Ratings and reviews

An awesome app when I first got it. But someone is monkeying around with it and it has become an intermittent pain in the butt with sending and receiving messages for almost two months now. Hey, Devs! Doesn't get more secure than,"no one is getting any messages." Fix your servers and intermediary systems. Love the Edit function but not at the cost of functionality.

I've been using signal for years, but apparently the default is for the chat back up to be disabled, and there is no cloud. I tried to open the app on my tablet, but it signed me out on my phone without warning and without prompting for a sync, which then lost all of my message history. There is no way to get them back because signal doesn't save anything and unless you had the foresight to manually enable your backup, you'll never see those messages or pictures again. Thanks signal. You suck.

It's been great app with a couple of exceptions lately. I especially like that you can edit your messages at any time and send "Notes to self".. I don't know if because of my new phone or because of the app but lately when I try to edit it'll sometimes want to discard my message instead of letting me edit. And then sometimes even when it's letting me edit the message will just disappear. But up until recently, before getting my new phone ( Google pixle 8) the app worked flawlessly.

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.
