The Timer app by Zoom is a simple but important tool for improving time management skills and streamlining meetings. Additionally, the app includes a stopwatch function for tracking task durations.

Timers can be set for personal use or made visible to all participants, as well as an optional audio alarm. Preset timers are available, but timers can be custom durations as well.

When a timer is active, the user that set the timer will have a large countdown appear in the corner of their video tile. Additionally, a smaller version of the same countdown will appear in the top right corner of the meeting window, staying visible and ensuring everyone stays synchronized, even if the user that set the timer is not currently visible. When time is up, the app provides visual and optional auditory alerts.

Data Security

The application uses the zoomapp:inmeeting scope to allow users to open it during Zoom meetings, as well as to display the timer as part of the participant video. The app does not share any personal data.

See the full list of Zoom Apps SDK methods accessed by this app below:

• setVirtualForeground - Displays an image in the foreground of the user’s video to demonstrate the timer to meeting participants.
• removeVirtualForeground - Removes the image which was set using setVirtualForeground from the foreground of the user’s video.
• onMyMediaChange - Notifies the app when the current user's video settings change, such as enabling or disabling video, and when the audio is muted or unmuted. This is to ensure the timer is shown with the right dimensions and aspect ratio for the user’s current video window.
• setDynamicIndicator - Used to display a timer in the top right corner of the meeting window for all participants to see.
