Period timing
Why does my period feel early, late or harder this month?
Cycle timing can shift with stress, sleep, illness, travel and daily recovery. FlowHer helps you compare today with your recent baseline.
Cycle health, guided by body signals
FlowHer brings period prediction, body state, recovery, live stress, sleep and Apple Watch faces into one calm daily view.


What FlowHer is
Many period apps ask you to keep entering symptoms. FlowHer starts with the same practical period tracking, then adds physiological signals from Apple Watch and HealthKit so your day feels easier to read.
See where you are in your cycle and how many days are left.
Read recovery, stress and sleep as part of the same daily picture.
Use quick records when you need them, without turning tracking into homework.
Learn
FlowHer Learn turns questions about periods, recovery, HRV, PMS, sleep, pain and body changes into plain-language articles. Keep reading when you want to understand what your body is trying to tell you, not just record another symptom.

Cycle basics

HRV
A practical explanation of heart rate variability and how Apple Watch data can support stress awareness.
Sleep

Your period does not happen in isolation. FlowHer connects cycle timing with recovery, stress, HRV, sleep and Apple Watch data so the signals are easier to read together.
Period timing
Cycle timing can shift with stress, sleep, illness, travel and daily recovery. FlowHer helps you compare today with your recent baseline.
Body State
Body State gives recovery, HRV, resting heart rate and sleep a readable daily context, so cycle tracking is not limited to calendar dates.
Apple Watch
With permission, FlowHer uses HealthKit signals from Apple Watch to surface stress, sleep and recovery trends next to your cycle forecast.
Sleep & stress
These signals do not diagnose symptoms, but they can help you notice when your body may need more recovery before or during your period.
The product is built around the daily questions users actually have: when is my period, how is my body doing, and what should I pay attention to today?
Today
See period countdown, fertile window, cycle phase and quick actions without digging through charts.
Recovery
FlowHer turns HRV, resting heart rate, sleep and recent baseline changes into readable states such as Steady or Energized.
Stress
Stress is shown as a body signal, not a judgment. You can see how recovery and sleep may affect your cycle day by day.
Reports
Cycle summaries help you notice repeated patterns across period, symptoms, sleep, stress and recovery.
Record
Track period start and end, flow, pain, mood, sex, ovulation tests and body notes with minimal friction.
Theme
Custom visual themes make health signals feel more personal on iPhone, widgets and Apple Watch.

Apple Watch
FlowHer is designed for Apple Watch users who want their most important cycle and recovery signals visible without opening a full dashboard.
Cycle countdown, body state, recovery, stress and sleep can be surfaced on watch faces.
Watch app and complications help keep the experience useful when your phone is not in your hand.
Personalized watch-face themes make the data feel warmer and easier to check.
