Teleprompter with Video Audio is the best app for anyone who needs to record a speech. With this, you can have a teleprompter on your phone while recording using your back or front camera. You can easily customize the size of the text and the speed of its scrolling as needed. The text also scrolls close to the camera lens so that it will look like you are really talking to your audience.

This app also makes it easy to create presentations. Moreover, it enables you to add your own brand logo and title. It supports multiple file types, so whether your script is in PDF, TXT, or DOCX, you can import them into the app.
