What we don't like about Haylou Gst

  • Lacks built-in GPS, relying on a connected smartphone for route tracking
  • Fitness metrics like step counting can be inconsistent or inaccurate
  • Does not support answering calls directly (no speaker/microphone)
  • The companion Haylou Fun app can feel barebones or have connectivity issues

Verdict

The Haylou GST is a budget-friendly smartwatch featuring a 1.69-inch TFT square touch display with a 240x280 resolution and 2.5D curved glass. It is built with a zinc alloy frame and a plastic back, weighing approximately 42g and carrying an IP68 dustproof and waterproof rating. Key technical capabilities include 24-hour heart rate monitoring, SpO2 (blood oxygen) tracking, sleep analysis, and 12 dedicated workout modes. Its 220mAh battery offers a typical life of about 9 days, extending up to 20 days in basic mode. Main pros include its lightweight and comfortable design, sharp sunlight-readable display, and comprehensive health sensors for its price point. However, notable cons include the lack of a built-in GPS, speaker, and microphone, meaning it does not support standalone location tracking or direct Bluetooth calling.
