KardiaMobile 1-Lead medical grade EKG plus 1 month KardiaCare | Displays EKG and heart rate on smartphone, no subscription needed | FSA/HSA eligible

I have both the KardiaMobile (Single-Lead) and KardiaMobile 6L (6-Lead). I keep the 6L at home and the KardiaMobile in my desk at work. Both devices give me the same nature of results; I can't tell whether the 6L is more accurate or more sensitive, they both seem to detect the same kinds of irrythmias. The KardiaMobile is easy to use at work, it just takes a few seconds, using two fingers, at your desk. The KardiaMobile came with a felt carrying case with magnetic closure, included in the box. At first I didn't quite understand how the KardiaMobile works, it doesn't use bluetooth it uses some sort of high frequency audio to communicate with your cellphone app. So your cellphone has to be nearby and the microphone can't be hidden from the KardiaMobile, they have to be fairly close to each other and sort of pointing at each other, then they can communicate just fine. I find the real-time results so useful to understand what's going on. This is so much more valuable than an annual check-up or a one-day Holter Test.

Easy to set up. Good to have a visual of EKG and to know it can be shared. Gives a sense of security.
