When I calculated that my period would fall during my holiday.

Plans should not depend on whether your body behaves like an average.

See what SEESOO sees
01 The problem with averages

Most period predictions begin with a simple calculation: your average cycle length.

There is a big gap between how dynamic women’s bodies are and how static reproductive-health tools remain.

Sees

Have you ever:

  1. 01

    stopped wearing white, just in case

  2. 02

    carried period products for ten days because the app could not narrow it down

  3. 03

    booked a trip, race, sauna, date or important meeting without knowing how you might feel

  4. 04

    struggled to remember months of symptoms during a ten-minute medical appointment

  5. 05

    wondered who else can see what you enter into your tracking app?

02 What SEESOO is

Women already generate continuous physiological data through wearables.

SEESOO not only keeps track of your period it provides you with wearable-informed period and menstrual phases predictions. It starts with what’s known about how a woman’s body changes across a cycle, then learns your version of it from your wearable. The more you use it, the more personal it becomes.

03 How SEESOO is different
01

Wearable-
informed

SEESOO looks for changes in the physiological signals your wearable already records, instead of relying only on calendar arithmetic.

02

Personal to you

It begins with research-informed cycle patterns, then adapts on your phone as it learns how your own physiology changes over time.

03

Honest about uncertainty

Bodies are not clocks. SEESOO is designed to communicate changing likelihood and confidence, rather than pretend there is one certain date.

04 Privacy is the architecture

My body.
Nobody
else’s
business.

No cloud.
No servers.
No ads.
Your data stays on your device.

All wearable and cycle data, analysis and personalisation remain on your phone.

If you connect a wearable, its manufacturer may already process data under its own terms. SEESOO cannot undo that relationship but it does not create another reproductive-health database, and it does not send anything back to your wearable.

If you like to plan, your cycle varies, and you don’t want your reproductive-health profile stored on another company’s server or used for advertising, then SEESOO is for you.

Whatever brings you to cycle tracking, your data should remain yours.
