I thought so too, but the paper version apparently has a ridiculously high (user) error rate. When the failure mode is an extra human it might be a net win.
While may will buy a pregnancy to check for unwanted pregnancies, there's also many who use them to check for wanted pregnancies, so perhaps only to not wanting to be pregnant should use the electronic tests?
I feel like there's a better option, it has to be possible to improve the paper version, without adding a battery, LCD and a CPU.
Oh this is a good idea. Calibrate for the phone / camera version and test used and just let your phone read the test and run a little timer.

Would be a good add in for ovulation tracking apps.
Also, if you are a pregnancy test manufacturer, maybe you release this app so you can see what other tests people use; educate them on the error rates of competitors; and offer 1 click purchase of your products.
I was going to comment “oh for f* sake not another app”, but that actually pretty clever. Just add a QR code to the test and the text: having trouble reading our test, download our app”.
