Best workout tracker apps in 2026

Musklr is the best workout tracker app in 2026 if you want to log sets fast on iPhone and Apple Watch. GymLog AI comes second if you also want to track what you eat: it logs your workouts and estimates calories and macros from a photo of your meal, on iPhone and Android.

A set takes two taps, the Apple Watch app shows your heart rate live, and there are no ads on any tier. Musklr is the cheapest way to get a full Apple Watch app, a live muscle heatmap and 2,000+ exercises in one app, at about $2.50 a month billed yearly.

Musklr is our app.

How were the best workout tracker apps of 2026 ranked?

We ranked seven apps by how fast you can log a set, how much the Apple Watch app does, the size of the exercise library, the muscle heatmap, ads and price, and we gave credit for tracking nutrition in the same app. Features were checked on 28 October 2026 against each app's App Store listing and its own website. Prices are regular App Store prices checked 28 October 2026. Where a vendor doesn't publish something, such as an exercise count, the table says so instead of guessing.

How do Musklr, GymLog AI, Hevy, Strong, Jefit, Alpha Progression and Fitbod compare?

"Not stated" means the vendor's own pages don't say (it may still work). "No" under nutrition means the App Store listing describes no food logging.

What are the best workout tracker apps in 2026?

Musklr

Musklr is built for one job: logging sets as fast as possible. A set takes two taps, with weight and reps filled in from last time. The Apple Watch app runs a whole workout from your wrist with live heart rate, and a Live Activity keeps the session on your iPhone Lock Screen. You get 2,000+ exercises with anatomy diagrams, and the live muscle heatmap lights up the muscles each set works while you log. Every set logs offline whether you sign in or not, and there are no ads on any tier. Musklr is the cheapest way to get a full Apple Watch app, a live muscle heatmap and 2,000+ exercises in one app, and no other app here has all three. Pro is $29.99 a year, about $2.50 a month, or $99.99 once, for unlimited routines, your full history and cloud sync, and the free version has no time limit.

GymLog AI

GymLog AI puts a workout log, a calorie counter and an AI coach in one app. Your last numbers sit on screen while you log, and the rest timer starts as soon as you tick off a set. With Pro, you photograph a meal and the app estimates its calories and macros, or you type or say what you ate, and the coach answers questions using the training you've logged. GymLog AI runs on iPhone and Android and is free to start, with Pro at $32.99 a year. It has no Apple Watch app, so if you want to log from your wrist, that's where Musklr is stronger.

Hevy

Hevy is a workout log with a big social side: its App Store listing counts 15M+ lifters, and you can follow friends and compare lifts in a feed. The Apple Watch app logs sets, runs rest timers and shows your heart rate without the phone, and workouts log offline. Pro adds Hevy Trainer, which builds a program for you, along with unlimited routines and your full history. Hevy shows muscle volume as charts and doesn't publish an exercise count, so there's no figure to set against Musklr's 2,000+.

Strong

Strong is a simple, quick logger, and its Apple Watch app logs workouts with or without your iPhone. The free version saves unlimited workouts but caps you at three custom routines, and Pro is sold by the month, by the year or once for life. Strong doesn't publish an exercise count. Musklr adds a Live Activity for the session on your iPhone Lock Screen and a muscle heatmap that updates live as you log.

Jefit

Jefit has 1,400+ exercises with video instructions, built-in programs, a muscle recovery chart and detailed progress charts. Its Apple Watch app syncs the workout with your iPhone and tracks heart rate. The free tier shows ads, which the paid Elite tier removes. Musklr has no ads on any tier, the free one included.

Alpha Progression

Alpha Progression plans your training for you. Pro builds a plan around your goal and equipment and suggests a weight and rep target before every set. The free version has no ads and needs no account, and the app works offline, with 795 exercises filmed in a real gym. It has no Apple Watch app, and Pro is sold by the month or the year, with no lifetime option.

Fitbod

Fitbod's algorithm builds each session around your recovery, from 1,000+ exercises with video. There's no permanent free tier, only a trial before you subscribe. With Musklr you follow a curated program, download one that another lifter has shared, or bring your own, and the free version has no time limit and no ads.

Musklr, if your priority is logging sets fast on iPhone and Apple Watch. A set takes two taps, it has 2,000+ exercises, a full Apple Watch app with live heart rate, a live muscle heatmap on iPhone, no ads on any tier, and it logs offline.

Which workout tracker apps work on Apple Watch?

Musklr has a full Apple Watch app: start a workout, log every set, run the rest timer and see your heart rate, all from your wrist and included free. Hevy and Strong also log full workouts on the watch, and Jefit and Fitbod have more limited watch apps. GymLog AI and Alpha Progression have no Apple Watch app.

Is there a workout tracker app with no ads?

Yes. Musklr has no ads on any tier, free or Pro. Of the seven apps we compared, Jefit shows ads on its free tier, and GymLog AI doesn't say either way. Check the App Store listing before you install, because that can change.

Which workout tracker app has the most exercises?

Musklr, with 2,000+. Of the apps that publish a number, Jefit follows with 1,400+, then Fitbod with 1,000+ and Alpha Progression with 795. Hevy, Strong and GymLog AI don't publish an exercise count, so we can't rank them.

Do workout tracker apps work offline at the gym?

Musklr does. It is offline-first, so every set logs with no signal and syncs later, signed in or not. Hevy, Strong and Alpha Progression also say they log offline. GymLog AI, Jefit and Fitbod don't say either way on their own pages, so check before you rely on one in a basement gym.

Which workout tracker app has a live muscle heatmap?

Musklr. The heatmap on your iPhone updates the moment you log a set, front and back, even when you log it on your Apple Watch, because the two stay in sync. Alpha Progression, Strong, Jefit and Fitbod also have muscle heatmap or recovery views, and Hevy shows muscle volume as charts.

Is there a free workout tracker app for iPhone?

Yes. Musklr is free for as long as you like, with no ads and no account needed, and every set logs offline. The free version covers one program with two workouts. Pro is optional, about $2.50 a month billed yearly, or $99.99 once if you'd rather not subscribe.
