Best app to use to track ovulation and best ovulation tests to use

Hi all, I was lucky enough to become pregnant with my first very quickly. This time it’s taking a bit longer. I’ve been using ovulation tests but they don’t seem to be accurate as apparently I’m ovulating every day. What apps/strips do you use? Also, is there an app you can use to find your most fertile days? I do use flo (which is what I used with baby number 1) but things don’t seems to be adding up this time. Any advice is much appreciated!
