Overview
BIGGERFIVE builds the BW02 as a kids and teen smart watch with a touchscreen, a silicone band and games alongside the usual step and sleep tracking. Location comes from a paired phone.
Puzzle games, a vibrating alarm and a timer make it feel more like a toy-style watch than a sport tracker. The limitation is the missing runtime and a water rating that undercuts the waterproof label.
Who it's for
School days, play and basic step and sleep tracking are the setting, with a parent's phone supplying GPS. Adults, swimmers and anyone wanting detailed training data should look at a model built for them.
Pros and cons
- Games and a timer built in
- Charging cable and manual included
- Long warranty term
- Heart rate and sleep tracking
- Battery life not listed
- Shallow depth rating despite waterproof label
- GPS needs the phone
- Only one sensor metric listed
Performance notes
Step counts come from motion sensing and heart rate from an optical sensor on the skin, so readings are estimates and shift with fit. Games and screen time drain the cell faster, and a small wrist may need the band tightened for steady readings.
