Described herein are methods and systems for limiting functionality of a smartphone by an administrator device based on the speed of the smartphone, which can indicate that the smartphone owner is driving. In some embodiments, the smartphone can be configured to launch a blocking application as the default home screen application. The blocking application can be used to pair the smartphone to the administrator device. The smartphone can receive a velocity threshold and an allowed application list from the administrator device. The smartphone can determine that the velocity of the smartphone, based on GPS data, exceeds the velocity threshold. The blocking application can enable a block mode on the smartphone in response to determining that the velocity exceeds the velocity threshold. Enabling the block mode can include disabling access to applications that are not in the allowed application list, thereby limiting distractions caused by the smartphone for the driver.
