Do you enjoy playing '01 darts but struggle with the math involved with chalking your score? Me too! So, I created this simple app so I could practice the math occasionally throughout the day. It has made a huge difference in the speed with which I can mentally calculate my score, which has made dart league night all the more enjoyable.
To use the app, click the blue "Click to start" button at the top. It will randomly generate scores for each of your three darts (it's actually not random, it uses an algorithm to make the scores a little more realistic).
Then, enter your total for the throw in the first box and click "Submit". If you're correct, a new box will appear, in which you enter your new total score (which you calculate by subtracting your total for the throw from above from the provided "Initial score".
