See your symptoms in the light of your cycle.
Alchemilla tracks your symptoms, your period, and your basal temperature — then shows you the patterns tied to your cycle, in plain language. Factual, never a diagnosis, and built to be read by a professional.
iPhone · No account · Everything stays on your device.
Not another symptom list.
Most apps let you log how you feel. Alchemilla reads it against your cycle — and hands you something a doctor can act on.
Your cycle at the centre
Log your period, and Alchemilla maps every symptom to where you are in your cycle — during it, the week after, or the days before the next one. The bleeding tells it where each cycle begins and ends.
Basal temperature
Track your waking temperature and see the shift across cycles, with sourced guidance on taking a reading that counts — first thing, before you move, to two decimal places.
Patterns across cycles
Alchemilla surfaces what repeats: “your hot flashes showed up most in the days before your period — in every one of your last 3 cycles.” Correlation you can bring to a professional, never a diagnosis.
A report that's hard to dismiss
One tap turns months of logs into a clean, factual summary — cycle patterns in plain language, a symptom-by-cycle grid, and your temperature curve. Made for the appointment.
Factual, never diagnostic
Alchemilla doesn't tell you what's wrong. It reflects back exactly what you logged, organised so the patterns are visible — for you and your clinician to interpret.
Truly private
No account. No cloud. No “anonymous mode” that still uploads. Everything you log stays on your phone — there's nothing to leak because nothing ever leaves.
Walk in with the evidence.
One tap turns months of your own data into the summary a clinician actually reads: your cycle at a glance, the patterns tied to it in plain language, a symptom-by-cycle grid, and your basal-temperature curve. Every line is your logged data — sourced where it matters, and never a diagnosis. The interpretation is theirs; the evidence is yours.
- Symptom patterns mapped to your cycle phase
- Period-pain trend and basal-temperature shift, across cycles
- A symptom-by-cycle grid, aligned day by day
- Generated on-device — nothing uploaded to make it
Calm to use. Clear to read.
Months of quiet check-ins become a few screens you can actually read — and hand to someone who can help.
Track. Understand. Advocate.
Track
A calm daily check-in — your symptoms, your period, your temperature. Under a minute, no medical form.
Understand
Patterns start to surface within your first weeks, and deepen as the app sees a full cycle or two.
Advocate
Bring a clear, factual report to your appointment — and be taken seriously.
Knowledge flows in. Your data never flows out.
Alchemilla pairs your own patterns with plain-language context from the clinical literature — so you're not just tracking, you're understanding what's typical for the transition. Every fact is sourced, and none of it needs your data to leave your phone.
See the research →Your health stays on your phone.
Alchemilla has no account system and no servers that receive your health data. We don't collect it and we can't see it — so there's nothing to sell, share, or leak. Your symptoms, your cycle and your temperature never leave your phone.
The only thing that ever does is the receipt for your own purchase, so the app can unlock what you paid for — no name, no email, and none of your health data. Read exactly what that involves.
