Train Fitness is the first app to offer automatic exercise tracking, using only the motion of your Apple Watch. Trusted by 100,000+ weight lifters, Train Fitness is the future of AI + gym workouts.
Our application monitors the motion of your Apple Watch, tracking reps for over 470 unique exercise types – completely hands free! Our app will track push ups, bicep curls, 12 types of bench press, squats, deadlifts, and hundreds more! No more manually logging each set.
This automatic tracking is made possible by our patented Neural Kinetic Profiling, an advancement in AI that allows workout tracking using wrist motion.
Unsure what to do at the gym? Using the Train Fitness app, you can generate workouts based on your recovery, goals, and fitness data with the help of AI. Our Smart Weights system will recommend specific workout plans, exercises, sets, and weight… entirely customized to you! Let artificial intelligence build the best possible workout for you, and stop guessing what to do at the gym.
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.
Our application runs on the Apple Watch 4, 5, 6, 7, 8, 9, 10, SE, Apple Watch Ultra, and Apple Watch Ultra 2. Unfortunately, we do not support the Apple Watch 1, 2 and 3.

Aside from the fitness app built into the Apple Watch, this is my 3rd workout app. I initially got it because I used Apple health as my tracking hub and I felt like this app had better work out tracking than the others. After experiencing the auto exercise/rep recognition feature, I was really hooked. The app tracks muscle group recovery and the AI will create a routine for your workout that day based on what has recovered. Save that workout as a template, sync it to your Apple Watch and you can leave your phone at home! You can easily tweak the routine and adjust reps/weight after each set which was a big deal for me because I often rep to failure and want this tracked. Until recently, it lacked satisfactory cardio tracking, but as of the last update, it will import your cardio from Apple Health. Apple’s fitness app has great cardio functionality and tracking so now, so does TrainFitness. This new feature has worked great for me so far. Its exercise recognition is not always correct, but you can confirm exercise/reps/weight after each set and easily correct anything erroneous.

I almost never write reviews and if I ever do, they never get 5 stars. This app is extremely convenient and best of all, it’s free to use. You can upgrade to a premium service that will recommend workouts. However, since I have a background in weight lifting, I write my own workout programs. My Apple Watch automatically tracks each set, it’s not 100% accurate but I wouldn’t expect it to be. The workouts are easy to edit on the watch or in the app. I downloaded maybe half a dozen workout apps before this one. Each time they either needed a paid subscription or were inconvenient. If you are still reading this, stop, download this app, start your first workout. The rest is on you, commit to a schedule that works and share your results with others. PS- Proper exercise is only half the battle. Whatever goal you set for yourself is impossible if you don’t have the right diet or state of mind. (Something this app can’t provide)
Developer Response
Thanks for the feedback, really appreciate it. We have lots of big updates coming soon to make the experience even better. In the mean time, enjoy the workouts!
New update is terrible
00’s fan
The app was amazing, however the new update is terrible. Very glad I only use the free version because the changes make the app almost unusable. It no longer records your sets in groups based on exercise, it makes an individual block which makes it exceedingly more difficult to tell how many sets you’ve done if you are in the zone and focusing on the workout alone. It no longer recognizes supersets and struggles to differentiate exercises so it’s very likely you will get a new set of the same exercise you just did if doing supersets, and when you adjust it it changes both sets instead of the one. And there is an added voice to alert you at 1 minute 30 second rest which is meant to be helpful but it’s more annoying than anything. Especially since you will spend more time editing the workout trying to make it accurate than you should and will have you being told to workout in the middle of the edit, let alone spending enough time to take you out of the zone entirely. It gets a 2 star due to it still being free, however it is such a nuisance now I may quit using it entirely. A note to everyone developing apps if it isn’t broke, don’t “fix it” cause you may end up in a situation like this.
Developer Response
We really appreciate how thoughtful and detailed this is. You’re right — we changed how exercises and sets are organized, and this can definitely lead to some friction. Superset handling, automatic grouping, and the new voice rest timer should all be resolved at this time. We’re bringing back simpler, smarter ways to track progress with more user control. Updates are already underway. If you’re still running into any other issues, reach us anytime at hello@trainfitness.ai
The Ads I saw market this as a good Apple Watch experience, so…

My review will reflect the marketing. I think this is a lovely iPhone app for training, but the experience goes from super polished training app to “Your Apple Watch has disconnected” multiple times per set and sync issues. I don’t know if this one of the millions of cases of Apple Watch limitations making devs look bad, but I can only reflect on my experience. AWU + iPhone 17 pro, every time my watch goes to sleep, it disconnects from the iphone app. I tried many different things on how to “power through”, but continuing to use the watch, especially through supersets, it was not sending data to the phone correctly through all of the disconnections. It would jumble up progress on the watch. Thankfully the phone app doesn’t lose progress, but it’s not doing a great job of talking back to fix whatever the watch thinks is going on. Its sync status improves for single exercises, but it still sends “Your Apple Watch has disconnected” messages constantly. I’m only here providing feedback in hopes that your service improves over time, because the IDEA behind the app is great. I just don’t know that Apple allows you to be as ambitious as this app is trying to be. I would love for the Apple watch to be a functional tool.
Developer Response
Hi, thanks for the feedback. Apple does allow us to be this ambitious... and boy are we! Your Apple watch is on watchOS 26.2, but your phone is only on 26.1. This difference in operating systems is causing the connection issue. TO FIX: 1. Update iPhone to latest OS to match your watch2. Update your review to reflect the new working experience :) Hope this helps! Any other issues please don't hesitate to reach out via the in-app support chat.
