DK Swing On

The Diamond Kinetics Swing Collection (aka "DK Swing On") app is intended for use with the Diamond Kinetics SwingTracker bat sensor and Marucci Smart Bat to collect swing data for previously established user groups. It pairs with the sensor via Bluetooth Low Energy and allows users to log into an existing group to fetch their players' data and add additional swings. Swings can be collected while the iOS device is offline, but it eventually needs to connect to the Internet to sync those swings to the server. The app provides no means to view past swings or perform any user administration.
