Free. No ads. No account. No tracking.
Your cycle is personal. Your period app should respect that.
Meet HerFlow: a private space to understand your body, feel more prepared and help the people you love support you. Start without signing up, keep your name to yourself and track your own cycle for free.
MORE UNDERSTANDING. LESS GUESSWORK.
Get to know the patterns behind your periods, moods and energy. See what may be coming, capture how you feel and make sense of your cycle, one day at a time.
FEEL UNDERSTOOD BY THE PEOPLE YOU LOVE
Your cycle can be easier to talk about when you don't have to explain everything from scratch. Share your random code with a partner, friend or family member so they can follow your cycle phase and find thoughtful ways to support you. Choose when to share a mood or note. Pause sharing or change your code whenever you want.
SMALL DETAILS. EVERYDAY DIFFERENCE.
• Feel more prepared with a period calendar, estimated ovulation and fertile days.
• Get to know all five cycle phases with everyday self-care tips.
• Make space for how you feel: log moods, symptoms, flow and personal notes.
• Spot patterns in cycle length, period length and mood over time.
• Stay on top of your routine with period, daily check-in, medication and contraception reminders.

PRIVATE, WITHOUT THE SIGN-UP
No account or real name required. No ads, advertising tracking or usage analytics. Your name stays on your device. Sharing uses a random code: a small cycle summary is stored on our server when you set up your cycle, even before you share the code. You can turn sharing off. Moods and notes are uploaded only for days you choose to share.
FREE FOR YOUR OWN CYCLE
Personal cycle tracking is free, with no time limit. Following someone else's cycle is available through the optional People subscription, with a free 7-day trial requiring no payment, then monthly or yearly plans.
Made by one independent developer. Available on iPhone and iPad, in 15 app languages.
Get to know your cycle. Let your people get to know you better.
