Can Ovulation Apps be trusted?

Question

Hey ladies;  I downloaded 6 ovulation apps and set my last period date. 3 predicted ovulation on the 21; 2 on the 19 and 1 on the 24th (glow app). 
Now tell me can these Apps be trusted if I don't check my opk and temperature daily.

Answer

I would just assume your fertile window is from the 18th to the 25th just to be safe!

Answer

The more data you put in each day the better they can predict. Some apps will change their predicted date as you enter data. That happened to me. Both my fertility apps were off on my ovulation window but as I entered data each day, they now both have the same time frame. Except this month. The ovulation window is the same but projected period is off bc I ovulated late this month so not sure when AF is actually due now.
