Open PMOSense
Built from real PCOS experience
Built PMOSense for PCOS & irregular cycles.
I created PMOSense to make cycle and fertility tracking feel simpler, calmer, and easier to understand — with LH test scans, BBT, symptoms, cycle insights, and ovulation predictions in one place.
Built independently by Gwennie as a personal weekend project
inspired by her own PCOS and fertility journey. Designed with modern
technology and a clean, calm aesthetic. PMOSense is currently free
to use on the App Store and as a web app while it continues to
grow.
Meet PMOSense
A free cycle and fertility tracking app made for PCOS, PMOS and
irregular cycles.
Why I built it
Built from real PCOS and fertility struggles.
I built PMOSense because I personally struggled with PCOS (now
increasingly referred to as PMOS), irregular cycles, and the
emotional stress of trying to conceive while not understanding what
my body was doing.
Even with medical support, I still felt confused, overwhelmed, and
disconnected from my own cycle. I was tracking things across notes,
apps, photos, and temperature logs but never felt like I had a clear
picture.
Over time, I started building my own tracking system to better
understand patterns in my cycle, ovulation, LH tests, symptoms, and
fertility signs.
PMOSense started as a personal weekend project for myself — and
eventually became something I wanted to share with other women going
through similar experiences.
My hope is that PMOSense can help women feel a little more informed,
supported, and less alone in their fertility journey.
