KIN connects that context with your training, recovery and biometric data to uncover the patterns behind your performance. Giving you a distinctive performance edge. Every check-in delivers immediate value. Your performance edge compounds. The longer you use KIN, the more it understands what drives your performance. 7 days is an advantage. 90 days is unfair.
