What we like about Haylou LS01

  • Exceptional value for money, often priced around $20.
  • Impressive battery life, lasting between 7 to 14 days on a single charge.
  • Lightweight and comfortable design, weighing only 34g for all-day wear.
  • IP68 water and dust resistance, making it safe for handwashing and rain.
  • Clear 1.3-inch LCD display with adequate brightness for outdoor use.
  • Reliable 'raise to wake' feature and smooth user interface navigation.

What we don't like about Haylou LS01

  • No built-in GPS; requires a tethered smartphone for route tracking.
  • The companion Haylou Sport app is often described as basic, unintuitive, or buggy.
  • Limited smart features: cannot reply to messages or answer calls directly from the watch.
  • Notification syncing issues, such as deleted messages on the watch not syncing to the phone.
  • Lack of advanced health metrics like SpO2 or stress tracking found in newer budget models.
  • Occasional software stability issues, including rare hard freezes or find-my-phone glitches.

Verdict

The Haylou LS01 is an entry-level smartwatch featuring a 1.3-inch TFT LCD square touch display with a 240x240 pixel resolution and a lightweight 34g build. It is equipped with an IP68 waterproof rating, a 210mAh battery offering up to 14 days of life, and essential sensors including a dynamic optical heart rate monitor and accelerometer. Main characteristics include support for 9 sports modes—such as jogging, cycling, and yoga—alongside comprehensive sleep management and real-time app notifications. Its primary pros are its exceptional affordability, comfortable design, and reliable battery performance. However, notable cons include the lack of built-in GPS (requiring a smartphone connection for route tracking), no support for replying to messages directly from the wrist, and an application interface that users sometimes find basic or buggy.
