Ratings and reviews

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.

Its always been a 5 stars, don't write reviews unless there is a problem, the latest Android update messed something up, on reddit many talked about the same problem, no notifications, until you open the app. And for me, i get the notification sound after i open up the chat. The message could've been from 30 minutes ago. Hope this can get adressed soon.

I like this app. It has gotten much better since my earlier review. I don't use the phone call feature, but otherwise, it's becoming my first choice for messaging. still needs a bit of work. Especially if you switch sim cards a lot. The sim card switching has finally improved so it's now an easy full functioning app

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.
