Whats most accurate ?

Question

So I have a few apps and they all say different ovulation days. I'm like clockwork same days and same amount of days each month but this app says I ovulated the 28 and my other apps say yesterday the first. We bd on both days but I'm curious who has other apps and is glow the most accurate for ovulation tracking or are the other apps such as ovia ?

Answer

I have both apps and the longer I've had both, and the more info I've logged, they both have the same ovulation date month to month. The only difference I've noticed is the start of my period shows a day later on ovia than I does on glow

Whats most accurate ?
