Google Talkback is very useful to get information about what’s going on your screen. The concept of this app is very good. It reads out the actions that are happening in the screen of phone. It speaks everything that is happening on phone screen. It provides spoken response to the user about the action. I’ve used this app and it works very well. The main feature of this app is to give spoken response to the user. The app is very useful for low eyesight people.
