About

RollerText 3

News reporters often have to improvise a speech at a disaster or a war zone to give live updates. Some people have to make a live speech in front of a large audience before receiving an award. All these people have in their hands are maybe just a microphone and an iPhone. Instead of resorting to a piece of paper with some information on it that can easily be blown away during a Category 5 tropical storm, can they use their iPhone or iPad at hand instead to read a speech script that they have prepared beforehand? RollerText 3 is an iPhone & iPad app for news reporters and speech makers who sometimes have to improvise a speech in a situation where they can't bring a big machine like an expensive teleprompter.  You won't need this app if you are happy working with a text or PDF file during a speech. RollerText 3 isn't just a simple plain text file reader. It lets you use your device as a virtual teleprompter such that you can see a rolling text script letter by letter on your device screen. And you can control the rolling speed. Double-tapping the screen, you can pause and unpause text rolling. By this approach, you will know what to pay attention to over an entire transcript during a speech. On top of a rolling text feature (Text Rolling), RollerText 3 has three additional text presentation features all packed under one app. And you can switch from one to another with just a finger tap on a drop-down menu. All these four text presentation features require plain text files (.text, .txt) as speech transcript sources. Text Rolling: Roll a text script letter by letter with a speed of your selection. Text Highlighting: Highlight keywords that you want to emphasize with a color of your selection over a text script. Text Flashing: Show a text script line by line, letting the app automatically switch them with a time interval of your selection. Text Switching: Show a text script line by line and switch lines on your own by double-tapping the screen. RollerText 3 comes with an 8-page Quick Guide that explains how to use it. Tap the red question mark button over the toolbar menu at the top to read it. - System requirements - 1. iOS 17.0 or higher 2. iPhone or iPad - Limitations- 1. The user must use text files (.text, .txt) as speech transcript sources that are stored in their device or iCloud Drive. 2. As free trial basis, RollerText 3 lets the user have access to as many as three files in presenting text and also create a maximum of three keywords in highlighting text. Subscribing to one of the four plans available, they can upgrade their use base to 'Unlimited' such that they can have access to an unlimited number of files in presenting text and create as many keywords as necessary in highlighting text. - End User License Agreement - https://blog.mhvt.net/?p=7526#termsofuse
