Smile ovulation test versus two line ovulation test?

Hi ladies!

Need some opinions out here!

I’ve been using the two line ovulation test and can always track my ovulation this way we’ll.

But I know a lot of people use the clear blue smile face <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a>.

What’s the difference between the two? Should I maybe try the smile one for better chances ttc?
