Nuvo calculates your biological age directly from Apple Health data and optional blood tests — then shows you exactly which habits are actually lowering your age. What you get: Instant biological age + pace of aging, daily recovery and strain scores, intervention logging like sauna and cold plunge to learn their real impact on recovery, embedded personalized AI insights to improve, and more. Nuvo was built privacy-first for people who want to lower their biological age — not just measure it.
