Call Timer is a free and simple call time application developed by L. Todd Dugan for Android users. It helps users manage their call time by automatically hanging up calls after a set amount of time when enabled.

One of the main features of this application is that it vibrates and beeps at a user-defined amount of time prior to hanging up, giving the user enough time to wrap up the conversation or extend the timer if necessary. Additionally, there is an ongoing notification with a countdown, which makes it easy for the user to keep track of the remaining call time. If the user wants to stop the timer, there is a notification button available for that, and if they need more time, they can extend the timer using another notification button.
