Hi, I'm Sarah
I built this because I needed it. And I figured other women might too.
Let me be real. Six months ago, I was that woman. The one with three fertility apps, a $200 monitor in her bathroom drawer, and a spreadsheet that would make an accountant proud. I was tracking everything. And I was miserable.
The apps wanted my email. My data. My money for "premium features." The monitor needed Bluetooth pairing at 6 AM before I peed. Who designs this stuff? Do they actually have ovaries?
So one Sunday afternoon—after another negative pregnancy test and a good cry—I sat down and built something simple. A calculator that just works. No login. No cloud storage. No push notifications judging my cycle length.
What makes this different:
- ✓ No account required
- ✓ Data stays on your device
- ✓ Clean, simple interface
- ✓ Free forever
- ✓ Built by someone who actually uses it
I'm not a doctor. I'm not a developer with a PhD. I'm a woman who got tired of complicated tools and built something that respects your time, your privacy, and your sanity.
Currently 14 weeks pregnant (yay!), still using my own tool to track what's left of my cycle awareness, and planning to add pregnancy-related features soon. Because the journey doesn't stop at conception.
Thanks for being here. I hope this helps you half as much as it's helped me.
