Ovulation date?

Kaitlin • Military wife!💍 PCOS. 👼🏼2014, 💙2017, 👼🏼2019

Has anyone gotten different dates for estimated ovulation day? My app says tomorrow but webmd says today is my estimated ovulation date. I know bodies are different and everything is estimated but was just wondering. I won’t use ovulation predictors as they aren’t accurate either really(to me they aren’t). Just wondering if anyone has gotten different dates?
