This is GTH so its not their flagship device, I had a look on their site and they market it as a budget health tracking smartwatch. Which I feel it does well.

In regards to Arty, it seems reliable, I tested it during the week (office job, not as active, but i do exercise daily) and my scores were around 72-80 each time depending on the day. I had a really active long weekend and went on a hike etc so I tested it again and gave me a score of 90 on the Monday. I just did it now after 2 days back at the office and I got 73, 3 times in a row.

Personally I am not someone that tracks their exercise, and I have never owned a smartwatch. As we know this isn't FDA approved but I do feel that for those interested in health tracking, which would be the target customer, it provides a reading much more useful and a lot more reliable than what smartwatches currently offer.
