We just got this device 2 weeks ago. My husband and I are RNs & already use other home health devices: glucometer, sphygmomanometer, temporal thermometer, continuous glucose monitor, Apple Watch activity tracker, etc. One day last month I was having an irregular pulse. Since we participated in the Apple Heart Study and were familiar with EKG functions using the Apple device, my geeky 🤓 husband researched EKG devices that’d work with our Apple products. He first looked at the KardiaMobile but was put off by the idea of a paid subscription to their service. Further research brought us to the SonoHealth device & for a substantial discount. We ordered it and have found it helpful for verifying some concerns we’ll need to address with our health provider. It provides 3 different leads, there’s no additional expense and the support offered is remarkable. This is an elegant device and a nice addition to our ability to provide home health insights to neighbors & friends.
