Third-party reviews

What we like about ArmFit Deep Zeero

  • 15 days of battery life means very few charges.
  • Distance, pace and sleep are all tracked.
  • Sleep reports help you review your nights.
  • Continuous SpO₂ monitoring tracks blood oxygen over time.
  • A multi-sport mode covers different workouts.
  • The 10 m depth rating covers showers and a swim.

What we don't like about ArmFit Deep Zeero

  • At 90 g it is heavy for a band worn all night.
  • The 1 ATM rating is low, so it is not built for diving.
  • There is no GPS, which limits outdoor tracking.
  • The companion app is required before it can be used.

Verdict

Fifteen days of battery life is the first thing that stands out about the ArmFit Deep Zeero. You can go about two weeks without reaching for the charger. It tracks distance, pace and sleep, and it provides sleep reports. The continuous SpO₂ sensor keeps an eye on blood oxygen over time, which is not something every wristband does. A multi-sport mode covers many workouts, and the touchscreen makes switching between them quick. The trade-off is weight. At 90 g it is heavy for a band you wear all night, and you will notice it in bed. It has no GPS, which matters on a hike. It suits someone who wants a wristband that goes days between charges and gives a steady view of sleep and training.
