A clearer way to measure your prime.

PrimeCheck helps everyday adults understand how their physical capabilities compare with others their age. A short set of approachable at-home tests becomes an estimated Fitness Age, a Prime Score, and a useful category breakdown.

Our mission is to make healthy aging easier to understand and more motivating to improve. The experience is simple, encouraging, and competitive—without becoming clinical or shaming.

Don't just count your years. Measure your prime.
