An is not another dashboard of charts. It is an analysis layer above the devices people already own. An follows how each person's health signals evolve against their own baseline, and reports periodically, in plain language: what is changing, how confident the analysis is, and what should happen next.
An is software only; we do not make hardware. The more data a family chooses to connect, the deeper the analysis can responsibly go. For people without devices, an optional voice check-in keeps them within the circle of care. Voice is an input channel — never the center of the product.
Apple Health and Health Connect: activity, mobility and walking patterns. Sufficient for movement trends — not yet health analysis.
Heart rate, heart-rate variability, sleep, blood oxygen (SpO2), respiratory rate and temperature deviation. This tier unlocks longitudinal trend analysis against a personal baseline.
Blood pressure first — the most valuable clinical anchor for cardiometabolic risk — together with weight, and blood glucose where a clinician advises it.
HbA1c, blood lipids, kidney function and further results imported from laboratory files, together with age, existing conditions, medication and family history. Only at this depth does risk assessment become meaningful.
Users and partner clinicians confirm which signals proved real. Every confirmed outcome recalibrates the engine. Reliability is earned from evidence — never asserted.
Each person receiving care — a father, a mother, grandparents, or yourself — has an individual profile, with separate data sources and separate consent.
Siblings and relatives join the family circle at no cost, on iOS or Android. Pricing is based on the number of monitored profiles and the depth of analysis — never on the number of viewers.
The person being monitored decides what is shared — summaries only, urgent alerts, or full detail — and may withdraw access at any time. Paying for a parent's care does not confer ownership of their data.
An exists to serve a community. Its pricing follows the same principle:
Core safety functions — basic reminders, serious-deviation alerts and family connection — are never withheld behind a paywall, and are never marketed through fear.
Depth: richer periodic analysis, more profiles and devices, longer history, and human review of unusual cases at higher tiers.
Health data needs time to become meaningful. Families begin with a 30-day cycle: a baseline period, followed by the first in-depth analysis report at no charge. The decision to pay comes after An has shown what it can find.
A share of subscription revenue maintains a free community tier for older people living alone or on low incomes, delivered with local partners.
50–100 families in Ho Chi Minh City: baseline building, the first in-depth analysis reports, and measured validation with clinician feedback.
Launch on the App Store and Google Play, in Vietnamese and English, with the family model described above.
The architecture is multi-market from day one: multilingual by design, risk calibration per population, and health-data compliance per country. The Vietnamese diaspora — adult children paying for their parents' care from abroad — is the natural first bridge.
