Why people switch from Clue
Start without signing up
Clue asks you to make an account before you begin. HerFlow works the moment you open it, with no email, phone number, or password.
Sharing is free for you
Sharing your cycle in Clue Connect needs Clue Plus. In HerFlow, sharing your own code is free, and neither of you creates an account.
Nothing used to track you
HerFlow has no ads, no analytics, and no tracking SDKs, and its App Store privacy label lists no data used to track you.

Is HerFlow a good alternative to Clue?
Yes, if you'd rather not create an account. HerFlow needs no sign-up, declares no data used to track you on its App Store privacy label, and never links your cycle to your name. It predicts your period and fertile window, logs moods and symptoms, and explains each phase of your cycle in plain language.
Is sharing my cycle free in HerFlow?
Yes. Sharing your own cycle is free: give your random code to someone you trust and they can follow your cycle day and phase. The person following you uses the People subscription, which starts with a free 7-day trial that needs no payment.
Does HerFlow need an account like Clue?
No. There is no sign-up, login, or password, and HerFlow never needs your email, phone number, or Apple ID. You can start tracking the moment you open the app.
