General Site is a 100% browser based application. We support recent versions of the most popular web browsers: Chrome, Safari, Firefox, and Microsoft Edge. We support these browsers on Windows, Chromebooks, Mac OS X/macOS, and Linux. We also support mobile browsers iOS Safari and Android Chrome.


Our "Assignments" feature requires a microphone. Modern HTML browsers allow us to access user microphone using only built-in technology - no plugin required. However, there are a few exceptions to our support for accessing the microphone:

  • iOS devices - Students can use Mobile Safari 11 (or newer) or use our free iOS app for taking assignments.
  • Android Devices - Students can take assignments using their Android devices. We require that Android users take assignments with the latest version of Android Chrome & Android 5.0 ("Lollipop") or higher. This functionality is in beta, but is widely used.
  • Safari for Mac - Starting with Safari 11, Safari now offers browser-only access to the microphone. Older versions of Safari do not offer browser-only microphone access. Users will be allowed to take the assignment using a Flash plugin-based microphone. Our Flash microphone works for many people, but we find it unreliable. The Flash microphone functionality will be removed in June of 2019. We recommend Safari users upgrade to version 11 or newer, or use a different browser to take assignments.


Our site and microphone technology is 100% compatible with Safari on iOS, but we also offer a free SightReadingFactory app. This app requires iOS 8.3 or later. It is compatible with iPhone, iPad, and iPod touch.
