How consistent is your throw?
Every session gets a consistency score from 0 to 100. It measures how repeatable your motion is, not where your darts landed.
Start a session
Wear your Apple Watch on your throwing arm and tap Start.
Coming soon for iPhone and Apple Watch

Coach
Your backswing was very repeatable today. The biggest variation happened in your follow-through towards the end of the session. For your next 20 throws, focus on the same relaxed forward motion after release.

Your throw stays yours. Motion data and analysis never leave your devices. No account, no cloud, no tracking.
Works offline
Practice in the basement or at the club. ThrowKit never needs an internet connection.
Built for Apple Watch
Made with Core Motion, SwiftUI and Apple Intelligence. It feels right at home on your wrist and your iPhone.
Questions
Which Apple Watch do I need?
Any Apple Watch running the current watchOS, paired with an iPhone on the current iOS. Wear it on your throwing arm.
Does ThrowKit know where my dart landed?
No. ThrowKit measures the motion of your arm, not the board. Your consistency score describes how repeatable your throw is, not your skill or your average.
Do I need an account?
No. There is nothing to sign up for. Your data lives on your iPhone and Apple Watch.
Is it free?
ThrowKit will be free to use with a generous weekly limit. A Pro subscription unlocks unlimited throws, your Throw Profile, long-term trends and the Coach.
Will it work with Autodarts or Scolia?
Not at launch. ThrowKit is built so that autoscoring systems can be connected later.
