Ovulation test

Hey guys all my tests have never come out as dark as the control line but this one is the darkest I’ve had would you say this is positive? Also my app said I ovulated a few days before I took this test gutted I didn’t test then I took this test 2 days after the app said it was my ovulation day would you go by the test or the app as I’m confused on how to work how many dpo I am thank you xx
