A mobile device and method for determining power tool attendance. The mobile device and method are able to generate a list of power tools that are missing based on being outside of communication range with the mobile device. For example, the mobile device includes a short-range transceiver, a memory, and a processor coupled to the memory and the short-range transceiver. The processor is configured to receive a list of a first plurality of power tools and receive, via a user interface, a selection to detect nearby tools. The processor is also configured to receive, via the short-range transceiver, identification signals from a second plurality of power tools and determine that a subset of the first plurality of power tools is missing based on the identification signals. The processor is further configured to generate an indication that the subset of the first plurality of power tools is missing.
