Lighting Timer Rocks

Despite the name of the app (Cliff timer, which gauges height by the time it takes a rock to land, which is itself awesome), I particularly like the Lightning timer functionality (estimating distance be the time between the lightning and the thunder), perhaps because I find myself in thunder storms more than I find myself in high places?

Thank you for your review. I’m glad you enjoy the app.

Great App

This app is fantastic. For my whole life I’ve been using the 1-Mississippi 2-Mississippi method to measure height, but 280 feet sounds like a way better height than 4-Mississippis. And it can be very useful to know how far away a storm is. Great app!

FAQ

How does Cliff Timer calculate lightning height?

Cliff Timer uses the formula h = 1/2 * g * t^2, where 'g' is the acceleration due to gravity and 't' is the time in seconds between seeing lightning and hearing thunder. The app measures this time for you.

What is the formula for lightning distance in Cliff Timer?

The app utilizes the formula d = t / 5, where 'd' is the distance in miles and 't' is the time in seconds between seeing lightning and hearing thunder. This provides a quick estimation of how far away the strike is.

Yes, Cliff Timer functions as a standalone utility app. Once installed, it does not require an internet connection to perform its calculations, making it useful even in areas with no signal.
