Additionally, the developers have cut corners by not integrating the app with HealthKit. As a result, Apple Health only tracks steps, and any other data has to be added manually, which is far from ideal. I’m really disappointed because the watch itself has reasonably good sensors. We tested the ET570 in our lab, and it proved to be more accurate than Apple Watches, Samsung, and Garmin models.
If the app worked, this watch would be an excellent purchase. But as it stands, it’s unusable since it doesn’t store data on the phone for more than a few days, and there seems to be no urgency from the developers to fix these issues. They don’t even respond to customer inquiries.
