Fitness trackers are adding more health features, making it hard to tell them apart. In this guide, we’ll look at what these devices can do. We’ll cover their pros and cons, who should use them, and the best models for 2025. This will help you choose the right device for you.
Understanding Smartwatches and Fitness Trackers
What is a Smartwatch?
A smartwatch is a versatile device. It extends your smartphone’s capabilities and offers more than just fitness tracking. It includes:
- Notifications for calls, messages, and apps
- Music streaming and control
- Voice assistants (e.g., Siri, Google Assistant, Alexa)
- Mobile payments (e.g., Apple Pay, Google Pay)
- Customisable watch faces and third-party apps
- Advanced fitness and health tracking
- Navigation and GPS for outdoor activities
- Ability to make and receive calls independently (for LTE-enabled models)
Smartwatches are designed for users who want a balance between productivity, fitness, and connectivity.
What is a Fitness Tracker?
A fitness tracker, also known as an activity band, is a streamlined device focused on health and wellness. It primarily monitors:
- Step count and daily activity
- Heart rate and sleep patterns
- Calories burned
- Workout tracking and sport-specific metrics
- Blood oxygen and stress levels (in newer models)
- Battery-efficient performance with a minimalist design
Fitness trackers are best suited for individuals who prioritise health tracking and long battery life over advanced smartwatch capabilities.
Wearable Comparison: Smartwatches vs Fitness Trackers
1. Design and Comfort
- Smartwatches: Typically larger with a touchscreen display, premium materials, and a more stylish look. Some models feature interchangeable straps and custom watch faces, making them more versatile as fashion accessories. However, their larger size can sometimes make them less comfortable for all-day wear.
- Fitness Trackers: Slim, lightweight, and designed for all-day wear. Many models have a discreet screen or none at all, prioritising comfort over aesthetics. They are often made of flexible, durable materials to withstand intense workouts.
Winner: Fitness trackers for lightweight comfort; smartwatches for style and premium design.
2. Health and Fitness Tracking
- Smartwatches: Offer in-depth tracking with ECG monitoring, blood oxygen levels, VO2 max, AI-driven workout coaching, and even hydration reminders. High-end models can detect irregular heart rhythms and provide detailed insights into overall health.
- Fitness Trackers: Focus on basic activity metrics such as steps, heart rate, sleep, and calorie burn. While they are getting more advanced, they still lack some of the high-tech health monitoring features found in smartwatches.
Winner: Smartwatches for advanced health metrics; fitness trackers for casual fitness tracking.
3. Battery Life
- Smartwatches: Usually last 1-3 days due to high-resolution screens and multiple features. Some premium models offer power-saving modes to extend battery life.
- Fitness Trackers: Can last up to 10-14 days on a single charge due to minimal display usage. Some models, like the Whoop Strap 5.0, have a continuous charging option via an external battery pack.
Winner: Fitness trackers for long-lasting battery life.
4. Smart Features and Connectivity
- Smartwatches: Support messaging, phone calls, contactless payments, and third-party apps. Some even include LTE connectivity, allowing you to use them independently from a smartphone.
- Fitness Trackers: Limited to fitness tracking, notifications, and basic call alerts. Most do not have app stores or advanced connectivity options.
Winner: Smartwatches for productivity and smartphone integration.
5. Pricing and Affordability
- Smartwatches: Higher price range (£200-£1,000) due to advanced features and premium build.
- Fitness Trackers: Budget-friendly (£50-£250), making them a great choice for cost-conscious buyers.
Winner: Fitness trackers for affordability; smartwatches for feature-packed value.
