Sam Hayman presented on app icon design. Effective app icons are simple yet engaging designs that clearly suggest what the app is through imagery. Icons need to stand out with techniques like contrasting colors, borders, and bright colors to draw the eye. First Impact's app icon target audience is young people aged 14-30, focusing on males 14-20. Several draft icon designs were created and improved through peer feedback before selecting a final icon design incorporating colors resembling the night sky.
