Help your students or speakers meet the allotted time for a lecture, conference, or other presentation. Launch the Twin Timers app on two devices: iPhone, iPad or Mac. Place one on the speaker's desk, and control it remotely from the other one, which you keep with you. The timer on the speaker's desk reminds him/her of the remaining time, turns orange and red as time approaches, and can even sound to announce the end. Time settings, timer start and stop are synchronized from your device, without you needing to reach to the speaker's desk at for each new speaker. The connection is secured by a code to avoid unwanted access.
