Your Apple Watch measures how repeatable your dart throw is
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.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
