PeriFlow Perimenopause Tracker

Perimenopause changes everything - your cycle, your weight, your energy. PeriFlow tracks your phase and adapts your nutrition, fasting window, and symptom plan to match. Built for irregular cycles. Built for perimenopause.
Most cycle tracking apps were built for 28-day cycles and ovulation windows - not for the shifting cycle lengths and unpredictable symptoms of perimenopause.
PeriFlow is built for women aged 38-55. Every recommendation - what to eat, when to fast, how to move, which symptoms to track - is tied to your current hormonal phase, even when that phase is hard to identify.
Phase Tracking That Works for Irregular Cycles
PeriFlow identifies your current cycle phase - Rise, Crest, or Root - from your logged data, even when your cycle is longer, shorter, or unpredictable. As perimenopause progresses, cycles naturally become more variable. PeriFlow is built to handle that variability, not ignore it.
Nutrition Adapted to Your Phase
Estrogen and progesterone shift how your body uses carbohydrates, metabolises fat, and responds to protein. PeriFlow serves daily nutrition guidance calibrated to your current phase - your Root phase, when progesterone is higher, calls for different foods than your Rise phase, when estrogen is building.
Fasting Windows Built for Perimenopause
Intermittent fasting works differently across your hormonal phase. Long fasting windows in your luteal phase can raise cortisol, disrupt sleep, and stall fat metabolism - the opposite of the intended effect. PeriFlow adjusts your fasting window to your phase: wider in Rise when estrogen supports insulin sensitivity, moderate in Root when your body needs less metabolic stress. Fasting smarter, not longer.
Symptom Tracking and Pattern Recognition
Log brain fog, hot flashes, poor sleep, mood shifts, bloating, low energy - or any symptom you're experiencing. Over time, PeriFlow surfaces the patterns - which symptoms cluster in which phase, whether your nutrition changes have reduced their frequency, and what your individual hormonal signature looks like. This is the data you bring to your GP appointment.
Phase Matched Movement
High-intensity training when your body is in a progesterone-dominant phase can increase cortisol and trigger inflammation. PeriFlow recommends movement that matches where you are: strength and intensity work in your Rise phase, more restorative and moderate movement in your Root phase.
Grounded in reproductive endocrinology, not generic wellness.
PeriFlow's recommendations are grounded in how estrogen affects insulin sensitivity, how progesterone shapes cortisol and sleep, and how both shift across an irregular cycle. Not cycle syncing for a 28-day cycle - perimenopause-specific tracking.

Your cycle has become unpredictable - longer, shorter, or skipping

You've tried intermittent fasting and found it backfires in certain weeks
