Why buy each?

Xiaomi Smart Band 9

AMOLED always-on at under $40

Most fitness trackers at this price use basic LCD displays. The Smart Band 9 brings a vivid AMOLED always-on screen — rare at this price point.

14-day battery with health monitoring

Continuous heart rate, SpO2, stress, and sleep tracking — all running for 2 weeks before charging. Most smartwatches last 1–2 days.

Works with iPhone and Android

Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends.

COROS Pace

38-day battery in a 30g watch

At 30 grams, the Pace 3 is among the lightest GPS watches available — yet delivers 38 days typical use and 17 hours continuous GPS.

Multi-band GPS at entry price

Dual-frequency L1+L5 GPS typically found on $400+ watches — available on the Pace 3 at $229.

COROS EvoLab analytics

Running power, training load, base fitness, threshold metrics, and race predictor — a serious analytics suite that rivals Garmin at a lower cost.
