Prime Days: Best Smartwatch and Health Tracker Deals in 2026!
In a Nutshell
Rob recommends the Fitbit Air ($99) and Amazfit Helio Strap ($9) as the top budget devices, delivering excellent heart rate tracking (especially on the biceps) and strong sleep stage accuracy with fully free apps. The Pixel Watch 3 leads budget wrist-based HR monitors, while the Fitbit Charge 6 tops sleep tracking at ~$80-100. These older-generation devices offer the best value when discounted during Prime Day sales.

The video focuses on affordable smartwatches and sports watches for health and sports tracking, with emphasis on devices likely on sale during events like Amazon's Prime Days. These older-generation devices tend to be discounted regularly, providing good value regardless of purchase timing. The presenter is Rob, a post-doctoral scientist specializing in biological data analysis, who prioritizes data-backed recommendations.
The video is structured into three main sections: best sports watches focusing on wrist-based heart rate tracking, best sleep and recovery health trackers, and best overall devices that combine both capabilities with good app experience. For each category, the top three devices are presented along with honorable mentions. Premium expensive devices are excluded to focus on budget options that enable health tracking without high costs.
Two strong heart rate trackers are reserved for later discussion in the overall best devices section. The third-ranked budget option is the Huawei Watch Fit 4 and 4 Pro. These devices resemble Apple Watches in appearance but cost significantly less while delivering solid heart rate tracking performance.
Testing data for the Huawei Watch Fit 4 Pro shows near-perfect correlation of 1.00 against an ECG chest strap reference during indoor cycling, with all data points closely aligned to the reference line. Example sessions demonstrate excellent agreement across intervals. Running tests show most points on or near the reference line with only minor deviations. Outdoor cycling also performs well with most points aligned and only small moments of deviation. Weightlifting shows good overall performance but misses some heart rate peaks in higher ranges.
