Description
ThrowKit turns the Apple Watch on your throwing arm into a darts sensor. Throw as usual; your iPhone then shows how repeatable your motion was, with a consistency score and five measures for every throw. Guided drills on the Watch. No account, no ads.

Could you build this?
Partial Building standard iOS and watchOS companion apps is straightforward, but capturing, segmenting, and mathematically analyzing high-frequency CoreMotion sensor data to quantify human arm repeatability is mathematically non-trivial.
What it would actually take: The app requires high-frequency accelerometer and gyroscope data collection via watchOS CoreMotion APIs, filtering (Kalman or Butterworth filters), and dynamic time warping (DTW) algorithms to align and compare irregular throwing motion phases. Extracting reliable biomechanical metrics requires signal processing and sensor fusion expertise to distinguish actual dart throws from incidental wrist movements.
