonprofit, they run a solid app. A few features could be added (like the ability to add a caption next to each photo) but overall works great. Voice calls are clear, and 100+ member groups also function smoothly. In fact WhatsApp copied a few of its features, like the ability to emoji-react to a message.

Aoi. G. Apr 30, 2022     

My only complaint is I wish I could receive/send my normal text messages on the desktop app as well. Maybe you can do some kind of proxying thing through the app on the phone. You know Google's messaging app has a web interface option that lets you send and receive SMS from the desktop. I'm not saying you have to do it that way but I am saying add normal SMS text messaging to the desktop app please!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Var. N. May 19, 2022     

Suggestion: it would be really useful if you could just select multiple files and send them all at once! Don't sell it out... hope the developers get enough contributions to keep it going. I wish it wouldn't put deadlines on updates. ***When will people make apps so they don't demand updates?*** Let them keep working even if functionality is limited. Glad to have it going again, and the recent upgrades haven't been harmful at least. Keep up the good work!

Rya. C. Apr 23, 2022     

It's an excellent application. The only little annoyance I can think of is the inability to select and delete multiple chats at the same time with a touch-hold gesture. It was present in a previous version if I remember correctly. Otherwise it's a really well made app. It's fast, smooth and works very well. Definitely worth a download If you value privacy whilst messaging on your smartphone.

Ant. S. Mar 9, 2022     

Works great! I do have a problem where when I call someone and I'm using any Bluetooth device, they won't be able to hear me but I can hear them. Hanging up and making a second call always clears up the issue though. Voice calls come through clear whether I'm on WiFi or cellular however they don't transition. If I switch networks, I need to hang up and call again which usually isn't an issue. Definitely my go-to app for chat and voice. Good solution for the privacy minded individual.

Gra. M. Mar 17, 2022     

Great app! However I think it's lacking in privacy for not having the ability to choose who can see your phone number in group chats. Telegram has the ability for a user to choose to change who can see their phone number to only people in their contacts or to no one. Signal should get that feature as well for more privacy and then it'd be perfect.

Ama. B. Apr 19, 2022     

The messaging app is great and I appreciate the privacy. There are just a few things the need to tidy up. For instance, when you're on a video call and there's a network fail, the video cuts but the audio remains. The only way to regain video connection is by ending the call and redialing. For some reason, sometimes the call doesn't go through and all you get is a missed call message in the chat and sometimes a notification.

Joe. M. Mar 5, 2022     

This is the best and most functional messaging app I've ever used. I used Next SMS prior to using this app, but I won't be going back to that one after learning about this. I love how the messages deletion can be adjusted. I'm able to have video calls to my friends who use iPhone from my Android. I no longer have to wonder if my messages have been received, read, and I can see when the other person is typing. Only feedback is to add the ability to schedule messages. Great job developers!

Car. F. Mar 22, 2022     

The notifications are more reliable than another messaging app that was bundled with this smartphone, so bonus points for that. The video portion seems to be a bit sensitive to the quality of each participants wifi signal, so the image sharpness will shift around between the participants on my screen. There is occasional freezing and dropping of videos in calls, but less so than some other video call apps. Overall a good product.

Sud. Mar 12, 2022     

So far my experience with this app has been good. However, I do have to provide feedback regarding restoration of screen during a video call. The issue that I faced multiple times is when I'm on a video call and the WiFi cuts out and is restored, I don't see myself on the small screen and the screen is frozen saying "network fail" but the person I'm talking to can see me and hear me. This is the only issue I face with Signal.

Edit: They should really request for battery optimization to be disabled on install. It's great. There is a difference knowing that you're having a private conversation. Negatives are that group calls seem to have not that reliable connections (at least on desktop), a friend of mine got spam messages threatening him when he first signed up (and I also read about it happening to other people), and they don't have the thumbs up button or reactions like on facebook (it really makes a difference).

Sag. B. Apr 9, 2022     

Worst thing is when I'm on call connected to Wi-Fi, after a while, the Wi-Fi disconnects and connects via mobile data. I have to manually toggle the Wi-Fi on my phone to connect. The voice breaks a lot on this app and not when I use any other app. When I call and turn off screen before they answer, they cannot hear me. Other than that, Simple and clean interface. No clutter or fancy stuff. No story or status nonsense. Just chat and calls.

Ste. D. Apr 24, 2022     

Mostly great. But it's having trouble attaching some photos. They show as black thumbnails in the selection screen, and fail to send if you try. If "note to self" then it still fails, but different (get endless spinny wheel). Seems to be only heic files, but not sure. Seems to be larger file sizes, but there are counter-examples. Maybe related to the size they inflate to as jpeg?

Eli. I. Mar 20, 2022     

Lost 2 stars for a lot of trouble with delayed messages on this app with the secured messages. Sometimes I will be on my data connection looking at websites & using other online apps (indicating the connection is good) and the progress indicator will show the circle indicating that the messages have not gone through. I never know if the delay will be minutes or hours. For secure messages on the data, I just set it going and wait. Many times it only sends when I reach Wifi.

Dar. T. Apr 5, 2022     

Overall, the app works well but there are two extremely frustrating issues: 1) Opening a folder to attach a file takes an eternity. Even with internal storage (no SD card), it takes longer than necessary. 2) The bombardment of notification sounds while a message is unread until opened as well as while you're in a message string and receive a new message. In either situation a silent or more muted effect would be preferable. Funnily enough, Whatsapp doesn't have these issues...

Col. H. Mar 30, 2022     

It really is a nice app. The only problem I have is that though I have set up the notification but it never sounds. Finally, there seems to be a time delay. So if you want to check for messages you have to go into the app, the person you checking on for messages: you have to wait for 2-3 seconds before the message appears, that was sent hrs ago.
