Best Workout Tracker for iPhone in 2026

I've been building a workout tracker app since 2013. RepCount has been downloaded over 2 million times, has a 4.9-star rating on the US App Store, and was selected for Apple's "Apps We Love." I've read every single support email, responded to thousands of user reviews, and shipped hundreds of updates over 13 years.

So yeah — I'm biased. I think RepCount is the best workout tracker on the App Store. But I've spent 13 years in this space and I've used every competitor. So instead of pretending to be a neutral reviewer who just happens to pick my own app (you've seen those articles), I'm going to be upfront: I made RepCount because I couldn't find what I wanted. I'll tell you exactly where it shines, where others do things differently, and let you decide.

Quick Comparison

What Actually Matters in a Workout Tracker

Before comparing apps, let's talk about what matters — because most "best of" articles bury this under feature lists nobody reads.

A good workout tracker needs to do three things well:

1. Get out of your way between sets. If it takes more than a few seconds to log a set, you'll stop using it. You're sweaty, you're breathing hard, and your rest timer is running. The app needs to be fast. This is the single most important thing and the hardest thing to get right.

2. Show you what you did last time. Progressive overload is how you get stronger. You need to see that you squatted 100kg for 5 reps last Tuesday, so you can try 102.5kg or aim for 6 reps. If the app makes this hard to find, it's failing at its core job.

3. Stay out of your way the rest of the time. No nagging notifications begging you to come back. No social feeds to scroll through when you should be resting. No AI coach upselling you on a $40/month plan. Just your data, organized well, available when you need it.

Everything else is nice to have but secondary. If the core logging experience is bad, none of it matters.

RepCount: What I Built and Why

I started RepCount because I couldn't find an app in 2013 that was simple, fully customizable, and made it easy to track progression. Thirteen years later, those are still the three pillars.

What RepCount does well:

The logging experience is fast. You open your workout, see what you did last time pre-filled, adjust the weight or reps, and tap to save. It's a few seconds per set. I've obsessed over this flow for over a decade, removing taps and reducing friction wherever possible.

RepCount tracks personal records across every rep range, not just your 1RM. Your 5-rep max matters too. So does your 8-rep max. When you hit a new record at any rep range, you know about it.

The charts are detailed — volume over time, estimated 1RM trends, heaviest weight, total reps and sets. Premium users get hardware-accelerated charts that handle years of data smoothly, even if you've logged thousands of workouts.

It's a fully native app on both iOS and Android. Not a hybrid framework, not a web wrapper. A proper iOS app that behaves like an iOS app, and a proper Android app that behaves like an Android app. We stay current with each platform's latest design language — when Apple or Google ships a major update, RepCount feels right at home. Most competitors are slower to adopt platform design changes.

The free tier is generous. You can log unlimited workouts, create unlimited routines, and add as many custom exercises as you want. No ads. Premium adds advanced stats, supersets, and drop sets.

There's no social feed. You can't follow other lifters or share workouts. I know some people want this. If that's a priority for you, RepCount isn't the right choice.

There's no AI workout generator — yet. I'm watching the space closely, and the honest truth is that AI-generated workouts still aren't good enough for serious lifters. Most of what's out there produces generic programs that any experienced lifter would throw away after one session. When AI gets to the point where it can generate programming worth following, we'll add it. Until then, I refuse to ship a bad feature just to have the bullet point.

The exercise library is intentionally built around your exercises. From day one, RepCount was designed so that you build a library of the movements you actually do, named the way you think about them. We're expanding the library, but we're not going to dump 1,400 exercises on you and call it a feature. The core idea stays: it's your library, customizable to how you train, not a generic database you have to scroll past to find what you need.

The Competition: What They Do Well

Here's where I'll give credit where it's due. I use these apps, I study them, and several of them genuinely do things well.

Strong

Strong is probably the most well-known workout tracker out there. They've been around for ages, they've gotten great press from outlets like The Verge, CNET, and Lifehacker, and they have a large user base. It's a solid tracking option — no doubt about it. Like RepCount, Strong is focused on the core job of logging your lifts, and it does that well. They have an Apple Watch app, a plate calculator, a good exercise library, and progress charts.

They do some things differently — a done checkmark per set, inline timers — which some people prefer. Their workout templates are basic, similar to what RepCount and Hevy offer.

Where I think RepCount is better: Strong's free version limits you to 3 routines. RepCount gives you unlimited routines, unlimited workouts, and unlimited custom exercises on free. I find Strong's inline timer per set cluttered — it adds visual noise to the logging screen right when you want things simple and scannable. RepCount's analytics also go deeper: we track personal records across every rep range, not just your 1RM, with detailed volume and strength trend charts that handle years of data smoothly.

Hevy

Hevy has grown massively, claiming 10+ million users. They've built an impressive platform — the app itself, Apple Watch and Wear OS apps, a web version, and even a personal training platform. Their social features are the best in the category. If you want to follow friends, share workouts, and be part of a community, Hevy is the app for that.

Their free tier covers the basics, though it caps you at 4 routines and 7 custom exercises — which becomes a real limitation once you start building out your own exercise library.

Where I think RepCount is better: Hevy's social features are a double-edged sword. Some people find them motivating. Others find them distracting — you're in the gym to train, not scroll a feed. RepCount is deliberately focused on your training without the noise. Also worth noting: Hevy's free version limits you to 4 routines and just 7 custom exercises. That custom exercise cap is easy to overlook — even though they have a larger built-in library, if the exercise you do isn't in it, you're paying to add your own. RepCount gives you unlimited custom exercises and unlimited routines on free.

Hevy is built on React Native — a framework that lets developers build a single app that works on both iOS and Android. The app looks polished, but building for two platforms at once means compromises. It never feels quite as at home on iPhone as an app built specifically for iOS does.

JEFIT

JEFIT has the most comprehensive exercise library in the space — over 1,400 exercises with instructions and animations. If you're a beginner who wants guidance on form, or a bodybuilder who rotates through many exercise variations, this is a genuine advantage.

Where I think RepCount is better: JEFIT takes the kitchen-sink approach — workout tracker, exercise guide, social platform, program library — which means more time navigating menus and less time training. The interface has a lot going on, and it's not the fastest between sets. If you want a focused logging tool over a feature-packed platform, RepCount is the cleaner experience.

StrengthLog

StrengthLog is a fellow Swedish-built app, and their training programs are genuinely well-written — designed by actual coaches with real programming knowledge. If following a structured program is how you prefer to train, their library is worth a look. Their free tier is also notably generous — you get access to quite a lot without paying.

Where I think RepCount is better: StrengthLog packs in a lot — programs, articles, calculators, body measurements, muscle maps — and the interface reflects that. It can feel busy. It's built on Flutter, and the design lacks the refinement you see in a fully native app like RepCount. And while the free tier is generous, the premium price is steep: $16.99/month or $109/year — significantly more than most competitors. If you think you'll eventually want premium features, that's worth factoring in before you invest months of workout history into the app. RepCount takes the opposite approach: do the core job of logging and tracking exceptionally well, keep the experience clean, and keep the premium price accessible.

FitNotes (Android only)

FitNotes is completely free, no ads, no premium tier. It's a passion project maintained by a single developer, and I respect that enormously. If you're on Android and want something reliable without ever paying anything, FitNotes is excellent.

Where I think RepCount is better: FitNotes is Android-only with no cloud sync. RepCount is cross-platform with sync across devices. And RepCount's analytics go deeper if you want to analyze trends over time.

How to Choose

Here's my honest framework for picking a workout tracker:

Choose RepCount if you want a fast, no-nonsense tracker built by someone who actually lifts. If you value a clean interface, unlimited free logging, and native performance on both platforms. If you don't need social features or AI coaching and just want to get stronger.

Choose Strong if you want a well-known, focused tracker with an Apple Watch app and don't mind the limited free tier.

Choose Hevy if social features and community are important to your motivation. If you want to share workouts, follow friends, and be part of a fitness community within the app.

Choose JEFIT if you're a beginner who needs exercise guidance with video demonstrations, or a bodybuilder who rotates through many exercises and wants a massive pre-built library.

Choose StrengthLog if you want coach-written training programs and prefer an all-in-one platform, and are comfortable with the premium price. Their free tier is generous, but if you want the full experience, be aware that premium runs $16.99/month or $109/year.

Choose FitNotes if you're on Android, sure you'll never switch to iPhone, and want something completely free with zero strings attached. Just know the interface feels dated compared to modern alternatives.

The Things Nobody Tells You

A few things I've learned from 13 years in this space that you won't find in most comparison articles:

Your data is more valuable than any feature. Six months of consistent tracking tells you more about your training than any AI coach. A year of data is genuinely powerful. Pick an app you trust to stick around and keep your data safe — that history is irreplaceable.

The best app is the one you'll actually use. Features don't matter if the app frustrates you and you stop logging. Download two or three apps, use each one for a full training week, and keep the one that feels right. Don't overthink it.

Check the real cost of "free." Some apps have generous free tiers but very expensive premium plans. Others have limited free tiers but reasonable upgrade prices. Check both before committing — you don't want to invest months of workout history into an app where upgrading costs $109/year if others charge a fraction of that.

Native apps matter more than you think. If the app feels sluggish, if transitions are jerky, if it takes a beat too long to respond to a tap — that friction compounds over hundreds of sessions. Apps built with native frameworks (Swift for iOS, Kotlin for Android) are consistently faster and more responsive than cross-platform alternatives.

Try RepCount

I built RepCount because I wanted to get stronger and couldn't find the right tool. Thirteen years and two million downloads later, it's still the app I use every single day in the gym.

Download it for free on iOS or Android. Log some workouts. If it's not for you, no hard feelings — one of the other apps I mentioned above might be a better fit for how you train.

But I think you'll like it.

RepCount has been on the App Store since 2013 and has been featured in Apple's "Apps We Love." It's built by Siper Apps AB in Stockholm, Sweden.
