Green 19 is a lifestyle application designed specifically for golf tournaments, replacing traditional scorecards with a real-time tracking system. Participants can easily record their scores after each hole, receiving immediate updates on their rankings. The app features an aerial view of the current hole, providing insights into obstacles, while its GPS functionality measures the distance to the green. Additionally, an augmented reality radar helps identify the green, even when obstructed.

The app also caters to event sponsors, allowing them to display their logos to users at strategic moments. A spectator mode enables volunteers to check rankings and capture photos during the event. Organizers can utilize the Green 19 management platform to communicate with participants, and a leaderboard showcases the final rankings and photos taken throughout the tournament.
