WhoScored is a data-rich football app powered by Opta statistics. Its standout feature is the player rating system, scoring every performance out of ten using dozens of on-pitch actions. Match centres offer heat maps, formations and passing networks, while comparison tools suit analysts and fantasy managers. Coverage of leagues worldwide is excellent. However, the interface feels dense and dated, ads can be intrusive, and ratings favour attackers over defenders. Verdict: 5/5, highly recommended.
