Not worth it
Pay $100+ and you can get same results from your iPhone EKG app . Thing is Kardia will not tell you anything else if everything is normal because they are afraid of getting sued by a EKG result that could be debated by a professional Cardiologist. So I felt im not getting a true result just when everything is ok. On top of that they want to sell a $100 a year upgrade that still almos do the same.. what a rip off..
