Summary

A budget fitness tracker with a 1.47-inch AMOLED screen, 123 sport modes and 5 ATM water resistance, aimed at casual wear and swimming rather than medical accuracy.

Strengths

  • Light and comfortable enough for all-day and overnight wear.
  • The AMOLED display is bright and easy to read.
  • 5 ATM water resistance covers swimming and showers.
  • Blood oxygen readings came within 2% of a pulse oximeter in one test.
  • Magnetic charging is simple to use.

Weaknesses

  • Blood pressure readings run 10-15 points above a cuff monitor and are estimates only.
  • Sleep tracking misses awake periods and can log sleep while you are up.
  • The touchscreen is sensitive enough that water droplets and clothing trigger inputs.
  • The Keep Health app rates 3.4-star on the App Store and can lag.
  • No built-in GPS, so outdoor routes need a phone.
  • No auto workout detection.

Tracking and accuracy

The 24/7 heart rate and SpO2 tracking are the strongest parts of the package. In testing of a closely related Zeacool tracker, blood oxygen readings stayed within 2% of a fingertip pulse oximeter across 15 sessions, and heart rate was described as reasonably accurate during steady exercise. That test covered the 1.10-inch, 25-mode variant, not the 1.47-inch FT55, so treat the numbers as directional.

Blood pressure is the weak spot. Sleep tracking is a mixed bag: it misses awake periods and sometimes logs sleep when you were up. Body temperature tracking is also included.

Battery and water resistance

Zeacool rates the battery at 10-14 days of regular use and 30-day standby. One test measured 12 days with 24/7 heart rate on, another said it easily lasts a full week, and app users report shorter runs of 5-7 days and 7-8 days with heavier use. Charging is magnetic. The sensitive touchscreen is the one annoyance in water: droplets and clothing can register as taps.

The Keep Health app

The tracker pairs with the free Keep Health app. One user says heart rate is logged every 15 minutes with no way to force a more frequent reading. Nothing here needs a subscription.

Which model this is

This page covers the FT55 in Bordeaux, sold with a 1.47-inch display and 123 sport modes. The ASIN is B0HKV6N1MG.

Don’t confuse the FT55 with the C60, which is a separate model.

Is it worth it?

Below about $25 it is good value for a casual tracker: AMOLED screen, 5 ATM water resistance, 24/7 heart rate and SpO2, and two weeks of battery. Abunda lists a Zeacool tracker at $25.99 (2026), and review sites put it under $25 to just under $26. Above $35 the case weakens, because established alternatives from Fitbit and Samsung bring more mature apps and better-tested accuracy. The value is in the hardware, not medical-grade measurement.
