According to those who’ve used its syncing options, it works relatively well in that regard, although it’s also worth noting that Motorola have received some criticism in this regard from a certain circle of reviewers.
The problem, according to them, is that users shouldn’t treat this device as its own separate thing, and should instead use it with a smartphone in order to get the most out of it. This can be a bit problematic for some, especially those who’re buying a smartwatch so they can avoid carrying a phone around all the time, but it’s the way things work right now.
Plus, the paired phone doesn’t necessarily have to be on the user at all times, which does make the situation more convenient. In the future, when hardware gets even more powerful, we might see smartwatches that are entirely independent, but for now even the Moto 360 is a great deal, especially at its current new price.
