FastingLady
Simple fasting tracker designed for women, helping them fast in sync with their menstrual cycle. Work with your body, not against it.
Why I built this
To get my health back on track, I turned to fasting and a low-carb diet and initially saw great results. Over time, however, I began experiencing hair loss and irregular menstrual cycles. That pushed me to dig deeper.
Through reading research studies and books (specifically Fast Like a Girl by Dr. Mindy Pelz), I learned that men and women have very different physiologies and nutritional needs. Women's bodies follow a hormonal rhythm tied to the menstrual cycle, and fasting should be adapted accordingly—not approached the same way as men's.
I built this app to help track and understand my body, so I can better anticipate changes and adjust my fasting, diet, and exercise in ways that truly support women's health—and I still use it every day.
FastingLady is perfect for
If any of these sound like you, FastingLady was made with you in mind.
- Women who want to fast in alignment with their hormonal cycle
- Women experiencing cycle irregularities or hair loss from standard fasting

- Followers of 'Fast Like a Girl' by Dr. Mindy Pelz

FastingLady vs Zero
Both apps help you track fasting sessions, but they are built for different approaches. Zero is a feature-rich, general-purpose fasting tracker with global stats and community features. FastingLady is designed specifically for women, adjusting fasting recommendations based on your menstrual cycle phases to protect your hormonal health.
FastingLady vs Fastic
Both apps assist with intermittent fasting, but Fastic is a broad wellness app with calorie tracking, recipe books, and step counting. FastingLady focuses purely on fasting in harmony with your menstrual cycle, avoiding calorie obsession and complex feature bloat.
Frequently Asked Questions
- Why does fasting need to be different for women?
- Women's bodies are governed by a delicate rhythm of estrogen, progesterone, and LH. Constant, long-duration fasting can signal starvation to the brain, disrupting hormone production and leading to symptoms like irregular cycles or hair loss. FastingLady helps you adjust your fasting window according to your cycle phase.
- Is FastingLady based on 'Fast Like a Girl'?
- Yes! FastingLady is heavily inspired by the cycle-syncing principles in Dr. Mindy Pelz's book, 'Fast Like a Girl'. It simplifies the process by categorizing your cycle days into the Power Phase, Manifestation Phase, and Nurture Phase, advising you on the ideal fasting lengths for each.
- Do I have to log my food or calories?
- No. FastingLady believes in building a healthy relationship with your body. We focus entirely on fasting schedules and cycle synchronization, keeping the app free of calorie counting and food logs.
- Can I use FastingLady if my cycles are irregular?
- Yes. You can manually adjust your cycle length or log the start of your period at any time, and the app will recalculate your cycle days and recommend fasting protocols accordingly.
- Is there a free trial?
- FastingLady is free to download and offers a fully functional fasting timer. Premium features, including full cycle-syncing insights, personalized recommendations, and the companion Apple Watch app, are available via subscription.
