Can we use my smartwatch without smartphone?
It really depends on the kind of smartwatch you have.
If it’s a semi-smartwatch, the kind that has to be paired to a phone for you to do anything with it beyond telling the time, then it will have to be paired to your phone no matter what. On the other hand, if it’s a full smartwatch, or at least a specialty watch, you should be able to use it without your phone.
If you’re using a Samsung Watch or Apple Watch, there’s probably not much you can do with it if your smartphone isn’t nearby. These watches are designed to be one half of a compact system. From the ability to read texts and make calls to the functionality of such things as fitness apps and heartrate monitors, these watches need a smartphone paired to them for any major use.
On the other hand, there are smartwatches built by independent manufacturers that can work on their own. They’re usually built to be able to work with Android or iOS, but they also have their own native apps that help you do stuff like track fitness, monitor your heart rate and sleep patterns, and also schedule stuff. When your smartphone is around, you can just sync them with your phone so it’s up to date.
And then there are specialty watches. Hiking watches like the Garmin Epix, for example, have accurate GPS and weather forecasting, as well as altimeters to read the altitude and hygrometers to check humidity. You can do all that without having a smartphone around. Diving watches like the Garmin Descent MK1 can be hooked up to oxygen regulators to track how much oxygen you have left or they can be used to measure how deep underwater you are. And of course there are also fitness watches like different Fitbit models.
As you can see, it ultimately depends on the specific smartwatch you have.
