Flo

Both flo and Ovia had my ovulation dates around 5 days out x

I have! It did take a good while for me when I was tracking it on that so I done it a day before it said my ovulation was and then right up until the actual highest ovulation day and it finally worked 😂 can be frustrating so don’t get to caught up on it. I also found I needed to be tracking my period for a good while for it to be reliable

Flo was accurate for me but I wouldn’t just go off it. Look for other signs of fertility and or cross reference with ovulation tests.
