Fitness app sprawl is the default state of every gym-goer's phone. There's the workout tracker you tried for two weeks. The running app from when you signed up for that 10K. The nutrition tracker you abandoned around day three of logging. The wearable's companion app you never opened. The meditation app from the new-year resolution. Each one was the right answer to a real question. And now they all just sit there, eating storage, sending notifications, and pretending to be useful.
The fix is fewer apps, each one chosen for a specific job. All-in-one super apps tend to be good at nothing. Pick five narrow ones that do their work and stay out of the way. These are the five we'd keep.
1. Fitness Vault: strength and video-based training
Use it for: Importing YouTube / TikTok / Instagram / Facebook workouts, building programmes from them, logging sets and reps with the video on the same screen.
Cost: Core free — manual tagging, programmes, logging, stats; AI auto-tagging on Premium · Platforms: iOS, Android (private beta)
Full disclosure: this is our app, and we're putting it first because it sits in the spot most people open every day: strength training, home workouts, video-led routines. It exists because every other workout tracker on the market was built around barbells and named exercises, which is fine if you have a coach writing your programme but useless if your coach is a YouTube channel.
The flow is one move: hit share on a workout video, send it to Fitness Vault, tag it (chest, dumbbell, intermediate, whatever), drop it into a programme. When you train, the video plays at the top of the screen and the set/rep logger sits underneath. No tab-switching, no notes-app workaround, no "watch on YouTube, log in Strong" juggling act.
Outside the strength + video lane we're deliberately weak. Strong and Hevy do barbell programmes better. Strava does runs. MyFitnessPal does food. That's why this list has four other apps on it.

Verdict: The one we built because nobody else had.
2. Strava: running and cycling
Use it for: GPS-tracked runs, rides, hikes, swims. Routes, segments, the social feed.
Cost: Free tier covers most people · Premium £8.99/month or £54.99/year (as of mid-2026) · Platforms: iOS, Android
Strava has been the default for endurance athletes for over a decade and that's not an accident. The GPS tracking is accurate, the route layer is genuinely useful, and segments (the bit where your time on a specific stretch of road or trail gets compared against everyone else who's ever run it) is the single best motivational mechanic any fitness app has ever shipped. It turns a solo run into a leaderboard.
Honest take on the paid tier: most casual runners and cyclists never hit a wall worth £8.99 a month. The free version covers tracking, history, the feed, and basic stats. Pay if you race, train against specific segments, or want the route planner. Otherwise the free tier is plenty.
Verdict: Still the king for outdoor cardio. Use the free tier unless you actually compete.
3. MyFitnessPal: nutrition tracking
Use it for: Calorie and macro logging, barcode scanning, food diary.
Cost: Free (with ads) · Premium from ~£5.42/month (£64.99/year), as of mid-2026 · Platforms: iOS, Android
MyFitnessPal's only real moat is the food database: one of the largest of any app, an actually-fast barcode scanner, and decades of user-contributed restaurant items. Every challenger has tried to beat it on UX. None of them have beaten it on coverage. And when you're standing in a supermarket trying to log a snack you bought five minutes ago, coverage is the only thing that matters.
Honest take: the app has gotten heavier over the years. Ads are aggressive on the free tier, the home screen is busier than it needs to be, and the premium pitch is constant. But nothing else with a comparable database has emerged. So you put up with it, log your food, and close the app.
Verdict: Showing its age, still the right answer.
4. Apple Health / Google Fit: the plumbing
Use it for: Aggregating step counts, workouts, sleep, and heart-rate data from everything else into one place.
Cost: Free, pre-installed · Platforms: iOS (Apple Health), Android (Google Fit / Health Connect)
These aren't apps you actually open. They're plumbing. The job is to sit in the background, pull data in from your watch and the other four apps on this list, and have it ready when you eventually want to look at a year of training in one chart. You set permissions once and forget about them.
Honest take: don't skip this step. The first time you switch tracker apps and realise none of your history came with you because you never connected it to Health Connect, you'll wish you had.
Verdict: Already on your phone. Turn it on once.
5. Sleep Cycle: recovery (or your watch)
Use it for: Phone-based sleep tracking and a smart alarm that wakes you in light sleep.
Cost: 60-day free trial; paid price not publicly listed · Platforms: iOS, Android
Sleep is the most under-tracked half of training. You can programme the perfect week, eat the right macros, and still go nowhere if you're running on six bad hours a night. Sleep Cycle uses your phone's mic and accelerometer to score sleep and time your alarm to a light phase, so the morning doesn't feel like you've been hit by a bus.
Honest take: skip this one if you wear an Apple Watch, Garmin, Fitbit or Whoop overnight. The data's already there and it's usually more accurate. Sleep Cycle is for people who don't want a wearable on their wrist while they sleep.
Verdict: Optional if you wear a tracker to bed. Underrated if you don't.
Side-by-side
| App | Job | Free Tier | Pay If |
|---|---|---|---|
| Fitness Vault | Video-based strength training | Manual tagging, programmes, logging, stats | You want AI auto-tagging |
| Strava | Running, cycling, GPS-tracked cardio | Most users never need more | You actually race or chase segments |
| MyFitnessPal | Food and macro logging | Logging, scanning, basic reports | You hate the ads enough |
| Apple Health / Google Fit | Background plumbing | Everything | Never. It's the OS. |
| Sleep Cycle | Phone-based sleep tracking | 60-day free trial | You don't already wear a tracker |
What we left off (and why)
- Strong / Hevy / Jefit. Good barbell loggers. They just overlap with Fitness Vault for most home and video-based trainers. Pick one.
- Nike Training Club / Peloton App. Good content, closed gardens. You can't bring your saved videos in or take your training history out.
- Calm / Headspace. Worth using if meditation matters to you, though they sit closer to wellness than to fitness training. Lumping them in dilutes the list.
- Whoop / Oura / Garmin Connect. These live with the wearable. If you own the device, you're using its app already.
The bottom line
Five apps. One for strength and video-based training, one for outdoor cardio, one for food, one for the data plumbing underneath, and one for sleep (even that last one's optional). Delete the rest. Most of them weren't earning the space anyway.
If your training already lives on YouTube, TikTok, Instagram or Facebook, the workout-tracker spot in this list is the one we built. Here's why →
