## Description

Thunderstorm Lite is a user-friendly Chrome extension designed to calculate the distance of a thunderstorm by measuring the time difference between a lightning flash and its corresponding thunder. Simply tap the 'Lightning' button when you see a flash, then tap the 'Thunder' button when you hear the thunder. The app calculates the distance using the speed of sound, providing results in metric or imperial units, which you can toggle by tapping the displayed distance.

Additionally, Thunderstorm Lite maintains a history list of measurements, allowing you to track whether the storm is approaching or receding. This freeware extension is ad-supported and perfect for users wanting quick and easy storm distance assessments right from their browser.
