What makes you say that? This is exactly the sort of scenario where punting interpretation off to a simple algorithm is probably more accurate than leaving it up to untrained humans.
I read a comment in a reddit thread and they said the "pro-tip" was to take a picture of the pregnancy test and up the contrast to be able to better interpret results.
So a less wasteful idea would be a companion app to help with that process vs. more electronics in a landfill. (Although obvious privacy implications exist).
That could happen with any two tests. That second test is really faint. At first I thought "Ok, so they're both negative, so what?"
Not to mention, false negatives are far more common than false positives. If you have a false positive, then there's typically some odd health concern with the person.
