Tide is a free, students-only social app for meeting people on your campus. Every account is verified with a .edu email, so there are no bots or strangers. You get one interest-matched student a day, group chats for your actual classes, an optionally-anonymous campus feed, and 5-digit friend codes. It's on iOS, the web, with Android next. Your data is never sold.
Tide is a students-only app built to help you actually meet people on your campus — not doomscroll an anonymous gossip feed. Below are the questions students ask most before signing up, answered straight. If you'd rather just try it, you can open the web app or join the iOS beta.
Is Tide free?
Yes. Tide is completely free to download and use. There's no paywall, no premium tier hiding the good features, and no "unlock matches for $9.99." It was built by a UC San Diego student who found a 30,000-person school weirdly lonely, not as a business trying to charge you to make friends. If that ever changes, the core of meeting people on your campus stays free.
Is Tide anonymous?
Partly, and on your terms. The daily match, class group chats, and friend connections use your real-but-optional identity — you pick a public handle, and your real name is only shown to people you've actually become friends with. The campus feed lets you post anonymously when you want to ask something awkward or vent without your name on it. So it's not an anonymous app like Sidechat or Yik Yak; it's an app where anonymity is one tool, not the whole point.
How does .edu verification work?
To join, you sign in with your school email — either through your university's Microsoft or Google login, or by getting a one-time code sent to your .edu address. That email check is what keeps Tide students-only: if you can't prove you're at a real college, you don't get in. We confirm your school from the email domain (so a @ucsd.edu address puts you on the UC San Diego campus) and we don't store your password — the login happens through your school or a one-time code. There's also an optional student-ID check that adds a "Verified" badge; that ID image is scanned on your device and never uploaded or stored.
Is the daily match real students?
Yes — every match is a real, .edu-verified person on your campus, not a bot or a recycled profile. Once a day, Tide introduces you to one other student matched on shared interests and classes. One a day, on purpose: it's enough to actually start a conversation, and not so many that it turns into a swipe grind. You can read more about how it works on the Daily Tide page.
Is Tide safe?
Safety is the reason the whole app is gated behind .edu verification. Because everyone is a verified student, you're not talking to strangers, bots, or people pretending to be 19. There's no public broadcast to the whole internet — your activity stays within your campus. You can block and report anyone, anonymous posts can still be moderated and traced if someone abuses them, and we're continually tightening this. There's more detail on our trust and safety page. Tide is built for meeting people, which only works if it feels safe to do so.
Which schools is Tide on?
Tide is live across University of California campuses, including UC San Diego, UCLA, UC Irvine, and UC Davis, and is expanding to more US colleges. Course catalogs and campus pages already cover a wide range of schools so class group chats work the day students arrive. You can check whether your school is set up on the campuses page. If your campus isn't fully live yet, you can still sign up with your .edu email and help seed it.
Is Tide only iOS? Is there a web version or Android?
There's a web app and an iOS app, with Android on the way. You can use Tide right now in your browser at the web app — same login, same live data as iOS. The iPhone app is in TestFlight beta; you can join the beta here. Android isn't out yet, but it's the next client we're building, and because everything runs on one shared backend, your account and friends will carry over.
How is Tide different from Sidechat, Fizz, and Yik Yak?
Those apps are mostly anonymous feeds — you scroll posts and comments from people you'll never actually meet. Tide is built for the opposite: to get you off the feed and into real conversations with people in your classes and on your campus. Here's the short version:
| Tide | Sidechat / Fizz / Yik Yak | |
|---|---|---|
| Main goal | Meet people you can actually hang out with | Read and post anonymous campus gossip |
| Identity | Real-but-optional; anonymous when you choose | Anonymous by default |
| Verification | Every user is .edu-verified | Email-gated, but it's a feed of strangers |
| Meeting people | Daily match, class chats, friend codes | Not really the point |
| Cost | Free | Free |

Can non-students join Tide?
No. Tide is students-only by design. You need a valid .edu email from a supported college to get in, and the optional student-ID check helps distinguish current students from alumni or staff. That's the whole point — it keeps the app to actual people at your school. No outsiders, no recruiters, no random adults sliding into your campus.
How do I get my school on Tide?
The fastest way is to sign up with your .edu email. When students from a new campus join, that campus starts coming to life. If your school's catalog or campus page isn't fully set up yet, signing up still works and helps us prioritize it. We're rolling out new campuses based on where students are actually showing up, so getting your friends to join with their .edu addresses is the real lever. You can browse what's live on the campuses page.
Is my data sold?
No. Tide does not sell your data, and the business isn't built on advertising to you. We collect what's needed to run the app — your school email to verify you, your profile, your messages and matches — and that's it. Anonymous posts aren't tied to your name in public. Because there are no ads and no data brokers in the model, there's no incentive to harvest you. The full details are in our privacy policy.
How do friend codes work?
Every account gets a 5-digit friend code. Meet someone in real life — in class, at an event, wherever — and you can add each other instantly by trading codes, no awkward "what's your Instagram, let me spell it" moment. It's a clean way to turn an in-person introduction into a real connection on the app.
What can I actually do on Tide?
Four main things: get one interest-matched student a day through the Daily Tide; find and chat with people in your actual classes; see and post to your campus feed (anonymously or not); and find what's happening through campus events. All of it is scoped to verified students at your school. New here? Start with our guides on how to make friends in college and how to meet people in your classes.
Still deciding? The honest pitch is simple: college can feel huge and lonely even when you're surrounded by thousands of people — a Harvard Making Caring Common survey in 2021 found 36% of Americans reported serious loneliness, with young adults among the hardest hit. Tide exists to make the people around you reachable. Open the web app or grab the iOS beta and see for yourself.
