It is very easy to use: Basically, you begin by answering some simple questions about yourself, your sex partner and the specific details of your sexual encounter. Once the App has all the details, it spits out a highly detailed report that shows your chances of getting an STI and/or STD. So you can evaluate the risk of STD transmission.The app works by applying powerful scientific methodology to analyze the details of your sexual encounter. It can tell you your sexual risk for Herpes (HSV1, HSV2), HIV, Chlamydia, Gonorrhea, Syphilis and HPV (which causes genital warts and cervical cancer). The entire App is based only on published, peer-reviewed scientific articles and data that come from respected researchers and universities (see our website).When you use STD Risk Calculator to do an assessment, you fill in all the information you know. For example, sometimes you know if your partner has an infection, but sometimes not. When details are not known, the App fills in the blanks by making educated guesses. For some sexually-transmitted infections (STIs), rather specific information must be known to provide an accurate assessment of risk. So additional questions are asked as needed and complex, research-informed metrics are performed.The App provides you with a detailed report that summarizes your sexual encounter and shows you your partner's probability of having a particular sexually transmitted infection. In addition to this, you can see the risk figures that show whether you picked up any of your partner’s infections. This information is presented as easy-to-read visual graphs. Finally, a list of risk factors is identified and presented. These risk factors may help you improve your sexual health by making smarter choices. It works great if you had a one night stand and what to see what your risk level is.
