A change in Google Play Store rules in August 2023 caused this app to be unavailable to newer versions of Android OS if the app has never been installed on that user account.

Graphical GW
Graphical GW is an older app and is only needed for Vernier Go Wireless devices (discontinued in 2018.) Most students who need to connect to Vernier sensors should instead use Graphical Analysis. Graphical GW will not be available for devices running Android 7 and newer. For those comfortable with side loading apps, you can download Graphical GW v3.2 apk. Because this application has not been updated in some time, it may not work in all situations. Upcoming changes in Android 14 will likely block the side loading of this app.
