Where the health information comes from.
Everything in Evymi is written against published guidance. We show our sources and say clearly what the app cannot tell you.
A record, not a diagnosis.
Evymi shows you what your body is doing and offers clear context. It does not diagnose, it does not treat, and it does not replace a doctor.
When a pattern may be worth discussing, we suggest speaking to a midwife, GP or specialist. When guidance changes, we update the wording and date the review.
From what you log, to what the evidence supports.
Evymi compares your recent logs with your own earlier records. Published guidance limits what the app can say, and a weak signal stays a weak signal.
It starts with what you log.
Cycles, symptoms, sleep, medications, mood. Structured fields where they help, free text where they don't. Nothing you log is required.
We look for changes over time.
Simple, transparent statistics · rolling averages, deltas versus your own baseline, clustering across the last 30 and 90 days. No black-box scoring.
Published guidance sets the boundaries.
Patterns are read against NICE, ACOG, WHO, RCOG and BMS guidance for the module you're in. Thresholds and windows come from that guidance, not from guesswork.
We tell you when the evidence is thin.
Insights say what we've seen, how confident we are, and what we can't tell. If the signal is thin, we say so instead of guessing.
Some patterns are worth discussing.
When something warrants a conversation · pain, bleeding, low mood, red flags · we nudge you towards your GP or specialist and give you a report you can share.
We'd rather say what we don't know than pretend to know it.
The comparison starts with the details you choose to log in symptom and body-map tracking setup — see the cycle module for what we predict, and with how much confidence.
Not a medical device.
Evymi's fertility and contraceptive-adjacent features are described as awareness, not prevention. Flare alerts point to a call, not a diagnosis. Anything urgent · bleeding, pain, fever, low mood · gets a clear prompt to see a doctor.
We do not sell your health data.
Your data is yours. We don't sell it, we don't share it with advertisers, and we minimise what we store. Reports you share with a doctor are shared by you, revocably, on a link that expires.
