Best Fitness Apps in 2026: 8 Apps Compared

Nike Training Club offers a huge library of free workouts, including strength, HIIT, yoga, mobility and running, with guided programmes for beginners through advanced athletes. That completely free model makes it the best fitness app for most people, since you get quality workouts, video guidance and training plans without a subscription. Workouts range from five minutes to an hour, so they fit busy schedules.

Live classes are not included, and nutrition tracking is limited, so pair Nike Training Club with MyFitnessPal if food tracking matters. For free, high quality guided workouts at home or in the gym, no other app on this list matches Nike Training Club's combination of breadth and price.

Strava is the social network for runners and cyclists, with GPS tracking, route mapping, segments where you compete on specific stretches, and challenges that motivate regular training. Its community features, including kudos, comments and clubs, make solo training feel social, which helps many people stay consistent. The free plan covers core tracking and social features, while Summit adds advanced training analysis.

Summit, Strava's paid tier, is needed for deeper training metrics, route planning and beacon safety features, so serious athletes should consider it. Social comparison can demotivate some users, so focus on your own progress rather than leaderboards, but for runners and cyclists, Strava is the default app for tracking and community.

Fitbod builds personalised strength workouts based on your goals, available equipment, muscle recovery and past performance, adapting each session as you progress. That personalisation suits gym goers who want a plan without hiring a trainer, with exercise videos showing proper form for each movement. It tracks sets, reps, weights and muscle groups, giving a clear picture of training balance.

A subscription is needed after the trial, and Fitbod focuses on strength, so runners and class lovers need another app. If strength training is your main goal and you want a plan that adapts to your equipment and recovery, Fitbod is the best personalised option on this list.

Strong is the simplest strength logging app, letting you build routines, log sets, reps and weights quickly, and view progress charts over time. Its speed matters in the gym, since logging should not interrupt your workout, and its clean interface makes it easy to follow a routine without distraction. The free plan covers core logging, while Pro adds unlimited routines and advanced charts.

Strong does not generate personalised plans like Fitbod, so you need to know what routine to follow, whether from a coach, a programme or your own experience. For lifters who already have a routine and want fast, reliable logging, Strong is excellent and free to start.

MyFitnessPal is best known for nutrition, but it also logs workouts and integrates with fitness apps, wearables and Strava, making it a useful companion to a workout app. Its food database is the largest available, which makes calorie and macro tracking easier, and its daily totals help users balance eating and exercise for weight loss or muscle gain. The free plan covers core logging, while Premium adds macro goals and ad removal.

Workout plans themselves are thinner than Nike Training Club or Peloton, so use MyFitnessPal for nutrition and tracking, not as your main workout source. This is not medical advice, so discuss nutrition and weight goals with a clinician or dietitian if you have health conditions.

Peloton App offers thousands of live and on demand classes in cycling, running, strength, yoga, meditation and more, with motivating instructors and a strong community. You do not need Peloton hardware to use the app, since many classes work with any bike, treadmill or no equipment, but the full experience is best with Peloton equipment. That class variety suits users who need structure and motivation to exercise regularly.

A subscription is needed after the trial, and prices are higher than free apps, so Peloton is best for users who thrive on guided classes and community motivation. If you prefer self directed workouts, Nike Training Club free offers similar variety without the cost.

Apple Fitness+ offers guided workouts in strength, HIIT, yoga, dance, cycling and more, with new workouts weekly and integration with Apple Watch for live metrics on screen. That integration is its main advantage, since heart rate, calories and Activity rings appear during workouts on iPhone, iPad or Apple TV. Production quality is high, with motivating trainers and music.

Full experience needs Apple devices, and there is no Android app, so Android users should choose Nike Training Club or Peloton instead. A subscription is needed after the trial, though new Apple device purchases often include months free, so check for a trial with your device before paying.

Couch to 5K is a free, gradual nine week programme that takes absolute beginners from walking to running 5 kilometres, with audio coaching for each session. Its slow progression, alternating walk and run intervals, makes running accessible to people who have never run before, and its simplicity is its strength. The NHS Couch to 5K app is free and widely used, with a supportive community of new runners.

It covers running only, with no strength or cross training, so pair it with Nike Training Club or Strong for overall fitness. Pace may not suit everyone, so repeat weeks if needed rather than pushing through pain, and talk to a clinician before starting if you have health conditions or have been inactive for a long time.
