This document describes the APPlied Club, which teaches high school students mobile app development skills. It started at one school with 10 students and created one app and one game. It has since expanded to include more clubs, meetups, game jams, and opportunities for students to gain work experience and jobs in app development. The club aims to expand further by creating game kits and a STEM core curriculum for mobile app and game development. It discusses successes, challenges, and goals to continue growing the program.
