I’ve been using Flo for a couple years now and it hasn’t all the way failed to predict my start dates; a few times it’s predicted earlier than actually but most accurate. I am new to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and I’ve entered previous periods and my fertile window is very different than Flo’s. In your experience, had this app been pretty reliable for you? Both period and fertile window-wise? Thanks!!!
