A smart fishing rod device that fits on the tip of any fishing rod. The line passes through the device, and the device senses tension on the line. A processor in the device is configured to interpret increases in tension as the presence of fish. The device can signal wirelessly to a smart device that there is a fish present. The device can also have one or more LEDs that flashes when a fish is present. The smart device can run an application (APP) that displays or signals the presence of a fish on one or more rods equipped with the device.
