John Bindel, a skydiver and programmer, discusses his app called Funjumper, which provides skydivers with weather information, jump run planning, and community features. The app allows users to see the weather conditions, winds aloft, and jumpability for each hour of the day. It also shows who is going to the drop zone, allowing users to connect with potential jump partners. The app includes a feature called the drift box, which predicts the drift under canopy based on winds aloft data. John has plans to add features for drop zone managers to help them administrate their drop zones more effectively. The conversation covers various topics related to the app's features including load organizing, movement groups, jump plans, historical weather data, GPS tracking, anemometer integration, and video sharing. The app aims to provide a comprehensive tool for skydivers to enhance safety, communication, and organization at drop zones.
