This is configurable in the apps settings screen. • No Adverts from third parties. • Displays the amount of time elapsed on the main app screen, as well as the amount of time left -this can be enabled / disabled from the settings screen. • Show the actual time on the main app screen - this can be enabled / disabled from the settings screen. How does it work? The user sets the target amount of time for the class/group to perform a particular task. The countdown timer is then started. The timer can be viewed from the Apple device itself or displayed on a larger format device such as an interactive board or TV screen using screen mirroring features of the Apple Devices. If the class completes the task in the defined time limit the teacher can tap the "tick" button and the "Well Done" screen is displayed and a fanfare sound effect is played. However, if the class run out of time the Alarm rings on the clock, the clock bounces around the screen. Then either: 1. The clock explodes in a comic fashion or 2. A "Time's Up" animation is displayed. ... simply select which effect is used. This app really encourages students to complete any assigned task, the students can see graphically how much time they have left to complete the task. The user is able to pause, restart and reset the timer at any time. The app has an audible "ticking" sound when the timer is running, this can be enabled or disabled by tapping the speaker button on the apps main screen. The Fanfare and Explosion sound effects can be controlled via the audio controls on the Apple device. This is a simple but fun and engaging app to assist the teacher in their classroom management activities. As with all our apps, users are able to send feedback, make enhancement requests or report any issues directly to us from inside the app.
