How to choose a smartwatch

Start with the phone you use. Then decide which features you will use every day, and check battery life and water resistance against how you live.

  • Compatibility: check the watch works with your phone (Android, iPhone or both) and which companion app it uses.
  • Calling: Bluetooth calling watches have a microphone and speaker so you can answer calls from your wrist while your phone is nearby.
  • Health and fitness: look for step counting, heart-rate monitoring, sleep tracking and sport modes if activity tracking matters to you.
  • Battery: feature-rich watches with bright screens often need charging every 1 to 2 days; simpler watches can last a week or more.
  • Water resistance: check the rating (for example IP67, IP68 or 5ATM) before swimming or showering with the watch.

Typical features include call and message notifications, step and calorie counting, heart-rate monitoring, sleep tracking, sport modes, alarms, timers, weather and music controls. Exact features vary by model, so check the specification table on each product page.

Do smartwatches work with phones?

Yes. Most smartwatches pair with a smartphone through a companion app. Some work with both Android and iPhone, while others are limited to one platform, so always check the compatibility section before you buy.
