This project instant solves the pointless water sort puzzle. The button works for images like the example on the right. For any other version of the game, image recognition is unimplemented. The python version is also available.

As the water sort app has updated substantially since December 2020, image recognition won't work. Thus here is a manual input field. Give each color a unique letter. Next input the colors for each vial from bottom to top. Separate each vial by |. The default input below matches the example image.
