The 94.5 PST (WPST) app is a free multimedia application for Android devices that provides users with the latest news, weather coverage, and traffic updates in the Princeton area. Developed by Townsquare Media Inc., this app allows users to listen to the station live and interact with the hosts, including the ability to direct message and call the show directly from the app. The app also offers the latest news, videos, photo galleries, and audio content, as well as the ability to submit photos and videos directly from the app.

In addition, users can participate in contests and giveaways, get exclusive access to station scavenger hunts, and receive instant alerts for breaking news, weather, contests, shows, and more. The app features full multi-tasking with background audio and controls, and supports Chromecast for wireless streaming to compatible devices. Users can also save articles for reading later, even in offline mode, and share the latest news on Facebook and Twitter. This is the latest version of the app, and more features are already planned.
