About
Lightning Distance turns the old "flash-to-bang" trick into a precise, one-tap tool. Tap when you see the flash, tap again when you hear the thunder — the app calculates how far away the storm is using the real speed of sound, with an optional temperature adjustment for even more accurate results. See it, don't just read it: your estimated distance is drawn live on a map centered on your location, so you can watch the strike radius as you count. FEATURES • One-tap timing — no math, no guessing • Live map visualization of the estimated strike radius • Metric and imperial units, detected automatically or set manually • Optional temperature calibration for more precise readings • Clean, modern design built for quick glances during a storm • No ads, no tracking, no account required Your location is only ever used to center the map — it's never stored, transmitted, or shared. Lightning Distance isn't a substitute for official severe weather warnings, but it's a fast, no-fuss way to get a sense of how close a storm really is — whether you're deciding when to head indoors or just curious after that last strike.
