UK fitness tracker guide
Most fitness trackers were built for a US audience first. Features that matter to UK users - UK food barcodes, UK product databases, a focus on what people actually eat here - tend to be an afterthought. This guide covers what to look for and where the popular options land.
Free to use. No subscription required.
What actually matters
Most fitness apps compete on feature count. These are the four things that determine whether you actually keep using one.
Scanning packaged food should not cost money. If a tracker paywalls barcode scanning or the macro breakdown, you end up paying just to log your own food. Look for one where the core tracking stays free.
Most people who track food also go to the gym. A fitness tracker that only handles food sends you back to a separate workout app. The best ones cover both under the same login.
Progress in the gym is built on what you do daily - sleep, hydration, protein, steps. A tracker that includes habit check-ins means you see how your routines and your results connect.
Your weight fluctuates by a kilogram or two day to day. A good tracker shows you the trend across weeks, not the noise of individual weigh-ins, so you know whether progress is real.
Types of fitness app
Most popular fitness apps specialise in one area. That means most people end up with two or three apps that never talk to each other. Here is how the three types break down.
MyFitnessPal, Lifesum, Cronometer
Hevy, Strong, Gymbook
Go Gym
The non-negotiables
These are the features you should expect before paying anything. If a fitness app paywalls any of them, look elsewhere.
Our recommendation
Go Gym is an all-in-one fitness tracker built in the UK for UK users. The food database is UK-first, barcode scanning works with UK supermarket products, and the core features - calorie and macro tracking, workout logging, habit check-ins, and weight trending - are all free with no cap on how much you log.
The goal is to replace the stack of separate apps most people run. Your food, training, habits, and weight live in one place. A weekly review shows you the full picture - not four disconnected screens.
Go Gym is free to use in the UK. Sign up and get started.

Common questions
The best free fitness tracker for most UK users keeps calorie tracking, barcode scanning, and macro breakdown genuinely free - without paywalling your own data. Go Gym is built UK-first with those core features free, plus workout logging, habit tracking, and weight trending in one app.
Most popular fitness trackers were built for a US audience first. Go Gym is built in the UK from the ground up, with UK supermarket barcodes and UK food products as the starting point rather than an afterthought.
No. An all-in-one fitness tracker like Go Gym covers both in one place. Running separate food and workout apps means your data never joins up - a weekly review becomes guesswork. One app with one login is simpler and more informative.
It depends on what you get. A subscription makes sense if you genuinely use advanced features like curated meal plans, coaching programmes, or deep device integrations. It is not worth paying just to see your own macros, scan a barcode, or access your weigh-in history - those should be free.
Look for: free core tracking (calories, macros, workouts), barcode scanning with UK supermarket products, weight trend graphs rather than just daily numbers, and habit check-ins. Bonus points for all four in one app with no paywall on basic functionality.
