Once I learned I had Atrial Fibrillation (AF) I wrote an app that pulls my heart rate data from a normal consumer Polar chestband, then pushes it to a server where I can see it on Grafana. It was incredibly useful, and helped me learn what the different feelings in my heart mean. I know exactly when I am in AF and when I am not. There seems to be a huge gap for this kind of consumer grade offering, probably because the medical fraternity is extremely conservative about any technology, even though the alternative is ... nothing.
