Your school's dining hours, class schedules, campus maps, and more. Entirely customizable. Instantly accessible. All in one spot. (*mic drop*) THE PROBLEM: You're a college student. You're juggling a million things on campus. You're tired of googling your school's dining menus, dining hours, campus maps, schedules, grades, etc. Every. Single. Day. And your school's website and apps just aren't cutting it. We get it. We've been there. THE SOLUTION: Onespot Campus is *finally* an actually-useful campus app. We know that it's actually useful because it is made & maintained by you and your fellow students. So it has everything you could possibly want to help you navigate campus life at your college. And if you're involved in a group on campus that's not yet included in the app (e.g. the juggling club, the swim team, the student government, or your emo rock band that definitely is going to get some gigs this year...), you can create a whole spot specific to that group. Then other students on your campus can join that spot to get more info about your group, message you, receive notifications, see how cool you are, and really anything else you'd want. It's like your own app-within-an-app. App-ception, if you will. Maybe the student events committee will finally book your emo rock band now that you have your own app. Enjoy!

Verdict
The clearest difference is in-app purchases: Onespot Campus at none against Power Electronics's 6. Onespot Campus also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). Power Electronics's advantage is update cadence (every 2 months vs every 9 months). On price, rating, ratings volume and ads there is nothing between them.
