100 Years helps adults make sense of daily health signals. Bring together Apple Health data, manually entered records and imported reports to follow sleep, activity, body metrics and longer-term trends. See a daily summary and weekly report built from available data. Review sleep and workout patterns with their dates and sources. Explore a deterministic lifespan estimate and the factors behind it. Optional AI explanations can use an on-device model you install or a provider you configure. Cloud requests require your consent and a provider you choose. Third-party provider usage and charges are between you and that provider. The companion Apple Watch app shows a read-only snapshot sent by your iPhone. Core dashboards, manual entry, report import and JSON/CSV export are free. When a compatible model or provider is configured, the free tier includes one user-started AI analysis per day. A one-time Lifetime purchase unlocks unlimited user-started AI analyses, complete prediction history and trends, and PDF export. There is no subscription. 100 Years is intended for adults aged 18–120. Its estimates are general wellness information, not clinically validated predictions, diagnoses, treatment advice or guarantees. Consult a qualified professional for medical decisions.
