My Signal Tracker is a free mobile app that provides users with real-time and historical data on their mobile network signal strength. Developed by M2Catalyst LLC., this app helps users find the best signal strength for their mobile network by providing a personal cell coverage map. With this map, users can view their cell phone coverage heat map for 2G, 3G, and 4G LTE and see real-time personal cellular network signal information. This app also enables users to view historical data on their network signal strength. The data is available for 2G, 3G, and 4G networks and can be viewed on a daily, weekly, monthly, and all-time basis.

The app also includes a crowdsourced network coverage map that helps users find areas of better coverage near them. The crowdsourced map can be filtered by network type and mobile network operator. Users can compare their personal coverage readings with the crowdsourced readings from others. The more contributing members the app has, the greater the coverage and accuracy of the information provided. My Signal Tracker never collects email or phone numbers, but it does collect location and network performance information, which is licensed to mobile network operators and cell tower owners to improve network coverage and performance.
