The first app offering true automatic exercise detection and tracking, using the motion of your Apple Watch. No need to manually log or write down sets at the gym anymore. Simply press "Start Workout", and begin moving. Train Fitness can detect over 130 unique exercise types, count your reps, and more!

The Train Fitness app works with your Apple Watch fitness to automatically track and record your exercises, count reps, and monitor performance. Our workout tracker uses the motion of your Apple Watch to automatically log the exercises and reps you are performing to enhance your strength training. Forget about your manual workout log, Train Fitness is the ultimate gym workout tracker.

We let you focus on working out, not rep counting. Apple Watch 4 or newer required.

We built Train Fitness because we too are lifters, gym enthusiasts, & fellow athletes, and we're tired of entering a workout log, manually. We believe that a gym workout tracker should be as easy as recording a run, and we’ll stop at nothing to get there. The Train Fitness App is an all-encompassing workout log app that tracks how you move and helps you achieve your strength training goals at the gym. Simply strap on your Apple Watch, and see the magic unfold.

Whether you want to gain strength, build muscle, lose weight fast, get shredded, or just log workouts at the gym, Train Fitness is the only hands-free workout tracker helping you achieve your goals.

Our AI-powered workout tracker works with the Apple Watch 4, 5, 6, 7, 8, 9, SE, Apple Watch Ultra, and Apple Watch Ultra 2. Unfortunately, due to CPU limitations with the Apple Watch 1, 2 and 3, we are unable to reliably run our application on these devices.

Weightlifting and gym log can now be saved to a profile, providing a valuable history of all your routines at the gym. Using an automatic gym workout tracker enables users to be completely hands-free and saves them time while working out.


Support for automatic tracking of 82 exercises, plus an additional 400+ manual exercises that can be logged using the app. Support for dumbbells, barbells, cable, and bodyweight exercises and routines.

Automatic rest timer starts as soon as you finish your set. Our Ai-powered workout tracker allows you to keep track of how long you have been resting using the handy rest timer to make sure you're reaching your strength training goals.

View breakdowns by muscle group, exercise, or time. Our workout tracker allows users to filter specific dates to see your strength training progress and understand how you are improving your bodybuilding or overall fitness.

We support gym exercises to hit biceps, triceps, chest, shoulders, back, legs, and core! Stop guessing what exercises to do or which workout tracker is easiest, know your goals and what workout log you need to follow to achieve them. We provide a seamless and easy way of sharing your workout tracker with your friends & community.

We are very serious about data. Train Fitness does not share your data with any third parties. All data is anonymized and never distributed. Period. Train Fitness uses HealthKit to export your Train Fitness activities into the Health app and to read heart rate and biometric data.

Finally, a workout app that’s easy and useful, AI is on point!

I’ve tried many weightlifting apps and you either get useful but tracking is not easy, or easy but too simplistic. When training, this app just lets you focus on working out. The AI is amazing, intuitively knowing what I performed and exactly how many. Sometimes I forget to confirm the set but found that it just logs it for you. You can go back and correct it if you want in case it calculates the wrong exercise or reps, but I often don’t have to. It pretty much gets it right. You can create a template but you can also just start a free form workout. Navigating on the watch for heart rate, volume, past sets and exercises, etc. is super easy (which I find not so common for many watch apps). Overall, it’s a terrific tracker that gives you what you need without manual fussing. Just open it up and it does the work for you, so you can focus on putting the work in.

best workout tracking app i’ve had

i have searched for so many workout tracking/logging apps but this is the best one i’ve found. the AI features with the apple watch being able to accurately track exactly what workout you’re doing and how many reps you did is actually unbelievable. I believe it doesn’t track leg workouts on machines (yet) but i’m hoping the developers will add support for that later. This app seems fairly new and it’s impressive how it has so many features already, i can’t wait for the developers to keep evolving the AI within the app and adding more support as the months go by.

Hi, thanks so much for the feedback, and glad to hear you're loving the app. We're working on machine leg exercises, hopefully coming very soon. Until then, enjoy the workouts!

all names i tried didnt work ,

Overall very good

Overall it does a very good job of automatically detecting exercises. It’s also nice to have because it gives you a rest timer, which prevents me from starting another set too quickly and not being recovered. My only issue with the app is that some of the exercises primary and secondary muscles are off, which throws off the given recovery stats. For example, dumbbell lateral raises say that the lats are a primary muscle, which does make any sense. Another example is that a wide grip rows say they target mostly lats, while in reality it’s mostly traps and rear delts. This isn’t a big issue but it’s just kinda weird in my opinion, because my lats have been at 30% recovery for a while now lol. In conclusion, this app is very helpful for tracking my number of reps and sets i do each session so i can make sure im implementing progressive overload, and i would recommend it to others.

Developer Response ,

Thank you for the feedback, really appreciate it. I've just gone ahead and updated our lat raises and wide grip rows accordingly, you're 100% correct on this! This update will be reflected in our next release.

We really appreciate the feedback. If you notice any other muscle groups off, feel free to shoot us an email at, and we can comp you Pro access to the app in exchange for your help fine tuning everything. Enjoy the workouts!
