Most health apps pick three vitals and call it a feature set. Core treats them as the bare minimum — and adds the things real health actually depends on: mental wellness, cycle, medications, and the connections between them.
HRV, SpO₂, heart rate and resting HR, weighted into a single daily score so you can see the day at a glance — and unfold it when you can't.
PHQ-9, GAD-7 and DASS-21 — the same instruments your GP uses, run on a schedule you choose, with trend lines you actually keep.
BBT, mucus and flow logging plus a phase-aware predictor for fertile windows and PMS — without selling your data to anyone.
Schedule, dose, adherence streaks and as-needed entries. No reminders that nag — reminders that respect when you've already taken it.
Tag what you're feeling — physical or mental — and Core surfaces it next to the vitals from that same day. Patterns find you.
Sleep from Somna, training load from Motion, fuel from Nourish — combined privately on-device into one signal you can trust.
