Glow vs Fertility Friend vs Kindara, which should I go with?

Question

So, according to Glow, my fertile window ends today, according to Kindara it starts today, and according to FF, it starts tomorrow! Got my positive opks yesterday and the day before... Who should I believe? Been charting with glow and FF the longest

Answer

If you had a + OPK then you are about to ovulate and your fertile window is almost closed. Any app that doesn't adjust to that is inaccurate.

Answer

I prefer Glow & Ovia! They both are pretty accurate & Ovia does what Glow doesn't :)

Answer

well,  once you tell glow about your opks, it will adjust.  looks like it was pretty close even before telling it about your opks.
