There are lots of apps or related devices that just measure and track BBT. I had one 25 years ago, for heaven’s sake.
But this gizmo seems to be a good deal more comprehensive -— if it were just BBT, like what’s been out there for decades, I can’t see how they could get a patent.
As you no doubt know, there are four major hormones which interact rather complexly, with feedback loops and all, to bring you to the verge of ovulation. If this app tracks them via saliva, urine, or even vaginal secretions, it would be a huge improvement over just BBT, or subjective impressions about how how or firm or slip-slidey your cervix may be.
The article didn’t specify what-all goes into these new, improved algorithms, but it seems it’s truly not the equivalent of a sun-dial. If they’re trying to get away with fraud, I’m betting savvy NFPers would catch them early on.
I say hooray for the lady physicist and her great new gizmo.
I don’t have a problem with her profiting from it, but yes, the next step would be something you insert that gives a serious chemical / hormonal read.
I did temps for over 6 years, no preg. Infertile. Temps alone would not have cut it. Thank Gd (and I do) that I kicked infertility in the butt. Only one of my four was conceived without a lot of help.
