Best of the Bunch!

After trying several heart rate measuring apps, Cardiograph clearly stands out as the best of the bunch. It has proven to be more accurate and responsive than the others I’ve tried. It’s not difficult to get a reading as other apps have been. They don’t try to sell you other services. My Doctor and I compared it when I was in his office and its reading were right on the money!
