Field staff often ask how much data the ClockShark mobile app uses. You'll be glad to hear that ClockShark uses an extremely small amount of data. ClockShark generally uses only a few megabytes of data per month to send in punches and GPS locations. This is a very small fraction of a typical data plan. Other time tracking apps can use up half of your employees' data plans in a single month, but not ClockShark.
So you and your employees can rest assured that ClockShark will not use up your employee's data plans!
