Existing apps may be a reasonable conversational shortcut for people who otherwise would just plow right through without talking about these things at all, but I have my doubts. I'm particularly bothered by apps that say things like simply "good to go." Any results less detailed than the ones provided by this app - which list not only test results, but the date the tests were done and which tests were actually performed - are basically useless. For that matter, even results like those, which look comprehensive, don't mean a potential partner has been tested for everything. Screening for genital herpes, for example, isn't listed on that screen, because it is rarely done unless someone has symptoms. That's one reason why it is so often passed from partner to partner without anyone realizing what's going on.
