NailNick Tracker-Concise

This is a concise tool for recording nail spines. Whenever you notice a nail barb, you can record whether it appears on your left or right hand, which finger it is on, the size of the barb, and a note. You can also attach a photo for future reference. Count the frequency of occurrence of each finger to help you identify the most frequently pricked finger at a glance, without collecting any privacy, just as a recording application.
