A small purple fitness band with a 0.96-inch screen, a built-in USB plug for cable-free charging, 11 exercise modes, heart rate, blood pressure and sleep tracking, and up to a week per charge.
The ZURURU Y39 solves the most common reason a fitness band ends up in a drawer: a lost charging cable. The tracker pops out of the strap, and one end is a USB plug, so it charges straight from a laptop, a wall adapter or a car port.
No proprietary clip, no magnetic cable to misplace. Detach the tracker from the band, plug it in, and one to two hours later it is full. A single charge gives up to a week of use.
Places a USB-plug band can charge:
The design keeps everything small. The tracker measures about 0.75 x 0.43 x 1.61 inches with a 0.96-inch colour screen, in a plastic case on a soft purple silicone band. Raise your wrist to wake it, or tap the touch button to cycle through steps, heart rate and time.
A little screen has trade-offs. Messages appear in short lines, and long texts are better opened on the phone. For a slim band with more room on the display, look at the 1.47-inch models in the alternatives, such as the Runlio T115.
When the USB end wears or gets dirty, clean the contacts with a dry cloth before assuming the battery has failed. The charging guide covers other plug types too.

The Y39 has 11 exercise modes, and it borrows the phone's GPS to go further than a plain step count. Start a walk or a run with the phone in your pocket, and the H Band app records pace, distance and a map of the route.
That route map is a strong motivator. Seeing the same loop drawn week after week, with the pace improving, turns a routine walk into visible progress.
How to use connected GPS well:
Outside workouts, the Y39 tracks steps, calories, distance and exercise time. At night it separates deep sleep, light sleep and awake time, and the H Band app turns those into daily and weekly charts.
Heart rate and blood pressure readings are in the mix too. Wrist-based blood pressure is an estimate, useful for spotting trends in your routine, not for diagnosis. If blood pressure is a medical concern, a cuff monitor is the right tool.
The guide to blood pressure and SpO2 readings explains why wrist figures drift and how to read them sensibly.
The Y39 runs on the H Band app. The band is listed for Android and iOS phones, and all setup, history and reminders live in the app.
Once linked, calls and messages buzz on the wrist. The band shows who is calling but does not answer; take the call on the phone.
The Y39 holds up to 20 alarms, a generous number for a small band. That makes it easy to build a routine around gentle vibrations instead of a loud phone alarm:
A period reminder handles cycle dates, and a find-my-phone button makes the phone ring when it is lost under a cushion.
IP68 handles hand washing, sweat and rain. Rinse the band after a workout, but leave it on the side for the pool and hot showers.
The Y39 is one of the smallest and simplest bands in the group. Its rivals mostly trade up the screen size or add blood-oxygen readings.
| Band | Screen | Stand-out extra | SpO2 |
|---|---|---|---|
| ZURURU Y39 | 0.96-inch | Built-in USB plug | Not listed |
| S5 Slim Fitness Tracker | 0.96-inch | Body temperature | Yes |
| FITVII HM08 | 1.47-inch | Jewellery-style slim design | Yes |
| MorePro Air2 | 1.57-inch | Silicone and nylon straps | Yes |
The S5 Slim keeps the same small screen size and adds blood oxygen and body temperature through the Runmefit app. The FITVII HM08 is a slim band with a larger 1.47-inch display. The MorePro Air2 comes with silicone and nylon straps and pairs with FitCloudPro.
What the Y39 offers in return is simplicity. A touch button, a handful of screens and a charger you cannot lose. That suits first-time users and anyone who found a bigger smartwatch fiddly. Older relatives often do well with a band like this: plug it into the same USB adapter as the phone each week, and it keeps counting steps and sleep with no menus to learn.
The Y39 fits best if:
Check before buying:
A small band that is always charged and always on the wrist beats a feature-packed watch that sits on the nightstand. For a first step tracker, the Y39 keeps the habit easy. Spare straps for small bands are covered in the strap guide.
Pop the tracker out of the band and plug its built-in USB end into any USB port. A full charge takes 1 to 2 hours and lasts up to a week.
H Band. It handles pairing, alerts, alarms, sleep charts and route maps recorded through the phone's GPS.
It uses connected GPS through your phone. Carry the phone during a workout and H Band records pace, distance and the route.
No. It shows who is calling and displays messages, but calls are answered on the phone.
Treat it as a trend estimate, not a medical reading. For health decisions, use a cuff blood pressure monitor.
