Blue Feather Digital GmbH

Blue Feather Digital GmbH is a Swiss software company that operates StarFlash, described as a real-time IoT sensor search engine. The company pairs its software platform with consumer-facing hardware: the Star Flash Storm S, a smart shoe that measures how the wearer moves and meets the ground. Rather than inferring motion from a wrist-worn device, Storm S places sensing directly beneath the foot, combining a 9-axis IMU, a barometric altimeter and a plantar pressure matrix through sensor fusion. The result is a stream of live readings — pace, speed, elevation, climb rate, impact force, direction, temperature and left/right pressure — surfaced through the Star Flash app. The product is positioned around making movement visible. Accelerometers and gyroscopes track acceleration, roll, pitch and yaw across each stride; the pressure matrix maps center of pressure, ground contact and load distribution; sensor fusion combines motion and compass data while each foot strike helps correct drift; and the barometric altimeter measures stairs, ascent, descent and vertical movement over time. The shoe is offered in six colors and is presented as suitable for environments from city streets to steep trails. An interactive 3D viewer lets users rotate, pinch and zoom to inspect the product, and the company also promotes replaceable Smart Foot Pads as a consumable intelligence layer. Blue Feather Digital GmbH is a privately held company; no parent, owner, founding year, founder or executive names are established by the available evidence. Its public commercial identity is built around the StarFlash brand and the Storm S hardware-plus-app ecosystem, with starflash.ai serving as the primary web presence.

Blue Feather Digital GmbH is a Swiss software company whose documented activity centers on StarFlash, a real-time IoT sensor search engine. The company's public-facing commercial identity combines that software platform with a hardware product line: the Star Flash Storm S smart shoe, marketed through starflash.ai. The Storm S represents a distinct approach to wearable sensing. Instead of relying on a wrist-worn device to estimate movement, the shoe measures every contact beneath the feet. Its sensing stack combines a 9-axis IMU, a barometric altimeter and a plantar pressure matrix, fused to map how each foot moves and meets the ground. The system tracks 3D foot motion through accelerometers and gyroscopes that record acceleration, roll, pitch and yaw across each stride; pressure and force through a matrix that maps center of pressure, ground contact and load distribution; speed and direction through sensor fusion that combines motion and compass data while each foot strike helps correct drift; and climb and elevation through a barometric altimeter that measures stairs, ascent, descent and vertical movement over time. Live readings are surfaced through the Star Flash app, which lets users see current pace, speed, elevation, climb rate, impact force, direction, temperature and left/right pressure, compare sessions and understand how movement changes across terrain. The shoe is offered in six colors and is presented as suitable for environments ranging from city streets to steep trails. An interactive 3D viewer on the website allows visitors to rotate, pinch and zoom to inspect the product, and the company promotes replaceable Smart Foot Pads as a consumable intelligence layer. Beyond these product and platform facts, the available evidence does not establish Blue Feather Digital GmbH's founding year, founders, headquarters city, ownership structure or leadership. The company is presented as a private Swiss software business, and its brand equity is tied to the StarFlash name and the Storm S ecosystem.
