“Fitness tracking app” covers genuinely different goals — nutrition, athletic performance, and general health monitoring aren't the same problem, and these three apps are each built around one of them primarily.
MyFitnessPal: nutrition and calorie tracking first
MyFitnessPal Premium is built around food logging — one of the largest food databases of any nutrition app, barcode scanning, and macro tracking. If your primary goal is weight management or hitting specific nutrition targets rather than tracking workouts themselves, MyFitnessPal's food database depth is the deciding factor over the other two.
Strava: built for runners and cyclists specifically
Strava Subscription is the standard for endurance athletes — detailed route mapping, segment leaderboards (compete against other users on the same stretch of road or trail), and training load analysis built specifically around running and cycling. If you're training for a race or just want the social/competitive layer of comparing routes with other athletes, Strava's segment and leaderboard features are unmatched by general fitness apps.
Fitbit Premium: wearable-integrated health insights
Fitbit Premium is the right fit specifically if you already own Fitbit hardware — it unlocks deeper analysis of the data your device is already collecting (sleep stages, stress management score, readiness) rather than functioning as a standalone app. It's not a good pick without the hardware, unlike MyFitnessPal or Strava which work fully without a specific wearable.
These three combine well
Unlike some categories in this guide, these three aren't mutually exclusive — a common setup pairs MyFitnessPal for nutrition with Strava for workout tracking, both feeding data into a wearable's Fitbit Premium insights. They solve different parts of the same overall goal.
Data export matters if you switch later
All three allow exporting your historical data in some form, but the completeness of that export varies — before committing years of logged workouts or nutrition data to one platform, it's worth checking what a full data export actually includes, since some platforms preserve more historical detail on export than others.
Community and social features differ meaningfully in how motivating they are day to day — Strava's segment leaderboards create a genuinely different, more competitive social dynamic than MyFitnessPal's more private logging approach, which is worth factoring in if external accountability and competition motivate you more than private tracking.
Integration between all three is actually quite good — Strava can sync activity data into MyFitnessPal for adjusted calorie targets, and both can feed into a Fitbit's broader health dashboard, so running more than one together is a common and well-supported setup rather than a conflict.
Barcode database coverage for regional or international grocery products varies in completeness across nutrition apps — if you shop for groceries outside the US specifically, it's worth checking database coverage for your region before assuming every product you buy will scan successfully.
All three support exporting summary reports as PDF or CSV, useful if you want to share progress with a coach or trainer outside the app itself.
Quick FAQ
Which app is best for calorie and macro tracking? MyFitnessPal is the strongest fit when food logging, calorie targets, and macro tracking are your main priorities.
Is Strava better for running and cycling? Yes, especially if you value route tracking, segments, leaderboards, and training-focused features for endurance activities.
Do I need a Fitbit device for Fitbit Premium? Fitbit Premium is most useful with compatible Fitbit hardware because many of its deeper insights depend on device-collected health and activity data.
The bottom line
Focused on nutrition: MyFitnessPal. Training for running or cycling: Strava. Already own Fitbit hardware: Fitbit Premium. All three, plus meditation and sleep apps, are in Health & Fitness.
