Overview
Not a GPS watch, the Samsung SM-R390 is a pink activity tracker with an aluminum case, a silicone band and both touch and button control. An AMOLED screen shows the readouts, and sleep monitoring is among the supported apps.
A bright AMOLED screen and a decent water rating suit daily wear and light workouts. The limitation is the Android-only phone requirement and the missing battery life figure.
Who it's for
Everyday wear and light fitness logging with a recent Android phone are the setting. Anyone on iOS, or who needs GPS routes or a stated runtime, should look at a model that lists them.
Pros and cons
- Bright AMOLED screen
- Water resistance rating listed
- Touch and button control
- Band and charging cable included
- Android phones only
- Battery life not listed
- No GPS in the listing
- Metrics list is minimal
Performance notes
A bright AMOLED panel is easy to read outdoors but draws more power as brightness rises, so battery life depends on screen settings. Without confirmed GPS, distance is estimated from motion sensing rather than a satellite fix.
