A modern smartwatch still tells the time, but it can also connect to a compatible phone, track activity and sleep, and provide health-related measurements. Some models add emergency features or work without a phone nearby in specific configurations. What you can actually use depends on the watch, phone, setup, connectivity, and location.
What a smartwatch adds to telling time
A smartwatch is best understood as a wrist-worn companion to a compatible phone. Alongside the clock, its software and sensors can bring together connected-phone functions, activity and sleep tracking, and health-related measurements. The exact mix varies by brand and model: Apple describes health, fitness, and safety as Apple Watch categories; Google documents activity and sleep tracking for Pixel Watch; Samsung documents access to health-related sensor measurements. These are examples of each maker’s product capabilities, not a guarantee that every watch offers the same functions.
How tracking and health measurements fit in
Activity and sleep
Depending on the model and its software, a watch can record activity or sleep information and present it through the maker’s companion services. Google documents activity and sleep tracking for Pixel Watch, while Apple includes fitness among its Apple Watch features. Check the exact model’s feature list to see which measurements it records and what phone or app setup is required.
Health-related readings are not automatically a diagnosis
Wrist sensors can provide measurements and wellness information, but a reading is not, by itself, a medical diagnosis. Samsung’s Health Sensor SDK explicitly says its measured data is for fitness and wellness information, not for diagnosing or treating a medical condition. That is Samsung’s stated limitation; readers should consult the documentation and intended use for their specific device and feature.

Manufacturer claims apply to the named model
In its September 2026 announcement, Apple said Apple Watch Series 12 measures heart rate every five seconds with its optical heart sensor. That interval is Apple’s claim for Series 12, not a benchmark for all smartwatches or evidence that every watch measures at the same rate. Apple’s Series 12 announcement
In the same announcement, Apple vice president of Health and Fitness Sumbul Desai, M.D., said: “By combining breakthrough sensing on Apple Watch with Apple Intelligence in the Health app, we’re able to translate complex biometric data into clear guidance for users.” This is a company statement about its product, not independent evidence of clinical accuracy.

When safety features may help—and what to verify
Some smartwatch models include emergency or other safety functions, but availability is conditional rather than universal. Google’s Pixel Watch help documentation lists safety features for LTE versions of Pixel Watch 2, 3, and 4 that can be used with or without the phone nearby. That statement applies to the listed watches and features; it should not be extended to every Pixel Watch function or to watches from other brands.
Before relying on a safety function, check the exact model, whether it requires LTE or another connection, the setup and eligibility conditions, and whether it is available where you live. Google’s help page describes the relevant Pixel Watch conditions: Pixel Watch safety features.

How to choose a smartwatch that fits your phone and needs
- Check phone compatibility first. Confirm that the watch supports your phone and the companion app or services you intend to use. Compatibility determines whether connected features and setup are available to you.
- Choose the tracking you care about. Compare the exact model’s activity, sleep, and health-related features against your needs. Brand-level feature categories do not establish that every model has every sensor or measurement.
- Verify connectivity and safety conditions. If you want functions to work when your phone is not nearby, confirm whether the particular watch needs LTE, how it must be configured, and whether the feature is supported in your region.
- Check model and regional availability. Feature eligibility can vary by model, software, setup, and location. Use the manufacturer’s current documentation for the specific watch you are considering.
Apple, Google, and Samsung describe their own feature sets in their official materials: Apple Watch health, fitness, and safety, Google Pixel Watch help, and Samsung Health Sensor SDK. These sources establish manufacturer-documented capabilities and limitations; they do not provide an independent accuracy comparison or a universal ranking of current watches.
