Strava (free tier available, £7.99/month for Summit) is the best running and cycling tracking app in the UK — the largest active community of any fitness tracking platform, widely considered the social network of outdoor endurance sport. MyFitnessPal (free tier, £9.99/month for Premium) leads for calorie and macro tracking. For structured strength training programmes, Strong (free for core logging, £3.99/month for full features) is the most widely recommended gym logging app. For all-in-one guided fitness, Nike Training Club remains one of the strongest free options available.
Fitness apps fall into four distinct categories that serve different needs: activity tracking (GPS running/cycling), calorie and nutrition logging, structured training programmes, and general wellness/coaching. The "best" app depends entirely on which of these you're actually buying it for — mixing up categories is why many people end up with five apps on their phone that collectively do less than they hoped.

Best for Running and Cycling: Strava
Strava's defining advantage over every other activity-tracking app is its community. Segments (virtual race sections on popular routes), kudos from friends, club feeds, and leaderboards create a social layer around outdoor training that GPS tracking apps like Garmin Connect, Apple Fitness+, and Google Fit don't replicate. For many users, the Strava social element is specifically what makes training feel less solitary and more accountable — a real, measurable motivation factor. The free tier covers basic activity recording and social features; Summit ($7.99/month) adds deeper training analysis, route planning, and segment competition. For serious runners and cyclists, Summit is widely considered worth the monthly cost. For casual use, the free tier is genuinely functional.
Best for Calorie and Nutrition Tracking: MyFitnessPal
MyFitnessPal's core strength is the largest food database of any UK nutrition tracking app — a critical advantage for accurate logging, since a food that isn't in the database requires manual entry and reduces tracking consistency. The free tier covers basic calorie logging; Premium ($9.99/month) adds macro tracking detail, no ads, and the ability to log micronutrients — worth it specifically for serious calorie counters or people following a specific dietary approach. Note: food logging apps show you what you're eating but don't make nutritional recommendations — use the data to inform your own decisions rather than treating targets as medical advice.
Best for Strength Training Logging: Strong
Strong is the gym-logging app most consistently recommended in strength training communities — clean, simple interface, tracks progressive overload across sessions, and calculates estimated one-rep maxes. The free tier logs workouts but limits historical tracking depth; the paid tier (£3.99/month) unlocks full history, workout statistics, and additional programme features. If your primary training is strength-based rather than cardio, a dedicated gym logging app like Strong genuinely changes how consistently you apply progressive overload — the practice of incrementally increasing training demand over time that's most reliably associated with strength and muscle development.
Best Free All-Rounder: Nike Training Club
Nike Training Club is genuinely unusual in the fitness app market: it's essentially fully-featured at no cost. Hundreds of guided workouts across strength, yoga, HIIT, and mobility, with video demonstrations, multiple difficulty levels, and structured training plans — all free, no subscription required. Its absence of a paid tier removes the upsell pressure that many "free" fitness apps use as their primary business model. The trade-off is that it's less good as a personalised tracking and progression tool — it guides workouts but doesn't specifically track your individual progression the way Strong does for lifting or Strava does for running.
Best for Complete Beginners to Running: NHS Couch to 5K
NHS Couch to 5K is the most widely used beginner running programme in the UK, available as a free official app from the NHS. Its structured 9-week programme of walk-run intervals has a proven track record for bringing genuinely sedentary adults to 5K capability, and it's the most trustworthy starting point for anyone new to running specifically. Free, no subscription, NHS-backed.
Building the Right Stack for Your Goal
Most people don't need every category — the right combination depends on what you're actually training for. If strength is the priority, Strong plus a free tracking app for cardio covers it. If running or cycling is the goal, Strava alone often suffices, with Summit as a later upgrade once you're training seriously enough to want deeper analytics. If body composition or a specific nutrition goal is the driver, MyFitnessPal is worth adding regardless of your training format. Layering all four categories at once is rarely necessary for a beginner and more often leads to app fatigue than better results — start with the one category that matches your actual current goal, and add a second only once the first is a genuine habit.
How We Chose
We weighted genuine free-tier functionality (not just a lead magnet for the paid tier), community and social features where relevant to the category, UK food database quality for nutrition apps, and the specific match between the app's primary strength and the use case it's recommended for — rather than scoring a single "all-in-one" winner.
