Find out how your habits are aging you.

TrueHealth Age turns 20 science-backed questions into a single, honest number: your real health age. Then a coach-built plan to move it in the right direction — one small habit at a time.

What makes it different

No paywall. No medical claims. No upsells.

Free, forever.

The full assessment, the full coaching plan, all 11 categories, every tip in the library — free. No upgrade screens, no premium tier, no asterisks.

Educational, not diagnostic.

The app does not diagnose disease, prescribe medication, or replace a clinician. We tell you when something belongs in a doctor's office and when it belongs in a daily habit.

Coach K, not a chatbot.

Every word of coaching is written in the voice of Coach K (Keith Kravitz) — 40 years of helping people change, FDA-cleared medical device founder, host of the upcoming TrueHealth Protocols podcast. First-person, plain language, never shaming.

Built on real evidence.

Every category is grounded in current peer-reviewed research and major clinical-society guidelines. The Sleep Society for circadian rhythm. The Endocrine Society for testosterone. The American Academy of Dermatology for skin protection. We translate the science — we don't reinvent it.
