This is a disaster prevention support app that visualizes the estimated location and danger level of lightning strikes in real time by utilizing the time difference between the light and sound of lightning.
Using it is very simple.
The user selects the direction of the lightning using the on-screen compass,
tap the button the moment they "see the lightning," and then tap again the moment they "hear the sound." The app automatically calculates the accurate distance based on the speed of sound.
The danger level is determined in three stages: "Dangerous," "Caution," and "Safe," depending on the distance from the current location. The map displays icons indicating the lightning strike location, along with the surrounding impact area and margin of error. It also features GPS location tracking, and its intuitive and easy-to-understand UI makes it user-friendly for everyone.
