Thunder & Lightning for Android

This single-task app does its work exceptionally well!

Although the creators of this app call it trivial, I think it's a pretty cool little program. This would be very good for small kids who find themselves afraid of lightning. You could show them how to use the controls and soon they'd forget about being scared. This could make them feel safer at night. The app was down for quite some time. I do like the improvements. It was basic in that primitive state, but now the improvements make it look more like a professional app. Thanks for bringing it back!

This does what it says. Can't beat the price. One reviewer, that gave a 1 star rating, suggested a slew of feature requests. The requests were cool but also required a lot more work and had potential problems related to the automated features. I like this App because it is simple and to the point.

I really like it. I found out that 4 seconds is about 1 mile!

Free, does exactly as it says, and no ads. The help documentation wryly notes that you can use this as an odometer "if you happen to be traveling at precisely the speed of sound".
