Best Workout Tracker Apps UK 2026: Strength, Cardio and Food in One Diary

Last reviewed: 28 May 2026

Published 28 May 2026 • App Guides • 10 min read

We're NutraSafe — a UK food diary that also logs workouts. We get asked which workout-tracker apps are worth using if you want to keep an eye on the food side too. Here's what each of the six apps in this comparison does, including ours, with what's free and what's paid.

Drawn from each app's public UK App Store listing in May 2026, plus our team's working knowledge of the category. We haven't run controlled head-to-head tests; if we've got something wrong on a specific feature, the contact page reaches us.

Quick answer

NutraSafe (ours): the only one in this list that puts strength logging, cardio and food in the same diary. Workouts is a Pro feature — £3.99/month, iOS. Strong and Hevy: long-established strength-only trackers with free tiers and paid subscriptions; no food side. Fitbod: AI generates your session for you; subscription-based; no food side. MyFitnessPal: food-first, with a cardio log; strength tracking is rudimentary. Apple Fitness+: trainer-led classes that need an Apple Watch; no food side.

If you treat training and food as one project — fuel, work, recovery — running two apps means copying numbers between them and hoping the two calorie-burn estimates agree. If you treat training as its own thing and food doesn't enter the picture, the strength-specialist apps go deeper. Below is what each does, so you can pick the one that matches what you actually want to track.

The 6 main workout tracker apps for UK users in 2026

1. NutraSafe (ours) — strength, cardio and food in one diary

Full disclosure: this is our app. Everything below describes what we built and what's free vs Pro.

What it does: Our workout tracker logs strength sessions (sets, reps, weight), cardio distance, and rests — with a full-screen rest timer that minimises to a pill so you can scroll through your phone while it counts down. Per-exercise history surfaces what you lifted last time you did that lift, so you know whether to push. Heart-rate zones come in through HealthKit during a live session. The four-week calendar shows every workout at a glance, and the AI Coach (Pro) can generate a workout plan based on what you've logged. Crucially, the workouts sit in the same diary as your food, so the calories you log against the calories you burn are the same numbers, not two estimates from two apps.

Price: Free to download. Workouts is a Pro feature. NutraSafe Pro is £3.99/month (iOS, monthly only) and unlocks workouts, AI Coach, AI meal scan, vitamin and mineral tracking against UK NRVs, allergen warning detail, fasting features and full reaction-pattern analysis.

Who we built it for: people who want the strength and cardio side and the food side in one diary — not three apps glued together with manual copy-paste.

What's in the app

  • Strength logging — sets, reps, weight per exercise
  • Cardio logging — distance entries on top of the same workout
  • Rest timer with full-screen and minimised-pill modes
  • Per-exercise history (your last sets appear when logging a new one)
  • HealthKit heart-rate zones during live sessions
  • Four-week calendar of completed workouts
  • Workout trends in the Progress tab
  • AI Coach (Pro) — generates workout plans
  • Same diary as food + calories and reactions

Things to know

  • iOS only at launch — Android in development
  • Workouts is Pro-only (£3.99/month)
  • Smaller exercise library than the strength specialists
  • No bar/plate-loading calculator (yet)
  • NutraSafe Pro is monthly only — no annual tier

Get NutraSafe on the App Store

2. Strong Workout Tracker — established, strength-focused

What it does: A long-running strength-training app. Log sets, reps and weight against routines you build yourself or import. Rest timer, plate calculator, body-measurement tracking, simple progress charts.

Price: Free tier covers a small number of routines and basic logging. A paid tier unlocks unlimited routines and extras (subscription, billed monthly or annually — check the App Store for the current UK price).

Who it's for: lifters who want a focused, well-known strength tracker and don't mind running a separate app for food.

What's in the app

  • Clean, simple set logging — the standard the others were measured against for years
  • Plate calculator
  • Body-measurement tracking
  • iOS, Android and Apple Watch
  • Established user base, large community

Things to know

  • Doesn't track food
  • Cardio is limited
  • Free tier caps the number of routines you can save
  • You'll need a second app for the calorie / nutrition side

3. Hevy — modern strength tracker with social

What it does: A more recent strength tracker with a polished interface, a large exercise library, RPE / RIR fields, and a social feed where you can follow other lifters and share routines.

Price: Free tier covers core set-and-rep logging. Hevy Pro is a paid subscription that unlocks unlimited routines, longer history, and analytics (check the App Store for the current UK price).

Who it's for: lifters who want a modern, polished app and either a social angle or features that exceed Strong's free tier.

What's in the app

  • Clean modern UI
  • Large exercise library with images and videos
  • RPE / RIR fields for periodised training
  • Social — follow, share, copy routines
  • iOS, Android and Apple Watch

Things to know

  • Doesn't track food
  • Free tier is generous but Pro unlocks routines, history range, deeper analytics
  • Cardio support exists but isn't the focus
  • You'll need a second app for the calorie side

4. MyFitnessPal — food first, with a workouts section

What it does: Best known as a calorie counter with a very large user-generated food database. Workouts are a secondary section — manual cardio entries (time + estimated burn) sit alongside the food log. Strength tracking exists but isn't where the engineering went.

Price: Free tier supported by ads. Premium is a monthly or annual subscription (check the App Store for current UK pricing).

Who it's for: calorie counters who occasionally log cardio and want the largest possible food catalogue.

What's in the app

  • Very large food database (user-generated, 14M+ entries)
  • Integrates with Fitbit, Apple Health, Garmin
  • Cardio entries auto-deduct from your remaining calorie budget
  • Recipe importer
  • iOS + Android, established community

Things to know

  • Strength logging is basic — not designed for sets / reps / weight as the primary loop
  • Cardio uses estimated calorie burn — not a measured figure
  • Free tier supported by ads
  • User-submitted food entries vary in accuracy

5. Fitbod — AI-generated strength workouts

What it does: Tell it your equipment, your goal and your recovery state, and it generates a session for you — choosing the lifts, sets and weights. You log as you go and it adapts the next session based on what you actually did.

Price: Short free trial, then a paid subscription (check the App Store for current UK pricing).

Who it's for: people who don't want to plan their own training — they want a coach in their pocket telling them what to lift today.

What's in the app

  • Personalised, adaptive workouts
  • Useful if you don't want to design your own programme
  • Exercise library with form-cue videos
  • Recovery-aware — tracks muscle fatigue across sessions
  • iOS, Android and Apple Watch

Things to know

  • Doesn't track food
  • Subscription required for ongoing use after the trial
  • You hand the programming choices to the app — less suited if you already follow your own programme
  • You'll need a second app for the calorie side

6. Apple Fitness+ — Apple Watch-led trainer classes

What it does: A streaming class library you watch on iPhone, iPad or Apple TV, with your Apple Watch driving the heart-rate, calorie and activity metrics on screen. Classes across strength, HIIT, yoga, cycling, treadmill, dance, meditation and audio runs.

Price: Paid subscription, with a free trial when you buy a recent Apple Watch (check the App Store for current UK pricing).

Who it's for: Apple Watch owners who want guided class-based workouts at home and don't need to log specific sets and reps.

What's in the app

  • High-production trainer-led classes
  • Apple Watch metrics overlaid live during the class
  • Activity rings — Move, Exercise, Stand
  • "No equipment" classes available
  • Integration with Apple Music

Things to know

  • Requires an Apple Watch
  • iOS / iPadOS / tvOS only
  • You don't log specific sets and reps — the unit is "did you complete the class"
  • Doesn't track food

Which app matches what you actually want to do?

If you want strength, cardio and food in one diary

Our app, NutraSafe, was built for this. Workouts is a Pro feature (£3.99/month, iOS, monthly only) and unlocks set-and-rep logging, cardio entries, the rest timer, per-exercise history, HealthKit HR zones, and the four-week calendar — all sitting in the same diary as the food side, so calories in and calories out are one set of numbers, not two estimates from two apps. The free tier gives you the food scanner, the diary and reaction logging; Workouts itself is Pro.

If you only want to track strength and you handle food separately

Strong or Hevy. Both are mature, focused, and respected. Strong is the long-time standard; Hevy is the more recent polished alternative with a social side. Either covers gym logging cleanly. You'll run a second app for food.

If you want the app to plan your sessions for you

Fitbod. It picks the lifts, the order, the sets and the weights based on your equipment and recovery. Useful if you're not running your own programme. Again, no food side.

If you mostly count calories and only sometimes log cardio

MyFitnessPal. The food database is the largest in the category, and the cardio log is enough for "I went for a run" entries. Strength tracking isn't its thing — if lifting is your main training, you'll outgrow what it offers.

If you have an Apple Watch and want guided class workouts

Apple Fitness+. Different shape from everything else here — there's no set / rep logging, the metric is "did you complete the class". Built into the Apple ecosystem; the Watch is the controller.

How we put this comparison together

We're NutraSafe — we made one of the six apps on this list. So this isn't a neutral review; it's our description of what each app does, alongside ours. The descriptions above are drawn from each app's public UK App Store listing in May 2026 and our team's working knowledge of the category. We haven't run a controlled head-to-head test, and we deliberately don't quote specific competitor subscription prices in this article because they change — check each app's App Store listing for the current UK figure.

Where we've made a specific claim about NutraSafe (price, features, what's free vs Pro), it's drawn from our own app. The full free vs Pro tier breakdown lives on the pricing page. If you spot something we've got wrong on any app, the contact page reaches us and we'll fix it.

Workout tracker FAQs

Is there a UK workout app that also tracks food?

Yes — our app, NutraSafe. Strength sessions, cardio and food sit in the same diary so the calorie balance adds up in one place. NutraSafe Workouts is a Pro feature (£3.99/month, iOS). MyFitnessPal also covers both, but it's food-first; strength tracking is rudimentary and the workouts side is mostly manual cardio entries.

Do I need separate apps for workouts and food?

Not if you want the calorie balance to be real. Running two apps means copying numbers — or trusting that two different calorie-burn estimates agree. Strong, Hevy, Fitbod and Apple Fitness+ don't track food at all, so anyone using them for body-composition goals ends up with a separate food app.

What's the best free workout tracker in the UK?

Strong's free tier and Hevy's free tier both cover basic set-and-rep logging for the gym, and both run on iOS and Android. NutraSafe's free tier doesn't include Workouts — that's a Pro feature — but the free tier does include the barcode food scanner, the diary, and reaction logging.

Can I track strength training and cardio in one app?

NutraSafe handles both — strength logging (sets, reps, weight, rest timer, per-exercise history) and cardio distance entries sit alongside each other in the same workout, and that workout sits alongside your food log for the day. Strong and Hevy are strength-focused; cardio is light. MyFitnessPal is cardio-focused; strength is light.

Which workout tracker works with Apple Watch?

Strong and Hevy both have native Apple Watch apps. NutraSafe Workouts reads heart-rate data through HealthKit during a live session and shows HR-zone progress on the in-app workout screen. Apple Fitness+ requires an Apple Watch by design — the class metrics are driven by the Watch's sensors.

Should I use NutraSafe if I'm a serious lifter?

If you're powerlifting, doing programmed periodisation, or you care about bar / plate-loading calculators and 1RM tracking, Strong and Hevy have deeper strength-specific tooling and you'd probably want one of those. NutraSafe Workouts handles sets, reps, weight, cardio and rest with per-exercise history — it suits people who lift seriously but also want the food and calorie side in the same diary.

Why isn't Strava in this list?

Strava is a great app, but it's endurance / cardio focused — running, cycling, swimming — not gym tracking. If you want a strength tracker, Strong or Hevy is the comparable; if you want a UK app that handles both lifting and food, that's where we come in.

Try our app for yourself

Workouts in NutraSafe is a Pro feature alongside the AI Coach, AI meal scan, vitamin and mineral tracking against UK NRVs, allergen warning detail, and the full reaction-pattern analysis. NutraSafe Pro is £3.99/month, iOS, monthly only.

The free tier — food scanner, diary, reactions — is free to download. Try it for the food side first; if you want the workouts on top, Pro is one tap.

Get NutraSafe on the App Store

If you're tracking body-composition goals or pre-/post-event nutrition, the diary is something you can share with a coach, GP or dietitian — we're a tracking tool, not a medical service.
