SolarisXD/PulseSense ? reverse-engineered prompt

Build me a mobile health tracker app that works fully offline and keeps everything on the device. I want people to be able to log vitals like heart rate, blood pressure, oxygen, temperature, blood sugar, weight, and any custom readings, then see simple charts and trend warnings over time.

It should also let users manage medications with reminders, track conditions and allergies, store emergency contacts, and create a clear medical ID screen that can be shared when needed. Add a symptom and triage screen that gives basic emergency guidance based on rules, plus a drug interaction checker for common medications. Include backup and restore, PDF and CSV export, dark mode, and a smooth onboarding flow for first time users.

If it fits, support syncing with Apple Health and Google Health Connect, but keep the core experience local first and privacy focused. Make it feel polished, calm, and easy for a non technical person to use.
