Questions

Fair things to ask

Is Eira a medical app?
No β€” it's a wellness app. It never diagnoses or gives medical advice. It organises your own observations so conversations with real clinicians get better.
How is this different from Flo or Clue?
Those apps assume one standard cycle. Eira starts from your tracks β€” PCOS, perimenopause, PMDD, pregnancy and more β€” plus pain intensity tracking, computed body patterns, and partner sharing nobody else has.
Who can see my data?
You β€” and only what you explicitly share with people you choose, revocable anytime. No ads, no data sales, and deletion actually deletes. Full privacy policy.
What does the AI actually do?
Personalises your daily plan, narrates your patterns, and drafts doctor summaries β€” from your data only. It's blocked from diagnosing or advising on medication, and its numbers are computed, not invented.
When can I get it?
It's in final pre-launch build, heading to the App Store and Google Play. Tap "Get notified" below and we'll email you at launch.
