Seems like an awesome app. Couple of things to improve upon to make it a five star app. This app IS great, but you *must* have an option to stay logged in. Otherwise it removes a large part of the messaging app feel and makes it less appealing for most people. Also, some messages for some reason, just disappear from the chat. Make this more reliable, possibly working without google play services, an option to stay logged in, dark theme. we appreciate everything thus far. Thanks

Absolute trash. Why, you say? I SPENT 3. something HOURS TRYING TO CORRECT MY USER, and when i did, the number wasn't compatible with what i was trying to do. It's good for other people i guess, but for me no. How you can better your app; literally just fix the username problem , 2 HOURS GONE. But yeah, other than that the service it provide is alright.
