A mobile application was developed for Tac-Alert’s wearable device to provide a simple and effective user interface. The application provides enhanced situational awareness for tactical users by managing detection data, radiation-safety levels, and alerts. Location and status information of nearby users will be implemented in the future. The app wirelessly communicates with the device via the Bluetooth low energy protocol and runs on both Android and iOS for maximum compatibility. The app is both modular and configurable so it can scale properly.
