Track Perimenopause Without Trying to Remember It All
Cycles that keep moving, symptoms that come and go, and appointments months apart. A written record is the only reliable way to answer 'when did that start?'
HarmoFlux is a perimenopause tracker for recording changing cycle dates, hot flashes, night sweats, sleep, mood, energy, medications and supplements. It reviews how your recorded symptoms and cycles change over time and produces a doctor-ready summary. It does not diagnose perimenopause.

Cycles that stop being predictable
Cycle length often changes before anything else does — shorter, longer, skipped, then back again. Recording each period date gives you the actual sequence rather than an impression of it.
Symptoms commonly reported during perimenopause
- Hot flashes and night sweats.
- Disrupted sleep and early waking.
- Mood changes, irritability and anxiety.
- Brain fog and difficulty concentrating.
- Fatigue, joint aches, and changes in weight.
These are commonly reported during perimenopause, but each can have several unrelated causes. Only a qualified clinician can interpret them.
Medications and supplements, in the same place
Log what you take, when you take it, and how you felt afterwards. HarmoFlux records timing only — it does not check interactions and never claims that something you took caused a change.
A record your appointment can use
The doctor-ready PDF summary shows recent cycles, the symptoms you logged and their frequency, and your current medications and supplements — the things you are most likely to be asked about.
Private, with no advertising
- No ads, and personal health data is not sold.
- Named subprocessors and stated retention periods.
- Export or delete your data whenever you want.
It continues into menopause
Perimenopause ends; the record does not. The same history carries forward into menopause and postmenopause, so the years before remain comparable to the years after.
Common questions
What should I track during perimenopause?
Cycle dates and length, hot flashes and night sweats, sleep, mood, energy, and any medications or supplements you take. Recording the dates matters as much as the symptoms, because changes in cycle timing are often the earliest thing people notice.
Can an app tell me if I am in perimenopause?
No. HarmoFlux does not diagnose. It keeps an organized record of what you experienced so a qualified clinician has something concrete to work from.
How long should I track before an appointment?
Two to three months of entries usually shows enough of a pattern to be useful. If your appointment is sooner, bring whatever you have — a partial record still beats recalling months of symptoms on the spot.
Do I need the paid plan?
No. Cycle, symptom, medication and supplement tracking is free. Core ($1.99/month) and Plus ($4.99/month) add extra features, and there are no ads on any plan.
What happens to my record when my periods stop?
Nothing changes — you keep the same account and history and continue tracking through menopause and postmenopause.
