FAQ

Your most common questions, answered.

Whether you’re just getting started with HiaFan or exploring what we offer, we’ve answered the most common questions right here.

Is HiaFan a sports betting app?

No. There is no wagering, no money on the line, and no gambling of any kind on HiaFan. HiaFan is built entirely around knowledge, reputation, and bragging rights. Your predictions earn you a score.

What makes HiaFan predictions different?

HiaFan predictions are made in plain language. You're not choosing from a list, tapping yes or no, or snapping together predefined options. You call the game the way you actually see it, in your own words, with your own reasoning. That's what separates real fans from casual ones, and it's exactly what HiaFan was built around.

How does the Ball Knowledge Score work?

Every prediction you make contributes to your BK Score, a cumulative measure of your sports intelligence built across every game you engage with. The stronger your calls over time, the higher your score climbs. It is your permanent record on HiaFan.

What sports does HiaFan cover?

HiaFan launches with Basketball (NBA, WNBA, CBB, WBB), Soccer (Premier League, Champions League, La Liga, Bundesliga, MLS), Football (NFL, CFB), and Baseball (MLB). We are continuing to expand from there with more sports on the roadmap.
