Abstract: Devices, systems, computer program products and methods for detecting gunshots is provided. The method and associated system can include a device which is coupled to a user or firearm. The device can include an accelerometer and a microphone for detecting movements and sounds, respectively. The device can be trained by firing rounds from the firearm under predetermined conditions. Analysis of the training results in creating a data signature for the particular firearm. Gunshots can be then detected by using the data signature and comparing the data signature to the movements and/or sounds captured. The number of rounds left in the firearm can then be displayed to the user for easy viewing.
