Seeking Teleprompter Recommendation

We're looking for a teleprompter app for an Android phone, an app that allows the user to record and save what is being read on the teleprompter, for which the font size of the uploaded script can be adjusted. In other words, as you read your script scrolling by, you can record yourself as if the script was not there and save the recording. Free would be ideal but if there's a reasonable fee, that would be OK, too. Recommendations appreciated, thank you!
