‘Catch My Pain’ is an app that acts as a pain diary. I’ve found it to be incredibly useful in tracking possible cycles and remembering important days of pain and possible causes. I’m finding it to be an invaluable resource. You can rate your pain, do color coded mapping on a human form to mark out where your pain is and its severity, detail specific things going on, and they’ve also included a way now to send that information to your physician(s) if you so choose.
