We don't have a Chrome app for use on Chromebooks however you can access Komodo via our web app using the instructions below.
To begin, navigate to https://app.komodomath.com/iapp/. This will bring you to our web app.
If you see a blank screen like below, simply click on the flash logo and select "Allow".
You should now be able to use Komodo without issue in your browser. We would also recommend bookmarking the web app so it's easy to find next time!
