Use "Chance of Rainbow" to help find rainbows!

Type in a location, such as a city or restaurant, to see how likely you will see a rainbow there. This app predicts the rainbow percentage from 3 things: Precipitation (chance of rain), cloud coverage, and time of day. You will be more likely to see a rainbow if there is a lot of rain, a lot of sun, and if the sun is at an ideal angle in the sky (not directly overhead).

It has been my life’s work to find the pot of gold at the end of a rainbow. For years I have tried, but I have been held back by my mortal inability to predict the future. Sure, I’ve tried checking the weather. And yes, of course I’ve waiting patiently for the end of the rainstorm. But always, I’ve been too late. Everyone knows there is a finite window of time between when a rainbow appears and when the pot of gold vanishes. I have never been fast enough. UNTIL NOW. Now, I have this app, and with it, the power to predict a rainbow and get to the post of gold before time runs out. I had almost given up on my dream, but now everything has changed.

Amazing app

Really innovative idea of an app. This helped plan my next impromptu road trip. Great visuals is a plus. Thumps up to the developers.
