Javelin readers are not available for platforms other than MS Windows, macOS, iOS/iPadOS and Android, but can often be run on other platforms if they either support a virtualization facility (e.g. the Parallels MS Windows support on macOS computers) or Android support (e.g. for many Unix-based platforms and all modern Chromebooks). For Chromebooks download the Javelin for Android app using Google Play. Javelin readers are not available for Amazon Kindle devices, but early versions of our Android reader may run on Kindle Fire devices or other Kindle devices that support Android versions.
