Filter Quit-Smoking App

Customer app and admin panel for a quit-smoking planner

Filter helps people plan to quit smoking. I developed both its customer app and its admin panel. The customer app covers onboarding, a dashboard, health improvement tracking, audio books, subscriptions and gift cards, and runs as a PWA that is also packaged for Android.
