Chronus Airsoft Shooting Timer is the world's first shooting timer designed specifically for airsoft guns. By connecting the sensor cord attached to the target plate to the device's headphone jack, it accurately measures shooting times. What sets this app apart is its use of dedicated sensors to reliably detect even the subtle sounds of airsoft gunshots and enhanced adjustment features for sensor sensitivity.

To cater to various competition styles, the app offers a wide range of features including sharing shooting records to social services, saving measurement records in CSV format for viewing in spreadsheet software, voice navigation (including reading out measurement times), customizable navigation voice, flexible customization of shooting rules/measurement conditions, preset registration, convenient automatic retry feature for solo practice, continuous take addition to measurement records, and penalty addition to measurement records.

Some features marked with a symbol require purchasing the "Premium version" via in-app purchase to unlock. However, basic functionality for testing and minimal shooting time measurements is available without the Premium version.
