Apple tells us there's an app for everything - and soon, there'll even be one to test yourself for STDs. Doctors and researchers in the UK are developing an app that would allow people to test themselves for STDs at home. Users would purchase testing chips from pharmacies, place a drop of urine or saliva on the chip and insert it into their phones. In a few minutes, they'd receive their diagnosis. The researchers are spending $6 million on the technology, hoping it will inspire more people to get tested for STDs regularly.
