If you're looking to Download GRS on your Chromebook laptop Then read the following guideline.

This app supplements the online GRS10 version and is included with GRS10 Digital and GRS10 Complete subscriptions. GRS10 subscribers log into the App using their GeriatricsCareOnline username and password. Subscribers can use the GRS - 10th Edition App to access all online functionalities of the GRS10, including the ability to take practice tests, and tests for CME credits (please note that the MOC exam is NOT available through the app; MOC exams must be taken on GeriatricsCareOnline). Please note that once a CME test is started using the app, it must be completed and submitted through the app. Tests started in the app cannot be accessed through the digital subscription on GeriatricsCareOnline.
