Fortuity Cycle

One tap logs your period. The people you choose finally know what is coming, instead of guessing.

Log a period in one tap, and five symptoms if you want them. Predictions come from your own cycles and arrive with an honest range, never a single confident date. Invite a partner or a family member to see exactly what you choose, on a page that needs no app and no account, and stop it whenever you like.

Nothing about your cycle uploads until you invite someone. No ads, ever.
The support loop

Sharing is the point, not an afterthought

Most tracking apps stop at the person doing the tracking. Fortuity Cycle is built for the people around you too, so the ones who want to help actually know what is happening.

1

You invite someone by link

A partner, a mother, a sister, a close friend. They open a web page. No app, no account, no sign-up on their end.

2

You pick what they see

Phase only, or phase and symptoms too. Each person you invite can have their own view, and you can change it whenever you want.

3

You can stop any of it instantly

One tap ends a person's access. Nothing lingers, and nothing shows again until you reopen it.

Tracking, kept simple

Restraint is the feature

Many trackers open with screen after screen of setup before you can log anything real. Fortuity Cycle opens on the one button that matters.

One tap starts a period

That is the entire log. Five symptoms are there if you want them, and nothing else competes for your attention.

Predictions from your own data

Once you have logged three cycles, predictions come from your pattern. Before that, the app uses a typical 28-day cycle and says so plainly.

An honest range, not a false date

Every prediction comes with a plus-or-minus, such as give or take two days, instead of one date presented as certain.

Works with your Apple Health history

It reads what is already there so it is useful from day one, and writes back so your record stays yours if you ever leave.

What you control

Built so your data stays yours

Cycle data is intimate. These commitments are engineered into the product, not just written down.

✦
Nothing uploads until you shareYour cycle stays on your phone by default. It reaches our servers only once you invite someone.
✦
You set the view, per personEach invited person sees only what you have chosen for them, and you can change or end it at any time.
✦
No ads on this data, everCycle data never touches an advertising network or a third-party analytics tool.
✦
Never soldYour record is not inventory. It is not shared, brokered, or sold to anyone.

Track it in seconds. Share it on your terms.

Fortuity Cycle keeps the logging small and the sharing precise, so the people around you can help with what is actually happening.
