Preppy: Sex & Health
PrEP, HIV (ART), DoxyPEP & STI
Free
** App of the Day on World AIDS Day 2022, 2024, and 2025 **
Take control of your sexual health with Preppy. Developed with expertise from medicine, psychology, and health education, Preppy offers you a safe and discreet home for everything important to your intimate well-being.
PrEP
PrEP (Pre-Exposure Prophylaxis) helps you proactively protect yourself against HIV. By taking PrEP daily or on-demand, you can effectively prevent infection.
DoxyPEP
DoxyPEP is taken after sex to reduce the risk of bacterial infections such as syphilis or chlamydia.
HIV Status & ART
Set your HIV status in Preppy and track ART (Antiretroviral Therapy) if you’re living with HIV. Daily intake logging and reminders help you stay on schedule.
Preppy supports you with all three, so you can focus fully on living your life.
