Does this look like the app is correct?

A positive opk is when the test line is the same or darker as control line ……… It took me a while to get used to then as well 🙃

Make sure you take the pic in the same lighting, also I find using Premom tab (you can change from the top) gives more accurate reading.

@Sarah thank you! I'll try that tab instead.

Also, test with second morning urine - around 12pm or so. And start testing twice a day around your predicted ovulation time.
