Weekly verdict

An on-device summary of your week — patterns, trends, what changed. Generated by Apple's on-device language model. No cloud calls.

Doctor-ready PDF

Export a clean, shareable PDF for your gynecologist or GP. Symptoms, HRT history, sleep — without medical jargon.

HealthKit native

Hot flashes, night sweats, sleep, wrist temperature, HRV — Ember reads what your iPhone and Apple Watch already know.

HRT tracking

Scan your prescription, log dose changes, see how your body responds week over week.

Widgets & Siri

Log a hot flash from your Lock Screen. Ask Siri for your weekly summary. Designed for the moments symptoms actually happen.

Private by default

Local-first SwiftData. Optional iCloud sync via your Apple ID. We have no servers, no accounts, no tracking.

Your data never leaves your iPhone.

Unless you choose to enable iCloud sync, every symptom, every note, every weekly verdict stays on your device. We don't run servers. We don't have accounts. The AI that writes your weekly summary runs on-device using Apple's Foundation Models.

What this means in practice:
  • No sign-up. No email. No password.
  • No cloud LLM calls — your symptom history is never sent to OpenAI, Anthropic, or anyone else.
  • If you turn on iCloud sync, your data is end-to-end encrypted by Apple and only readable on your devices.
