What can the G104 do on its own without a phone?

It shows the time, tracks steps and heart rate, and runs its watch faces and UI styles. Calls, notifications and app syncing need a Bluetooth link to your phone.

Does it make and take calls?

Yes. It supports Bluetooth calling, so you can answer and talk through the watch once it is paired with your phone.

Which app does it use?

It pairs with the Dafit app, where you set watch faces, check activity data and adjust settings.

How accurate is the heart-rate monitor?

It gives a general reading for everyday activity and workouts. It is not a medical device and is less reliable than chest straps or dedicated fitness watches during intense exercise.

Can I change the watch face?

Yes. You can customize the face and choose from 8 UI styles, so the look changes without a new watch.

Is it worth it over a brand-name fitness watch?

If you want calls, notifications and basic tracking on a big screen, it covers that. If you need accurate workout data or deep health metrics, a brand-name fitness watch is the better fit.
