Pi Network says it has 300 Mainnet apps. How many are being used?

Pi Network has put a new app count at the center of its first ecosystem summit. More than 300 Mainnet apps are reported alongside a claimed audience of over 60 million engaged Pioneers, 18.1 million people who passed identity checks, and more than 420,000 nodes. None of those figures measures repeat use of an app or the value of goods and services paid for with PI. The summit provides a fresh reason to examine what a Mainnet app is and what its public record can show. Pi Network has said more than 300 Mainnet applications exist as it prepares a November developer summit, adding a new published count to its claims about the size of its ecosystem.
