I am personally liking CTP more. FF is telling me that the best time for me to test is the 17th...5 days after my missed period. I am just not really liking their dates. I also find their charting not very user-friendly. It could just be me though.

When i tried both gave me the same Ovulation date.

Also, they both said I O'Douls on cycle day 13 until,I entered today's temp. Than FF changed to cd15. Which makes me think FF is more accurate
