Advanced iOS implementations take this a step further by predicting the storm’s trajectory. By analyzing the pattern of strikes over time, the software draws a vector—a line showing where the storm is heading. This allows users to determine if the storm is moving toward them or drifting south, providing crucial time to seek shelter.
A significant part of the "iThunder" ecosystem involves hardware accessories that pair with iOS devices. Several companies produce personal lightning detectors—small, handheld devices that connect via Bluetooth to an iPhone.
