Rainbow Predictor

Never miss a rainbow

Free · Designed for iPad

Never miss a rainbow. Rainbow Predictor uses weather radar and sunlight data to alert you when rainbow conditions are just right near you, or even around the world. Rainbow Predictor is a helpful guide to one of nature’s most beautiful and easy-to-miss sights. Using live radar data and sun position tracking, this app detects when and where conditions are right for a rainbow to appear and sends you a notification in real time if you are in the area.
