At the moment we provide a demo version for Android OS and support many devices up to the newest OS 7+ (Android 8 has not been tested yet). To download the application, follow links for portrait or landscape. To install this application, you have to enable feature ‘install apps from untrusted sources’ in settings. Note, the app takes a time for the first time start, after that, all data will be cached to boot a start.
If you download via browser, have enabled ‘untrusted installing’ feature but still can’t install/open the app, try a file browser to open the .apk file and look for ‘download folder’. This is not an issue of our app, this might be an issue of a browser.
