Whadup
Read full descriptionHide full description
Something's on in Leuven. See who's going. Whadup shows what's happening in the city today, and the people who'll actually be there. Not a list of events. Plans with faces attached. Got an idea? Post it in seconds. Coffee tomorrow, a volleyball game, drinks after work, anyone can start a plan! Every plan has its own chat, so you know the vibe and a few names before you show up. Communities for the things you keep coming back to: bouldering, languages, volley board games, internationals, etc.. so the same faces keep turning up. Less scrolling. More actually going. Whadup is in beta in Leuven, Belgium. Every account is checked by hand. No bots, no randoms from three countries away.

Sync

Sync is for people who would rather have one good conversation tonight than a week of typing that goes nowhere. Most social apps are built to keep you scrolling. Sync is built to get you off your phone and talking to someone who is actually in the room with you. There is no feed to scroll. There is no messaging in Sync. If you want to talk to someone, you go and talk to them. HOW IT WORKS 1. Find somewhere to go. Sync opens on what is on near you: venues, events and nights out you can actually turn up to. Browse the map, or scan today, this week and the weekend. 2. Check in when you get there. Checking in is the thing that makes you visible, and it puts you in front of the people checked in at the same place. 3. See who is in the room. Not a browsable list of the whole city. Not people who might show up later. The people who are here, now. 4. Wave. If someone looks worth talking to, you wave at them. It is a low-pressure "come say hi", not a message. 5. Go say hi. If they wave back, that is your green light. Sync tells you both, then gets out of the way. The conversation happens in person, or it does not happen at all. IF YOU NEED AN OPENER Profiles in the room carry a couple of icebreakers, pulled from something you and the other person actually have in common. And if the two of you share a friend, Sync will say so and let you guess who: an interest, then a first letter, then the name. Some events let the organiser open a short window beforehand, so people going that night can look through who else is going and match ahead of doors. That window is the one exception. Everywhere else it is the room you are standing in, or nothing. AFTER THE NIGHT Sync asks one question afterwards: did you have a good time, and did you meet anyone new. Answering it opens that night's people in Connections. From there you send a Sync request to anyone worth keeping, and swap whichever socials you choose to share. Anyone you do not convert quietly ages out. Sync does not keep a permanent roster of everyone you once stood near. WHAT SYNC DOES NOT DO No messaging. No feed. No browsing people who are not in the room with you. Those are not features we have not got round to. Each one is a place a normal app would try to hold on to you, and Sync would rather hand you back to the room. NOTHING TO BUY Sync is free to download and there is nothing to buy inside it. No subscription, no boosts, no paying to be seen. Where an event sells tickets, the organiser sells them; it is never an in-app purchase. YOUR CONTROLS You decide when you check in, and checking in is what puts you in a room. You can block or report anyone from their profile. You can export your data or delete your account from inside the app. Go somewhere. Check in. See who else showed up. Go say hi.

Verdict
The clearest difference is update cadence: Whadup at every 2 days against Sync's weekly. Whadup also leads on iOS requirement (15.0.0 vs 17.2). On price, ads, in-app purchases and device support there is nothing between them.
