Women Don’t Give Up on Tracking
Tracking Gives Up on Them

Other Trackers Fail Women. Daysy doesn’t.

Most tracking tools weren’t built for real bodies or real life.  Here's why.

Most tracking tools weren’t built for real bodies, or real life.

Here's why.  

Accuracy That Feels Like a Guessing Game

Most tracking apps just count days and assume your cycle follows a perfect pattern

But only 13% of women actually have a 28-day cycle.

 

That means the rest of us are left with confusion, mixed messages, and missed timing
Title

Privacy? What Privacy?

Your cycle data isn’t a product - it’s yours - but most apps dont treat it that way.

67% of tracking apps have shared user data with third parties


You deserve a device that keeps it private, safe, and offline

It’s Complicated, Costly, and Tedious

Hormone strips, subscriptions, syncing apps, endless charts...


You’re already managing enough


You shouldn’t need a subscription and a science degree just to understand your body

No Room for Real Life

Early meetings. Late nights. A toddler who didn’t get the memo...


Real life isn’t always cycle-friendly. It’s messy, magical, and yours.


And yet most fertility tools expect you to run like clockwork

One-Size Fits… No One

Irregular cycles, perimenopause, PCOS - your body doesn’t follow a script.


Most trackers are built for predictability, not for people.


So when things shift, you’re left with blanks - or worse - misinformation.
Title

Where’s the Science and the Support?

Some tools are reliable, but rigid. Others are simple, but not precise.


You shouldn’t have to choose between clinical credibility and real-world simplicity.


What you need is both - scientific depth and everyday ease.
