Ripl is currently available on iOS mobile devices and tablets running iOS 8 and higher. Unfortunetly, Ripl does not run on your desktop.
Our android version is currently an early Beta release available on mobile devices running android 6.0 or higher. Because it's an early Beta release, it's missing some of the free and Ripl Pro premium features available in our iOS product. We're building out new features and addressing small bugs as fast as possible through app updates.
