Strong Workout Tracker: Gym Log, Exercise Journal

By Strong Fitness Ltd.

This app is only available on the App Store for iOS devices.


The most intuitive workout and exercise tracker for any fitness routine.

Throw out your notebook, Strong is the simplest and most intuitive workout tracker to get more from your workouts. Whether you want to gain strength or just stay healthy, join over 1 million people who have downloaded Strong to stay on track in the gym.

“I’d suggest downloading the “Strong” app before you return to the gym. It’s that good” - CNBC, June 2017

“with apps like Strong, working out feels more like a game” - The Verge, May 2017

“I have used nearly every logging app since the App Store launched. This is the best bar none”
“I use this every time I go to the gym and seriously couldn't train without it”
“Simple. Intuitive. Functional. Exactly what I was looking for.”
“This is bare bones and serious. Right on, and works perfectly... I wish I could give 10 stars.”
“It's by far the most intuitive and easy to use workout app I’ve used.”

Whether you’re a beginner or an experienced powerlifter, Strong provides everything you need to record your workouts as effortlessly and as quickly as possible. Unlike other fitness apps, Strong doesn’t bog you down with pictures and videos you don't need, and provide unnecessary functions you’d never use.

Strong is optimised for a progressive barbell routine such as Starting Strength or StrongLifts 5x5, but it is easily adaptable to any other routine of your choosing!

Customer Reviews

Good idea. So buggy.

I've been using Strong for the past couple of years, through many, many version. I like many of the features: the layout, the display of your entire routine on one screen, and ability to edit routines on the fly. But the bugs. Oh so many bugs. I don't think they've released one completely stable, bug-free version. The app freezes and hangs frequently -- numerous times during the course of a workout. The rest timer is completely unreliable. Sometimes it works, sometimes it doesn't. Sometimes you get notifications, other times it seems like the app just hung in the background and you won't know it until five minutes later when you think "Gosh, this seems like an awful long rest period!" I wish I could like the app more. I've been waiting for two years for solid, reliable version. But I'm so tired of dealing with bugs and an unreliable app, I'm going to start looking for a replacement.

Perfect no frills workout tracker

Replaced a decade's worth of notebooks. Allows me to track workouts easily - is very adaptable, i.e., it allows me to add and categorize any new exercise and the interface is simple to use to create / add / change / delete / copy workouts. Not to fancy but allows me to chart progress by conveniently showing last workout reps and weight as well as more in depth looks at progress by specific exercise. Also, happy that all capability was unlocked for only $6.99 vs many others that require subscriptions for premium features. Overall very pleased.

So easy!

This app has replaced my notebook journaling… Which is always sporadic because I forget my notebook and sometimes I just get bored writing things down because it's tedious… with this app, I have consistency and accuracy and progress with my workouts!!
I create my workouts on my iPhone and track them on my Apple Watch. Which means I don't have anything to carry around at the gym except my water bottle 😃
Then once in a while I export them into an Excel spreadsheet because I'm a spreadsheet geek. The app's reports are good too (I just love spreadsheets)
Love love love love love this app!
