Wearables
Connect the apps you already use. Terra is the backend — this catalog is not a Terra rename. Wearable minutes never subtract years from biological age.
Trackers stay empty until connected. They never subtract years from biological age.
Overall age uses the published nine-marker blood method (Liu 2019 ALP 0.00188). A complete panel is your biological age; missing markers stay an estimate with a ± band. System tiles are health proxies (0–100 · band), not organ years. Specialty clocks stay dark without those tests.
