Application Name: ForPrompt Mobile Software Download Links: iOS: [login to view URL] Android: [login to view URL] General Overview of the Application: The ForPrompt Mobile application is primarily software designed to assist users in tracking speech texts or presentations in an organized and readable manner. Through Bluetooth connectivity, users can control the scrolling direction and speed of the text. These applications are commonly used by YouTubers, news presenters, social media content creators, hosts, speakers, and other media professionals. Features to be Added: 1-Simultaneous Text Scrolling: The software is controlled via Bluetooth (BLE) remote. The BLE remote can connect to and send data simultaneously to multiple tablets/phones. The desired feature is to be able to simultaneously scroll the same text on four different-sized tablets/phones when a remote is connected. 2-File Types: Currently, we can open and save txt files. We also want the ability to open and save Doc, Docx, PDF, RTF, HTML file types with the same features. 3-Multi-Language Support: Change the application language by making a selection in the settings. 4-Adding Titles: Users should be able to add titles to the text. These titles should appear differently from the text (e.g., bold or italic). 5-Timer: There should be a timer in one corner of the screen, and the reader should be able to see this timer. 6-Video Camera Recording: Users should be able to record themselves while the text is scrolling and save it to the gallery. Bugs: 1-Pressing the back button on the tablet/phone twice in a row exits the application. 2-In the Edit section, pressing the paste button without tapping the screen exits the application. (These features will be developed for both Android and iOS.)
