Buying Guide

Fitness Smartwatch Buying Guide

Garmin vs. Apple vs. Samsung for Fitness

Garmin leads on training analytics (Training Readiness, VO2 max, race predictor). Apple leads on ecosystem integration and cardiac health features. Samsung is catching up with Galaxy AI Running Coach. Choose based on how seriously you train.

Training Readiness and Recovery

Garmin's Training Readiness score combines HRV, sleep quality, training load, and stress into a single score telling you how ready you are to train. Apple and Samsung don't offer an equivalent — this is Garmin's biggest competitive advantage.

GPS Accuracy Matters

For runners and cyclists tracking distance and pace, multi-band GPS (available on Fenix 8, Venu 4, Forerunner 265, Pixel Watch 4) is significantly more accurate than single-band GPS — especially in cities and under tree cover.

Heart Rate Accuracy

Chest straps remain the most accurate. Among wrist-based sensors, Pixel Watch 4 (Fitbit algorithms) and Apple Watch test best. Garmin is excellent. Samsung is good. For high-intensity interval training, accuracy drops on all wrist-based options.

Battery for Long Events

Marathons take 3–6 hours. Ultra-marathons can take 24–50+ hours. Apple Watch Series 11 barely covers a marathon. The Fenix 8 (19 hrs GPS), Venu 4 (20 hrs GPS), and Forerunner 265 (20 hrs GPS) are built for long events.

Water Resistance for Swimmers

Most smartwatches are rated to 50m. The Fenix 8 is dive-rated to 40m. Apple Watch Ultra 3 is dive-rated to 100m. If swimming is your main sport, check the specific water resistance rating carefully.
