One exhausted family who spent thousands of dollars flying across the country visiting colleges with their high school student. After waiting for 1.5 years (yup, some bookings are done 1.5 years in advance), they were herded en masse across various campuses in generic guided tours. For the high school student, he learned little about the colleges (hard to hear over all the people on the tour), couldn’t ask specifc questions about life on campus (again, too many people), or questions about the major he wanted to study (colleges don’t offer subject-specific tours). For the parents, with all the money and vacation days spent, they had on their hands a tired high school student and a really bored younger sibling! There has to be an easier and more affordable approach to college visits! An idea was born. At Quads U, connect with a college student at a college you want, a major you are interested in – get the inside scoop about campus life, academic environment, application process – ask away!

Verdict
The clearest difference is rating: QuadsU at 5.0 against Hello Nabu's 4.3. QuadsU also leads on update cadence (every 4 days vs every 3 weeks) and monetization model (free vs ad-supported). Hello Nabu's advantage is ratings volume (7 vs 1). On price, ads, in-app purchases and device support there is nothing between them.
