Lightning Distance
See how close the storm is
Free · Designed for iPad. Not verified for macOS.
Tap when you see lightning, tap again when you hear thunder — see exactly how far away the storm is, live on a map. No ads, no tracking, no account.
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.
Lightning Distance has been rebuilt from the ground up.
• Brand new design — a full-screen live map with a cleaner, more modern look
• Metric and imperial support — distances (and temperature) now shown in the units you actually use, auto-detected or set manually in Settings
• More accurate readings — improved timing precision and a corrected radius calculation on the map
• No more ads — completely ad-free, for good
Thanks for sticking with the app — this update makes it faster, clearer, and more precise than ever.
