fabm.app

A free way
to chart
your cycle.

A daily cycle tracker for everyone. Made for Title X family-planning clinics, taught in plain language, and free for as long as you need it.

We're finalizing the design so we can offer the app safely. Sign up to hear when it's ready.

Free forever No account Works on any phone

Your answers stay on your phone. We never see them. No sign-up. No tracking. No analytics. No ads.

Made for everyone.

Cycle apps are expensive, complicated, and built around ads. fabm.app is none of those.

  1. 01

    Free forever.

    Grant-funded by the RRM Foundation, a 501(c)(3) nonprofit. No subscription. No paywall. No in-app purchases. No upsell. If a paid tool ever ships, it lives somewhere else, not here.

  2. 02

    Private by default.

    Your cycle data is yours. fabm.app keeps it on your phone, in your browser. We do not have an account system, a server, or an analytics tool that could see your answers. Clearing your browser data clears the app.

  3. 03

    Plain language.

    Two boxes a day. No acronyms, no Latin, no medical jargon. The interface is the instruction. We write the way a friend would explain it, because that is how it should be explained.

How it works.

The whole thing takes under a minute a day. You read your body, you tap two boxes, the app reads the pattern.

  1. Step 01

    Open the app.

    Type fabm.app into your phone. No download. No account. Add it to your home screen if you want.

  2. Step 02

    Tap two boxes.

    Did you check for mucus today? Did you see any? Two yes/no taps. Done.

  3. Step 03

    See your pattern.

    The app tells you whether today reads as fertile or dry, based on the method you picked. Your history is always one tap away.

Questions people ask.

Is fabm.app birth control?

No. fabm.app is a tracker. It helps you learn the pattern of your cycle by recording two yes/no observations a day. It does not predict, diagnose, or replace medical advice. If you want to use fertility awareness as your method of family planning, learn the method from a qualified instructor first.

Will you see my answers?

No. fabm.app does not have a server that stores your daily check-ins. Your answers live in your phone's browser storage. We cannot read them, search them, or share them, because they never leave your device. Clearing your browser storage clears the app.

Is it really free?

Yes. fabm.app is funded by the RRM Foundation, a 501(c)(3) nonprofit. There are no subscriptions, no in-app purchases, no ads, no upgrade prompts, and no email asking you to "go premium." If we ever add a paid feature, it will live on a separate page and you can ignore it.

What is FABM?

FABM stands for Fertility Awareness-Based Methods. These are evidence-based ways of identifying the fertile and infertile days of a cycle, using daily observations of cervical mucus, basal body temperature, or both. fabm.app starts with the simplest version: a daily check for mucus.

You can read more about FABM at RRM Academy.

Can my clinic offer fabm.app to patients?

Yes. fabm.app was designed with Title X family-planning clinics in mind. There is nothing to license, nothing to install, and no patient data flowing back to us. Email us and we will send you a clinic-friendly one-pager and walk you through it.

Does fabm.app work offline?

After the first visit, yes. fabm.app installs a tiny service worker so the next time you open it, it loads from your phone, even without service. Your daily check-in works the same way: it writes to your phone's local storage, no internet needed.

Why this exists

Built by the RRM Foundation.

fabm.app is built and maintained by the RRM Foundation, a 501(c)(3) nonprofit (EIN 93-4594315). We make restorative reproductive medicine education free, plain-language, and accessible to the people who have been priced out of fertility care.

Your data stays on your phone.
That is the only kind of cycle tracker we are interested in building.
