Only 1 important options . 1- You are not allow to send videos Otherwise it's a very good app. When you come back sometime takes time to show the test, looks like it's loading, but sometimes I have to gets out and gets back in or log's me out and I have to setup everything again. And notifications are not on time, you will miss a lot of messages on time.

The app is good except for one thing: if your connection isn't ideal and you try to send a message and it fails to send, the app deletes the message instead of asking if you want to attempt to send again. It's frustrating when you reply to someone but it doesn't send so they go who knows how long before you realize your reply didn't send.

Been using Dust for a while. I like the 24 hour disappearing aspect, and the security. But the old Dust was not particularly visually appealing and had no nice emojis or stickers. The new update is much worse. The high contrast color scheme hurts the eyes, it's unattractive, takes FOREVER to load compared to the older version, and has no emojis or stickers of any kind. I hate the update. If it wasn't for the security features there would be no reason at all to use this app.
