Amazfit GTR 4 Review: A Big-Screen Smartwatch That Skips the Subscription
- Brand:
- Amazfit
- Ages:
- 13+ years
- Updated:

The verdict
The Amazfit GTR 4 delivers a genuinely nice AMOLED display, built-in GPS, and no-subscription health tracking at a price that undercuts the big brands, but the software polish and sensor accuracy gap are the real trade-offs for that discount.
Pros
- Large 1.43-inch round AMOLED display on a 46mm case looks and feels premium well below the price of Apple or Samsung watches
- No subscription required for core health and fitness data, unlike Oura or WHOOP
- Built-in GPS plus 24/7 heart rate monitoring covers the basics most casual runners and walkers actually need
- Realistic week-long battery life with regular feature use, and Amazfit's marketed 14-day figure is achievable with always-on and extras turned off
Cons
- Zepp OS app and ecosystem are noticeably less polished and less third-party-integrated than Apple's, Google's, or Garmin Connect's software
- Battery drops roughly 10-15% per day with all sensors and always-on display active, so the marketed 14-day figure requires disabling features many buyers will want
- Health metric accuracy (especially SpO2 and stress scores) is generally considered a step behind Garmin, Apple, and Samsung in independent comparisons
- Fewer third-party app and watch face options than the major ecosystems
This review is based on Amazfit's published specifications for the GTR 4 and the consistent patterns across independent smartwatch reviews and owner feedback, weighing its budget-friendly pricing against the software and accuracy trade-offs it makes.
A premium-feeling display without the premium price
The 1.43-inch AMOLED screen on a 46mm case is genuinely one of the nicer displays available at this price point, and Amazfit backs it with built-in GPS and no ongoing subscription requirement for the core health data — a real point of difference from Oura or WHOOP.
Where the savings show up
The Zepp OS software and app ecosystem are functional but noticeably behind Garmin Connect, watchOS, or Wear OS in polish and third-party integration, and independent testing generally rates its SpO2 and stress metrics as less accurate than the major brands. Battery life also drops fast — roughly 10-15% a day — once you turn on always-on display and full sensor tracking.
Who it's for
Best for budget-conscious buyers who want a big, attractive AMOLED smartwatch with GPS and no subscription fees, and who don't need best-in-class app support or lab-grade sensor accuracy. Choose a Garmin or Apple Watch instead if precise training metrics or a mature app ecosystem matter more than price.
Frequently asked
- Does the Amazfit GTR 4 require a subscription?
- No — core health and fitness tracking data is available in the free Zepp app without a recurring subscription, unlike Oura or WHOOP.
- How accurate is the built-in GPS?
- It has built-in GPS for standalone workout tracking, though independent reviewers generally rate its overall sensor accuracy (including GPS and SpO2) a step behind Garmin, Apple, and Samsung.
- How long does the battery really last?
- Amazfit's 14-day claim assumes always-on display and extra sensors are turned off; with full features active, expect closer to a week, with about a 10-15% daily drain if you're also doing GPS workouts.
- Is the Amazfit GTR 4 worth buying?
- Yes, if you want an attractive big-screen smartwatch with GPS and no subscription at a budget price. It's not worth it if app polish and top-tier sensor accuracy matter more to you than saving money.
