Checkout 501 Trainer

Master checkout maths. Quiz drills, timed speed rounds, and live in-game finishes. Teaching you to get faster and more confident with every leg.

Every darts player knows the moment - you're stood at the oche, you need a finish, and your brain goes blank. Checkout is built to fix that.

Quiz Mode Drill checkout combinations at your own pace. Choose multiple choice or pick your darts directly, with the full calculation shown if you want to see the working.

Speed Mode Ten questions, one timer. Built for players who want to think faster under pressure, not just know the answers.

Live Mode Playing a real leg? Enter your current score and Checkout tells you exactly what you need to finish from there.

Checkout also tracks your progress over time, so you can see which finishes you've nailed and which ones still need work.

One app, built for one job: knowing your outs cold.
