Free longevity tool

Longevity readiness assessment

Check which evidence lanes are ready before a longevity conversation. It names missing inputs and does not estimate biological age, order labs, or make clinical risk claims.

Tool rhythm

Use the tool, then carry forwardthe context that matters.

Each page turns a narrow question into clearer prep: what you entered, what is still missing, and what would be worth discussing with a licensed clinician.

Open the tool

In practice

Start with the numbers, notes, or checklist items you already have.
Treat the result as education and visit prep, not a medical decision.
Use the handoff when your own records can add useful context.

Interactive worksheet

Work the question here, then decide what to carry forward.

Each public tool keeps the input, result, source basis, and safety boundary in one place. When your own records matter, sign in and bring the context into Ojava Coach.

Longevity readiness assessment

71/100Longevity evidence is partially ready

Recovery and sleep context: readiness or recovery, resting heart rate
Body composition trend: weight, body fat, waist
Appearance and skin context: dated appearance notes, sleep, stress, or nutrition context

Evidence readiness only: not a diagnosis, biological-age guarantee, photo read, treatment plan, lab order, prescription, or clinical risk score.

Use it well

Enter the values or context you already have.
Review the local result before sign-in.
Use the Coach handoff only when you want a deeper record-aware conversation.

The clinical boundary and source basis stay attached to the result, then repeat once at the page close.

What Ojava keeps clear

A calm place to understand the pattern before your next step

Ojava organizes health records, wearable trends, medication context, and visit prep in one view. It explains what signals generally mean and keeps clinician decisions where they belong.

Start with your records Read the guides

How the pieces sit togetherThree principles

Your data stays contextual

Daily signals, accepted records, and notes are reviewed together so one lab, symptom, or wearable trend is not treated as an isolated clue.

Education before action

Ojava prepares questions and context. It does not diagnose, prescribe, dose, order labs, or replace licensed care.

One record, many moments

The same structure supports a morning check, a new lab review, and a visit packet when you need it.
