Last refreshed Aug 4, 2026 · Based on the Amazon listing and published specifications, not hands-on testing.
A feature-heavy tracker listed for youth and adults alike, with Bluetooth calls and a large screen. GPS comes from the phone and the water rating is shallow, so it suits daily wear more than swimming.

Overview
Counting steps, calories and distance, the FITVII HM57 is an activity tracker with a touchscreen, side buttons and a band of thermoplastic polyurethane. Calls and notifications arrive from the phone over Bluetooth.
A big screen, calls from the wrist and a week of battery cover the everyday basics. The limitation is reliance on the phone for GPS and a water depth rating that is barely a dunk.
Who it's for
Daily steps, reminders and phone alerts for school or the office are the setting. Anyone who swims, rides long routes or needs location data without carrying a phone should look at a model with its own GPS.
Pros and cons
- Large screen for a tracker
- Bluetooth calling listed
- Sedentary reminder included
- Long warranty term
- GPS depends on the phone
- Shallow water depth rating
- Short metrics list
- Controller type entry says iOS
Performance notes
Step and calorie counts come from motion sensing, so they are estimates that drift with arm movement. Calls run over a Bluetooth link to the phone, which has to stay within range. Battery life falls with screen brightness and the number of alerts.
