Most cycle apps give everyone the same template. Eira reshapes itself around your body — your tracks, your phase, your life stage.
Private by design · No ads, ever · Built in Australia
Pick the tracks that apply to you and every screen adapts — symptoms, plans, insights, even what the AI pays attention to.
Menstrual cycle, PCOS, endometriosis, perimenopause, PMDD, pregnancy, postpartum, trying to conceive, contraception & recovery — choose what applies, change anytime.
Movement, meals and nutrients matched to your cycle phase or life stage — AI-personalised around your food preferences and allergies, never against them.
Rate intensity 1–5, not just yes/no. Watch trends build across cycles — the chart most apps never give you.
"Headaches cluster in your luteal phase — 6 of 8 times." Real counts from your own logs, with AI narrating on top. Observations, never diagnoses.
A seven-day phase forecast in plain English: "Luteal until Thursday, then period likely from Friday." No surprises.
Tick off what you take each day and see it alongside your symptoms — patterns you can actually bring to a doctor.
Share exactly what you choose, track by track, with someone you trust. They see how to show up for you — never more than you've shared.
One tap builds a factual summary of your tracking for appointments. Upload letters & results and Eira reads them into plain language.
Luteal-vs-follicular mood comparison for PMDD. Hot-flush intensity tracking for perimenopause. Depth where other apps go quiet.
This is Eira's "For you today" card. Tap a phase and watch the guidance reshape — this is what personalisation actually means.
Energy is often lower now — gentle movement, warmth, and iron-rich food can help you feel better.
Tell Eira what applies to you — one track or five. This shapes everything.
Mood, symptoms, flow — and pain gets a real intensity scale, not a checkbox.
Eira counts what your body actually does and says it plainly.
Give a partner a window into how to support you — you control every track.
Most apps keep the people who love you guessing. Eira gives someone you trust their own window — showing them how to show up for you, and nothing more.
Energy dips before a period — a calm evening and something magnesium-rich would land well.
Health data this personal deserves paranoia on your behalf. Your data is never sold, never used for ads, and sharing happens only when you choose it — revocable any time, enforced on our servers, not just in the interface.
Coming soon to the App Store and Google Play.
