For computers: Smarthinking works from the following desktop or laptop (notebook) computer operating systems: Windows (10/8.x/7.x/Vista/XP), Apple Macintosh (macOS version 10.4x or higher), Linux, and Google Chrome OS (Chromebooks). You’ll need at least 1GB memory and a Pentium Dual Core or faster processor (or equivalent).
For smartphones and tablets: You can download an optional free Smarthinking mobile app for Apple devices (iPhone®/iPad®) and Android devices. Or, if you prefer, you can use Smarthinking through your device’s web browser (for example, Safari or Google Chrome).
Internet connections: Smarthinking needs an internet connection of at least 256 kbps (which means nearly all cable and phone company connections will work as well as most satellite connections and internet-connected home wireless networks).
A technical detail you’ll probably never need to know: Smarthinking uses outbound ports 80 (HTTP) and 443 (HTTPS/XMPP).
