How to Buy a Fitness Tracker or Smartwatch
This short guide helps you pick the right fitness tracker or smartwatch fast. It covers the main buying factors, the common product categories, the features and specs to compare, and practical buying tips so you can act with confidence.
Key factors to consider
Types to choose from
- Entry-level bands: low price, basic heart rate, SpO2, steps and sleep tracking.
- All-purpose smartwatches: larger screens, notifications, more sport modes, mid battery life.
- GPS sport watches: built-in GPS, training metrics and advanced workout guidance, typically higher cost.
- Health-first devices: advanced sensors like ECG, continuous SpO2, and in-depth sleep analysis, usually premium priced.
Features and specifications to check
- Sensors and accuracy - Confirm continuous heart rate and SpO2; know optical sensors are convenient but not medical grade.
- GPS - Built-in GPS is essential if you want accurate outdoor distance and pace without carrying your phone.
- Battery life - Look for realistic day estimates: 7 to 14 days for many trackers, multi-day for basic models, and up to a day or two for high-refresh bright displays with GPS on.
- Water resistance - IP68 or 5 ATM for swimming and showering.
- Display and controls - Touchscreen vs buttons, brightness for outdoor visibility, and customizable watch faces.
- App and ecosystem - Strong app support gives better trend reports, firmware updates and third-party integrations.
- Build and bands - Removable bands, strap width, and materials affect comfort and replacement options.
- Extra features - Notifications, music control, contactless payments and safety features can matter if you want a smartwatch experience.
- Warranty and support - Check seller warranty length and return options.
