Description
Amazfit GTS 4 Smartwatch
The Amazfit GTS 4 pairs a 1.75-inch AMOLED touchscreen with Bluetooth phone calls, advanced fitness tools, and health tracking through the Zepp App on Android and iOS.
Display and design
An ultra-large 1.75″ AMOLED display presents notifications, workouts, and health data in HD clarity. The watch uses a one-piece aluminum alloy middle frame and a gemstone-style stainless steel navigation crown. Customize watch faces through the app to match your style.
Bluetooth phone calls
A built-in microphone and speaker let you answer or place calls from your wrist when your phone is connected via Bluetooth, so important calls are less likely to be missed on the move.
GPS, routes, and navigation
Industry-first dual-band circularly-polarized GPS antenna technology aims for positioning that is 99% as accurate as top handheld GPS locators. Import a route file from the Zepp App and navigate along it in real time on the display. Track movement on your own path, use Direct Return Navigation to see the shortest straight line back to your start point, and benefit from trajectory and distance correction when signals weaken briefly.
Note: Route import will be available via OTA update.
Strength training
Dozens of strength training movements can be recognized automatically. The watch counts reps and tracks rest between sets; after training, the Zepp App shows muscle groups worked and duration for each.
Live sports data broadcast
During exercise, live notifications can play through the watch speaker or Bluetooth headphones for metrics such as heart rate, hydration reminders, and distance covered—without raising your wrist each time.
Note: Live Sports Data Broadcast supports English and Chinese voice broadcasts and will be available via OTA update.
Fitness and sports modes
Choose from more than 150 sports modes, with smart recognition of 8 sports. Create interval training templates for 10 sports on the watch, divide templates into stages loopable up to 30 times, review workouts with PeakBeats, and sync data to Strava. Swimming data can be tracked with water resistance equivalent to up to 50 meters’ water pressure.
Health monitoring
BioTracker 4.0 PPG uses an enhanced 2LED sensor to collect 33% more data than the previous generation for improved accuracy. Enjoy 24-hour heart rate, blood-oxygen saturation, and stress monitoring, plus breathing rate detection and one-tap measurement of all four metrics.
Sleep and morning updates
In-depth sleep tracking covers daytime naps and light, deep, and REM stages, plus sleep breathing quality. A Morning Update summarizes weather, health data, calendar events, and other items you choose—viewable on the watch when you wake.
Voice assistants
Online: Use Alexa for alarms, translations, and more.
Offline: Voice commands can engage sports modes and health features without internet; try “Up Your Game” for a built-in surprise.
Store cards
Add membership and club card codes via the Zepp App and show Code 128, Code 39, or QR codes on the display at checkout. Up to 20 cards per account due to storage limits. Support for UPC A, EAN 13, and EAN 8 will be added via OTA update.
Music
Store music on the watch for playback through the built-in speaker or Bluetooth headphones, or control phone music over Bluetooth.
Zepp OS 2.0

Fall detection
When a fall is detected, the watch can call an emergency contact and send a distress message with location information.
