A Prompter for Android is a free prompter app developed by MonacoDevDroid. It is designed to be used on tablet-sized devices and offers features like mirror mode, full-screen mode, and the ability to read plain text files (.txt only). The app also allows you to edit text directly in the prompter or copy/paste text from other applications.

However, it should be noted that some professional functionalities are paid options. The app also offers a remote control (Bluetooth) option, but this is also a paid feature, and two devices may be required. The app warns that if you choose two different screen-sized devices, the displayed text may not be the same, and the slave device must synchronize with the master.

It is important to mention that the developer has announced that this app is no longer in development and that paid professional options are no longer available for purchase. The developer recommends users to try "ApdfPrompter" for a better and more powerful prompter that is also able to use text files, PDFs, or Google Docs files.
