Rock Climber's Grade Converter app for iPhone and iPad

Free for a limited time!

Rock Climbers Grade Converter is simply the most elegant way for a rock climber to convert between grade systems from around the world. A unique and intuitive interface allows you to convert between five systems at once, and there are nine grading systems to choose from.

Just spin any of the dials and the red line on each shows you the grade conversion - simple and sweet.

Tap the gear to change modes, allowing the dials to spin independently and allowing you to select which system you want to see on each dial. Tap the gear again and voila, thats all there is to it.
