Ratings and reviews

Signal is a fantastic messag app (better than WhatsApp). Call quality on this app is the best. Messages are encrypted and seems quite secure compared to other apps. Only down side is backups to cloud services aren't as simple and they take up a lot of space after consecutive backups. It is however easier and faster to upload/move backups to wherever needed. I just wish more people used this app.

This has been my favorite messaging app since 2019, when I started to search for substitution for WhatsApp. Easy to use, secure, and trusted. I'm glad they launched two features, which I missed: schedule message and editing after you have sent your text. They only thing I miss is linking the app to another device. But I guess this is a kind of policy issue in Android

I really like this app and have many good things to say, but since I'm limited to 500 characters, I'll stick to what they should fix. The new version has an animation of a lock unlocking and turning that takes a few seconds before you can actually see your messages. We text because it's quick and convenient and that animation makes texting slower and inconvenient. I'd like to see them get rid of that.

What's new

Chat folders let you organize your organizations, group your groups, and individualize your individuals into unique folders that are easy to customize and rearrange. Set up folders to quickly display unread messages from your favorite people, filter by chat type (1-on-1 and groups), or create separate folders like "Personal" and "Work" so you can clock what's happening right after you clock out.

Try chat folders today in Settings > Chats or simply long-press on any chat in the chat list.
