Web App / PWA
PrEP Trackr
A privacy-first health tracking PWA for people on PrEP — logs doses, monitors protection status, and manages testing schedules from any phone browser.
Overview
PrEP Trackr is a free, private web application built for people taking PrEP (Pre-Exposure Prophylaxis) — a daily medication that significantly reduces HIV transmission risk. The app needed to handle sensitive health data with care, work seamlessly on mobile without requiring an app store download, and present complex medication adherence information in a way that felt clear and calm.
