To download the latest version click on the file link below. To install it transfer the downloaded .apk file to your Android device and then change the Security setting 'Unknown source' to allow installation of apps from sources other than Google Play Store. Despite what the access permissions required show on installation the only file that is written to is /SoundScape/SS_Config.txt. The only files that are read are the sound files in the 'Sounds' directory and the SS_Config.txt file.
