Best 10 Fitness Tracker Apps in 2026: Features Compared Side by Side

Fitbit is the best overall fitness tracker app. It covers activity, sleep and heart rate, and its basic tracking works without a Fitbit device. This list covers 10 mobile apps, from all-purpose trackers to running, strength and wearable companion apps. Picks are based on verified listings, not hands-on testing.

Quick comparison table

Every app below lists iOS and Android support, though Samsung Health's iOS support is limited. Strava, Peloton and Fitbod work on their own. Garmin Connect, Zepp and Samsung Health make the most sense with matching devices. Pricing wasn't in the listings we checked, so it's marked Unknown.

1. Fitbit

Best for: All-round daily activity, sleep and heart rate tracking.

Fitbit's big draw is that activity, sleep and heart rate data all live in one app. Basic tracking works even if you don't own a Fitbit device. Most people who want one general tracker will be happy here. Lifters and serious runners may prefer something more focused.

2. Strava

Best for: Runners and cyclists who want GPS tracking.

Strava records runs and rides with GPS and handles other activities too. Its social feed is what sets it apart. You share workouts and see what others are up to. If community keeps you moving, it's a good fit. If you'd rather train quietly, it may feel like extra noise.

3. MyFitnessPal

Best for: Tracking food and calories alongside exercise.

This is a calorie counter and food diary that also logs exercise. It syncs with popular wearables and fitness devices, so your activity can sit next to your meals. The trade-off: it's nutrition-first, not primarily a workout tracker.

4. Samsung Health

Best for: Galaxy device owners.

Samsung Health tracks steps, workouts and sleep. It's tuned for Galaxy devices, so it works best inside Samsung's own ecosystem. iOS support is limited, so iPhone users should look elsewhere.

5. Google Fit

Best for: Wear OS watch users who want simple goal tracking.

Google Fit tracks your activity and lets you set fitness goals. It works with Wear OS watches, which is its main selling point. It's a sensible pick if you want something simple rather than feature-heavy.

6. Nike Run Club

Best for: Runners who want guided runs.

Nike Run Club tracks your runs with GPS. Its guided runs from Nike give you something to follow instead of just a map and a timer. It's running-focused, so it's less useful for gym sessions or all-day tracking.

7. Garmin Connect

Best for: Garmin device owners who want detailed data.

Garmin Connect is the companion app for Garmin devices. It stores and analyzes your activity, sleep and health data, and its in-depth analysis of what your Garmin collects is the main reason to use it. It's built around Garmin hardware, so it's of little use without one.

8. Peloton

Best for: People who want instructor-led classes at home.

Peloton offers on-demand and live workout classes. It works without Peloton hardware, so you don't need the bike or treadmill. It's class-driven rather than a passive tracker. Expect to follow sessions, not just log steps.

9. Zepp

Best for: Amazfit and Zepp wearable owners.

Zepp tracks activity, sleep and health metrics. It's the dedicated companion for Amazfit and Zepp wearables, and it's mainly useful if you own one of those devices.

10. Fitbod

Best for: Lifters who want a ready-made plan.

Fitbod generates workout plans and logs your lifts. Those automatically generated strength plans save you from building routines yourself. It focuses on strength training, so it won't track steps or sleep.

Frequently asked questions

What is the best fitness tracker app overall?

Fitbit. It covers activity, sleep and heart rate in one place, and its basic tracking works without a Fitbit device.

Do I need a wearable?

Not always. Fitbit's basic features and Peloton work without special hardware. Garmin Connect and Zepp are tied to their own devices.

Which app is best for runners?

Strava suits runners who want GPS tracking and a social feed. Nike Run Club is better if you want guided runs.

Which app works best on iPhone?

Fitbit, Strava and the other apps here list iOS support. Samsung Health's iOS support is limited, so iPhone users should pick something else.

Can I track food and workouts together?

The verdict

Fitbit is the strongest overall pick. It covers activity, sleep and heart rate, and you don't need a Fitbit device to get started.

Strava is the runner-up for GPS activity and community, and MyFitnessPal is the one for food-plus-exercise logging. If you own a device, choose Garmin Connect, Zepp or Samsung Health. Otherwise, pick by use case: Fitbod for lifting, Peloton for classes.
