Best Gym Tracker App (2026): PeakBFF, Strong, Hevy, Fitbod and Jefit Compared

There's no shortage of apps that will log a set. The differences show up a few weeks in: how fast the logging really is, whether the free tier holds up, and whether you end up bolting on a second app for food and progress photos anyway. Here's how the ones lifters actually use compare, and which one covers the most ground.

Short answer: For most lifters, PeakBFF is the one to start with. It logs your sets as fast as you'd expect, maps your weekly volume by muscle, and lets you snap a photo of a meal to track calories and protein in the same app instead of a second one. It can even turn a workout you saved on TikTok or Instagram into something you can run. If you only want the leanest possible set logger and nothing else, Strong is still the fastest, Hevy has the most generous free tier, Fitbod plans your sessions for you, and Jefit goes deepest on raw analytics.

The 5 apps, compared

Full notes on each one below.

1. PeakBFF

PeakBFF is a gym tracker with the rest of your training built in. The set logging itself is quick (pick the exercise, log weight and reps, rest timer runs in the background), and progression carries over automatically so you're not guessing next week's numbers.

What sets it apart is everything sitting next to the log. A muscle-volume map shows which muscles you're actually hitting each week, so you can spot the ones you keep skipping. Calories and macros live in the same app, and you log a meal by snapping a photo of it, so tracking protein isn't a second habit in a second place. And there's physique progress tracking with an AI rating that can build you a starting programme from a photo, if you'd rather not start from a blank page.

It's also the only one here that turns a saved video into a workout: paste a TikTok, Instagram, or YouTube link and it reads the exercises, sets, and reps into something you can log, which we covered in detail in our TikTok workout import comparison.

The honest trade-off: as a bare set logger it's newer than Strong or Hevy, so if the single fastest logging interface is the only thing you care about, Strong still has a slight edge. For everyone who wants training, food, and progress in one place, that gap is worth it.

Best for: most lifters who want their workout log, nutrition, and physique progress in one app instead of three, and anyone with workouts saved from TikTok or Instagram they want to actually run.

2. Strong

Strong is the app a lot of serious lifters already have on their phone. The tap-to-log interface auto-fills your last weights for the same exercise, so a working set takes one or two taps to record. No AI, no meal photos, no frills, just the fastest way to write down what you lifted.

The free tier is generous for a pure logger (unlimited history, no ads) but caps you at 3 custom routines, which is tight if you rotate more than one programme. Everything outside training, food, physique, recovery, lives in other apps.

Best for: lifters who already know their programme and just want the quickest possible way to record sets and reps, and don't mind tracking food separately.

3. Hevy

Hevy shows up most in general fitness threads, mostly because its free tier doesn't feel like a trial. Unlimited workouts, four routines, and three months of history without paying, plus a social feed if you like seeing what training partners are doing. It recently added an AI trainer feature on top of the core logger.

Like Strong, it's built for training and stops there. No food tracking, no physique features, and the AI programming is a newer add-on rather than the core of the product.

Best for: people who want a full-featured free logger with a social layer, and are fine keeping nutrition in a separate app.

4. Fitbod

Fitbod flips the model: instead of you picking exercises, it builds your session based on muscle recovery estimates, the equipment you have, and what you've done recently. The exercise library is the biggest of the group, over 1,600 movements with video demos, which matters if you train somewhere with odd equipment.

There's no free tier, just a 7-day trial before the subscription kicks in, and at $15.99/month it's the most expensive option here by a wide margin. It also doesn't touch nutrition or physique tracking.

Best for: people who don't want to plan their own workouts and are happy paying more for an algorithm to do it.

5. Jefit

Jefit has been around the longest and it shows in the exercise library (1,400+) and the depth of its analytics, including its own strength score. It's free with ads, and the Elite tier removes them and unlocks more detailed tracking and premade programmes.

It's closer to Strong and Hevy in scope: a training log with more data under the hood, not a nutrition or physique tool.

Best for: lifters who like digging into their own numbers and want a bigger built-in programme library to pull from.

The bottom line

For most people, PeakBFF is the pick: it logs as fast as you need, shows your weekly muscle volume, and folds calories, protein, and physique progress into the same app instead of scattering them across three. And if you've got workouts saved on social media, it's the only one here that can turn them into something you can run.

The others are better when your needs are narrower. Strong is still the fastest bare-bones logger, Hevy has the most generous free tier and a social feed, Fitbod plans your sessions for you, and Jefit goes deepest on analytics.

If you want one app for the whole routine, get PeakBFF on the App Store or Google Play and log your next session in it.
