Preppy: Sex & Health
PrEP, DoxyPEP & Prevention
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 & DoxyPEP
PrEP (Pre-Exposure Prophylaxis) helps you proactively protect yourself against HIV. By taking PrEP daily or on-demand, you can effectively prevent infection. DoxyPEP works similarly but is taken after sex to reduce the risk of bacterial infections such as syphilis or chlamydia. Consult your medical professional to find out which regimen best fits your lifestyle.
Preppy supports you with both methods, allowing you to focus fully on living your life.

Hi Preppy Team,First of all, thank you for building such a helpful tool for sexual health management. I really enjoy using the app to track my PrEP and testing schedule.I’m writing to suggest an improvement for the Sexual Partners section. It would be incredibly helpful if we could add a photo when creating or editing a partner’s profile. Having a visual reference would make it much easier to organize and identify entries at a glance, especially when reviewing history later.I hope you’ll consider adding this in a future update!
Developer Response Hey, thanks for the suggestion! With out latest update (v2.6) it is now finally possible to add up to 11 images for partners, so you never forget a face or anything else.I hope you like the update. Thanks for using Preppy and stay safe!

Developer Response Thanks for the feedback! Great suggestion to add DoxyPep as a feature, will put it on the list. Apple Health currently doesn't support an integration for medication, but it'll be implemented if it becomes available. Stay healthy!
