Counting the Minimum Mandatory Play Rule (MPR) for Pop Warner teams is hard work with a pen and paper. Even trying to carry a laptop is hard. MPR is something that would be great on a tablet/iPad. PlayCounter by SCRBRD is a great option to keep track of plays with accuracy and even a little bit of fun. OK it’s not fun but you do get to be on the sidelines and use an iPad, not many people get to do that.
