The XScreenSaver application is a large collection of historic and educational graphics demos. XScreenSaver is the standard screen saver collection shipped on most Linux and Unix systems. I released the first version in 1992. In 2006, I ported it to MacOS, and in 2012 I ported it to iOS. This application is not a screen saver, of course, since iOS doesn't have those. But it does let you play with the hundreds of graphics demos that are a part of the XScreenSaver collection.

PulseU is the campus events app built by a Rutgers student, for Rutgers students. Rutgers events are scattered across dozens of websites. Games on ScarletKnights.com. Fitness classes on the Rec portal. Concerts at Mason Gross, exhibitions at the Zimmerli, and talks and workshops on a different page for every school and department. PulseU pulls it all into one fast feed, so you never miss something worth showing up for. THE PULSE The biggest weekends on campus get a tab of their own. Homecoming, Rutgers Day and more come with the full schedule, every venue, and a drawn map of campus that lights up the buildings where something is on. WHAT'S INSIDE • One feed from public Rutgers sources: ScarletKnights, Rutgers Recreation, Mason Gross School of the Arts, Scarlet Arts Rx, ScarletWell, Rutgers Libraries, the Zimmerli Art Museum, Career Exploration and Success, Student Affairs, and more schools and departments • Browse today, this week or the weekend, and search by campus: College Ave, Livingston, Busch, Cook/Douglass, off-campus and online • Follow the organizations and teams you care about and get a notification when they post something new • Save events, add them to your calendar or set a reminder, and see in Alerts when one changes its time or place • Share any event or organization with a link that previews the title, time and place • Free food and paid filters • Dark mode that follows your phone NO ACCOUNT REQUIRED PulseU is free and anonymous. No sign-up, no login, and we never ask for your name or email. Saved events stay on your device. If you turn on notifications, the organizations you follow are stored with an anonymous device token, only so we can tell you when they post. ALWAYS LINKED TO THE SOURCE Every event links back to its original page. PulseU is a discovery layer, not a replacement. Always check the details before you go. RUN A CLUB, DEPARTMENT OR VENUE? Want your events featured in PulseU? Email pulseu.app@gmail.com. Not an official Rutgers University product. Event information is aggregated from public sources and may change.

Verdict
The clearest difference is rating: XScreenSaver at 4.9 against PulseU's 4.2. XScreenSaver also leads on ratings volume (106 vs 5). PulseU's advantage is update cadence (every 11 days vs every 6 months). On price, ads, in-app purchases and monetization model there is nothing between them.
