There are thousands of fitness apps in the app stores, and most of them try to become your coach, tracker, diary, meal plan, and subscription bundle at once. The useful ones tend to have a narrower job: track a run, log meals, guide a beginner, or keep recovery visible. Pick the app that matches the habit you actually want to build.
Prices, features, and free tiers change often. Confirm the current plan on the developer’s site before subscribing, and check the App Store / Google Play privacy labels to see what each app collects.
What earned a place
We looked for a long track record, active development, sensible privacy practices, and a free tier that does something useful. Apps that bury basic features behind aggressive upsells lost ground. We also skipped thin white-label “AI coach” apps that have appeared and disappeared in the last two years.
Use this as a shortlist. Your gym, watch, clinician, or family routine may push you toward one option over another.
1. Strava - best for runners and cyclists
Strava is the default social network for endurance athletes. The free tier still covers what many runners and cyclists need: GPS tracking, basic pace and elevation stats, segments, and route sharing. The paid tier adds heatmaps, route building, and live segment racing.
Use it for outdoor running, road and gravel cycling, swimrun, or walking routes. The catch is that the strongest planning and analysis tools sit behind the paid tier. Find it at strava.com for iOS, Android, and web.
2. MyFitnessPal - best for nutrition tracking
MyFitnessPal has the largest crowd-sourced food database, which matters more than a flashy dashboard when you are scanning barcodes at a supermarket. The free tier still covers logging and macro totals. Premium unlocks meal plans, food analysis, and custom macro targets.
It is best used for calorie awareness, macro tracking, and recipe logging. Because many entries are user-submitted, spot-check the foods that matter most to your plan. Find it at myfitnesspal.com for iOS, Android, and web.
3. Apple Fitness+ - best class library inside the Apple ecosystem
If you already own an Apple Watch, Fitness+ stitches heart rate, calorie burn, and rings into every guided workout. It covers strength, HIIT, yoga, Pilates, treadmill, cycling, rowing, and meditation. Family Sharing makes more sense for couples and households than for one casual user.
The obvious audience is Apple Watch owners who want guided sessions on an iPhone, iPad, or Apple TV. Full functionality requires both Apple hardware and a recurring subscription. Find it at apple.com/apple-fitness-plus.
4. Nike Training Club - best free home-workout library
Nike Training Club is one of the few major fitness apps where the core content is still free. The library covers bodyweight strength, mobility, yoga, and short HIIT sessions led by named Nike trainers, with filters for equipment and duration.
It is a practical starting point for home workouts with little equipment and limited time. Programming is broad rather than personalised, so it does not replace coaching. Find it at nike.com/ntc-app for iOS and Android.
5. Peloton App - best for live and on-demand classes without the bike
The Peloton App One and App+ tiers let you take Peloton’s cycling, running, strength, yoga, and meditation classes without owning the bike. The instructor roster and music licensing are the draw, with classes filterable by length, instructor, and music genre.
It suits people who like instructor-led group energy and a deep on-demand catalogue. Cycling and rowing classes become much more useful with compatible equipment. Find it at onepeloton.com/app for iOS, Android, web, and TV.
6. Strong - best minimalist strength training tracker
Strong is a plain lifting log: build a routine, log sets and reps, and review a clean history of your lifts over time. It does not try to be a coach, a social network, or a nutrition app, which is exactly why serious lifters keep using it.
It fits lifters running structured programmes such as 5x5, 5/3/1, or PPL. You bring the programme; Strong records the work. Find it at strong.app for iOS and Android.
7. Down Dog - best for flexible yoga sessions
Down Dog generates a new yoga sequence every time, with controls for level, focus area, voice, music, and session length. The same studio publishes specialist apps for HIIT, barre, running, and prenatal yoga, all with the same clean interface.
It works for home yoga practitioners who do not want to repeat the same recorded class. The instruction is functional rather than charismatic; it is a sequence generator, not a star teacher. Find it at downdogapp.com for iOS, Android, and web.
8. Headspace - best for recovery, sleep, and stress habits
Headspace has polished beginner meditation onboarding plus sleep and “Move Mode” libraries that pair naturally with a training routine. It is also one of the few wellness apps that publishes its own clinical research, which is unusual in this category.
Use it for stress management, sleep routines, and short mindfulness breaks. Meditation apps can support wellbeing, but they do not replace mental-health care when you need it. Find it at headspace.com for iOS, Android, and web.
9. NHS Couch to 5K - best free beginner running plan
The UK NHS’s Couch to 5K is a free, ad-free, government-backed nine-week programme that takes complete beginners from the sofa to a 30-minute run. Each week’s sessions are guided by one of several presenter voices. There are no subscriptions, ads, or upsells.
This is the cleanest pick for complete beginners who want a structured running plan at no cost. The app is intentionally limited; after week nine, you will likely move to Strava or another structured plan. Find it via nhs.uk for iOS and Android.
10. Garmin Connect - best wearable companion if you own a Garmin watch
Garmin Connect is unusually capable for a free companion app: training load, recovery time, sleep stages, Body Battery, course planning, and a clean activity history. If you already wear a Garmin watch, ignoring the app means leaving much of the device unused.
It is only useful if you own compatible Garmin hardware, but for Garmin users it should be the anchor app. Find it at connect.garmin.com for iOS, Android, and web.
Choosing without app clutter
- Pick one app per habit, not five. Tracking burnout is real.
- Check the App Store / Google Play privacy labels before connecting your watch, scale, or health data.
- Use a free tier for a full month before paying - most apps reveal their weaknesses in week two.
- If you wear a watch (Apple Watch, Garmin, Fitbit, Whoop), the maker’s own app is usually the right anchor.
- Cancel anything you stop opening within 30 days. Subscription drift is the biggest fitness-app problem most users have.
Fitness app questions
Do I need to pay for a fitness app to see real results?
No. Nike Training Club, NHS Couch to 5K, and Garmin Connect deliver useful features at no cost. The paid tiers on apps like Strava and MyFitnessPal add analytics and personalisation, but they’re not necessary for most people building a basic habit.
Which fitness app is best for complete beginners?
NHS Couch to 5K is the clearest entry point for running beginners - no ads, no upsells, structured progression. For home strength training, Nike Training Club’s free bodyweight library is the best starting point. Both avoid the aggressive subscription pressure that plagues most apps in this space.
Can I use multiple fitness apps at once?
You can, but tracking fatigue is real. The most effective approach is one tracking app (Strava or Garmin Connect for movement data) and one coaching or class app (Fitness+ or Peloton). More than two active apps usually means you’re spending more time managing data than actually training.
How do I know if a fitness app is collecting too much of my data?
Check the App Store privacy label (iOS) or Google Play Data Safety section (Android) before downloading. Look for what data is linked to your identity and what’s shared with third parties. Avoid apps that require access to contacts, camera, or location beyond what the core functionality needs.
