Use it all the time. Configure field dimensions based on available area. Change outer dimensions that you have while keeping the field within USSF age guidelines. Set penalty area and goal area to regulation sizes and field dimensions are shown in easy to follow diagram. A^2+B^2=C^2 and you have the outside box. Measure your marks along goal line for the inside areas. Square them up and you’re field is played out ready to paint. Use this 100 times a year setting up tournament fields. Make adjustments due to poor grass or damaged goal boxes and new design is done in seconds. Best soccer tool on my phone! I also built a reference library of European fields to compare dimensions for those debates over who has larger fields and most width to play on.

This is a very handy app if you are involved in building, measuring and lining soccer fields. Easy to change field sizes and you can save numerous configurations. Measurements are spot on, well done!

The stool doesn’t do anything, other than save measurements for you. You can just take a picture of the measurements, and that would have the same efficiency as this tool.
