How accurate is this app at predicting your ovulation?

Question

I’m wondering how accurate this app is at predicting ovulation? Has anyone gotten slightly different results from either testing or getting pregnant on a day the app said you weren’t fertile? Just curious! It’s definitely helpful having it as an estimate but I want to know how seriously I should take it

Answer

If I had listened to the app, I would have completely missed my fertile window entirely. I ovulated on CD17 and the app didn’t have me ovulating until almost a whole week later. 
The app uses the outdated calendar method to predict ovulation. Unless you have a perfectly regular cycle and a perfect 14 day luteal phase, it’s not going to be very accurate.

Answer

It’s a hit or miss for me. When I started testing with opk’s I learned it was a day or two off but not drastic. Baby dust!

Answer

The more that you put in your data, the more accurate it will be. Try to log everyday for a month or two and it should be a pretty good prediction. After a couple of months of tracking my period and ovulation (with opks) the app is usually only off by about a day
