Definitely a competitor. Advantage of iRhythm would be the leadless technology. BEAT devices all require leads applied to the chest leading to wires attached to a sensor worn around the neck. Cumbersome for sure compared to the Zio device by iRhythm which needs none of that. Interestingly, the Zio uses Splunk tech (I have no idea how) which I believe has been discussed on this board as well.
Youtube video link here if you desire to see the device and how it’s placed. https://youtu.be/uu5UDpE_4qo
