$55 UWatch UX Strapless Heart Rate Monitor Watch Syncs with iOS and Android Devices

Last time I checked about heart rate monitor, they required a chest strap to monitor ones heart rate, which I found cumbersome. It’s been while though, and I’ve now been informed that a low cost Bluetooth strapless heart rate monitor watch was available for $59.99 on GeekBuying.


This type of product should provide a much more accurate evaluation of your daily calories burn rate than typical fitness bands based on an accelerometer and gyro sensor, but I’m not quite sure how they compare to the old models with a chest strap.

Uwatch UX specifications and features:

  • SoC – Mediatek Aster MT2501 ARM7 processor @ 108 MHz (A lower end version of MT2502 used in LinkIt One Devkit)
  • System Memory – 32MB RAM

  • Heart rate monitor – Built-in photoelectric heart rate sensor
  • Other sensors – magnetometer, 3-axis gravity and acceleration sensor
  • Connectivity – Bluetooth 4.0 and NFC (for easy Bluetooth pairing)
  • Display – 1.44″ capacitive touch screen (128×128 resolution)
  • Mobile Synchronization with Android and iOS – Phonebook / Call log / SMS / Music / Time sync
  • Other functions:
    • Remote control phone camera( Not supported by iOS system)
    • Pedometer
    • Sleep monitor
    • Anti-lost / anti-theft –  When the phone is away form your Bluetooth distance of the watch, the watch will remind you, and you can also remotely find your phone by making it ring with the watch
    • Earphone talking and music playing
    • Compass, Stopwatch, Alarm…
  • Battery – 260mAh Li-polymer battery; 180 hours in standby mode; 4 hours of talk time.
  • Dimensions – 52.5x37x9.9mm

Uwatch_UX_Heart_Rate_Monitor_WatchTo synchronize with an Android phone, you can download Smart-Watch.apk or install SmartBlue from Google Play, while for iPhone or iPad you can install SmartBlue from the app store.


The watch ships with headphones, a USB charging cable, and a user’s manual. There’s a short demo video going through the user interface of the watch, but unfortunately they don’t really test the heart rate monitor function.

Beside GeekBuying, Uwatch UX is also sold on GearBest for $54.99, Amazon US for $89.50, and PandaWill for $64.99.

“4 hours of talk time”? :s

Pretty sure I saw a comparison of this kind of HRM with the chest strap kind, indicating they generally track pretty well. (It’s be nice if this could also take input from a BT &/ common HRM strap protocols though…)
