Google has announced that they have ceased support for Chrome Packaged Apps (or Chrome Apps) on the ChromeOS (Chromebook) platform. Google’s recommended replacement for a Chrome App is called a Progressive Web App (or PWA).

To continue to provide data collection support on Chromebooks, we have transitioned our apps for Chromebooks to the Progressive Web App format. Vernier’s PWAs are launched by pointing your Chrome web browser to a specific URL as noted below:

• Graphical Analysis (and Graphical Analysis Pro) — https://graphicalanalysis.app
• Spectral Analysis — https://spectralanalysis.app
• Instrumental Analysis — PWA coming late spring or early summer 2025
• Vernier Video Analysis — https://videoanalysis.app (valid license key required to use this app)

Note: Use of Vernier PWAs require that IT administrators allow access to the .app domain. PWAs can be installed for simpler access if desired.

Even though the app is delivered from a domain, Vernier PWAs run locally, and no user information is ever uploaded to Vernier servers. This means that once activated, Vernier apps can be used while your Chromebook is offline.^*

^*For-purchase apps, Graphical Analysis Pro and Vernier Video Analysis, require internet connectivity at least once every 14 days to verify the purchased license is still active. All apps need internet connectivity to check for updates.
