Find what actually helps you feel like yourself again.
A simple daily plan for food, movement and rest, built for perimenopause. As you log how you sleep and feel, PeriFlow shows you the patterns that are yours, not the average, even when your cycle has stopped making sense.
Free to start, no account needed. Your daily meal plan, cycle calendar and symptom journal stay free.
Hot flashes. Brain fog. Sleep that vanished. You're not imagining it.
In perimenopause your hormones stop following the steady pattern they used to. They swing, and the swings don't announce themselves. So the advice that worked at 35 works some weeks and not others, and nobody can tell you which. Eat 1,400 calories. Fast 16 hours. Cut carbs. Another rule isn't the answer. Noticing what changes for you is.

Your patterns
Your body, your evidence.
Log how you slept and how you feel. It takes a few taps a day. As the days add up, PeriFlow looks for links between your sleep, your meals, things like caffeine or alcohol, and your symptoms, and tells you when one holds up. A pattern only appears once there's enough data behind it, and what you do with it is yours.
Pattern spotted
After a good night, you rate your next-day energy 3.8 out of 5, against 2.1 after a poor one. Sleep quality is clearly a lever for you.
Pattern spotted
On days you log more caffeine, you rate your sleep 2.4 out of 5, against 3.6 on days with none. A pattern worth knowing — what you do with it is yours.
Examples written the way the app writes them. Your own patterns depend on what you log.
Your cycle
Your cycle as context, not a rulebook.
While your cycle still has a rhythm, it explains a lot: why you're hungrier some weeks, or why a fast feels easy one week and hard the next. PeriFlow estimates where you are from what you log and adjusts as your cycle changes. When periods become rare or stop, it leans on your symptoms instead.
Rise Phase
Often the days after your period
Many women feel their energy pick up after their period. If you like to fast, this is when a 12–16 hour overnight window tends to feel easiest.
Crest Phase
Around the middle of your cycle
A short stretch when many women notice sharper focus and more energy. PeriFlow keeps any fasting window moderate, around 12–14 hours.
Root Phase
The week or two before your period
Your body uses a little more energy before your period, and hunger often rises with it. PeriFlow pauses fasting suggestions and plans three regular meals, which many women find steadies cravings and sleep.
Strength training matters in every phase. PeriFlow keeps a twice-a-week strength minimum, whatever your cycle is doing.
Everything you need
One app. Built from the ground up for perimenopause.
Not a period tracker with a wellness coat of paint. One daily routine that adapts to your cycle, your diet and what your own data shows.
Your Own Patterns
Log your sleep, meals and symptoms, and PeriFlow shows you what tends to come before your better days, and your harder ones.
A Daily Meal Plan
122 recipes across 7 diet styles, planned around where you are in your cycle. Every meal comes with "why this meal?", the reasoning behind it.

What users say
In her own words.
Our first App Store review, verbatim. Everyone's experience is different.
I find it super helpful to know what I should eat, how to exercise and when to fast in each stage of my cycle. I love the recipe feature, it's so easy to plan my shopping list. I don't have lower back pain anymore and my night sweats are almost gone.
