Centor score for strep play online

This is an app to evaluate the necessity of treating a throat infection with antibiotics. The score is defined in https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1228750/pdf/cmaj_158_1_75.pdf - The creator of this app has no affiliation with the study group defining the score. I just found it convenient to have it on my phone as a reminder.
