Best Gym/Workout App for Apple Watch

Most Apple Watch apps are simple apps. They are basically extensions of your iPhone app, mirroring a small number of features.

This is not the case.

SmartGym is the most powerful Apple Watch app. It’s also completely independent from the iPhone, doesn’t require an internet connection to work, runs our Artificial Intelligence and Machine Learning locally, offers over 130 pre-made workouts, carefully created by Personal Trainers, and a lot more. And having all this on your wrist, is a game changer.

Unfortunately many people are actually afraid/embarrassed of going to the gym. Others might even go, but have no idea how to properly create a good routine (end up doing the same one for years, or doing routines that are actually bad and dangerous for them). Others don’t even bother, because they think this is not for them (either too hard or too complicated). And others would love to start working out from home, but don’t know how.

Another reason is mental health. This is becoming more and more important. And to many, the pandemic only made this issue more prominent. Many studies show how important exercises are to our mind. And how much working out can really help us.

In a world where most people are looking for ways to become healthier, having a tool like SmartGym becomes even more important and essential.

And to be honest, I don’t think that smartphones in general are the best solution to this problem. Think about it. They don’t track our heart rate or calories burn, they constantly distract us, we always need to find a place to put it, if you are a man you probably have pockets, but if you are a woman you need to find a way around it. Some put inside their waist, which might damage the phone, others use an armband, which is extremely uncomfortable, specially when using Plus sized iPhones. But the good news is that Apple has already solved this problem. To me, the Apple Watch is the ultimate Gym device. It’s extremely focused, always strapped to our wrist, comfortable to use and it also keeps track of our heart rate, calories and distance. That’s the reason why SmartGym was created entirely around the Apple Watch experience.

Completely Independent

That’s extremely liberating. Seriously, you need to try! Once you start working out with only your Watch, without any other device, there is no going back.

You don’t even need internet connection. SmartGym takes care of everything for you and will sync all your changes and workouts as soon as your Watch is back online.

Everything on Your Wrist

On the main screen you get a large button to start a workout session and track your calories, heart rate and distance, followed by all your routines.


Set's counter + Rest Timer with Haptic Feedback

One of the most common problem while working out is getting lost on which set we are currently at. To help with this, SmartGym’s timers are completely integrated with your sets. This means that every time you start to rest, it logs a set, showing you that you’ve just completed it. This way, you can get lost on our thoughts, while never forgetting which set you were.

Predictive Actions

This is great for two main reasons. First, it will guide the user to the next step, so users never get lost. Second, it's super quick to move to the next step. It's literally just one tap.

The end result is an extremely simple, elegant and transparent solution. The user never notices what is going on in the background. It just works.

Edit Your Exercises

Always On Display

With watchOS 8 and Series 5 or later, SmartGym will take full advantage of Apple Watch’s amazing Always On display.

Sometimes it’s really hard to rotate our wrist to turn the display on, while working out. And these are the times we need the most. We may need to check the remaining time of an exercise, like Plank; glance at our heart rates and calories while doing some pushups; check what’s the proper execution of an exercise by glancing at the animation; or just check our resting timer.

With watchOS 8, the display will be always on. Your information will be always up to date. And this changes everything.

Some amazing features SmartGym already had, becomes even more powerful. For example, the animation of how to perform an exercise. Or our predictive actions button, that also shows the user the next step on their workout. All these features will always work, no matter the position of your wrist.

All these screens take full advantage of the amazing Always On display. Timers, health data and even the exercise’s animation update in the background with the screen dimmed.

Artificial Intelligence + Machine Learning

Smart Trainer drastically reduces the knowledge and time required to create a routine, to just a few simple options. You can choose which equipment you have, which muscles you want to target, how long and how often you want to work out, your experience level and workout type. That’s it! SmartGym will create an entire workout for you, and will constantly give suggestions as they progress, like increasing the weight in a specific exercise, or replacing an entire exercise with another one.

From the main screen of the Apple Watch, just scroll down, tap one button and access the Smart Trainer setup. With just a few extra taps, you get an entire workout, personalized to you and based on the equipment you have available. All without the iPhone being nearby and without any internet connection. SmartGym’s entire AI Engine with CoreML, runs locally on the Watch itself.

Think about this for a moment. Right from your wrist, this tiny device can understand your choices, your health, your progress and create a complete and personalized workout for you!

130 Pre-Made Workouts, carefully created by professionals


But it can be a lot better. What if we could do what we want, without even tapping the device? That’s where Siri kicks in.

Without even opening the app, you can say: “Hey Siri, Start Today’s Workout on SmartGym”. And with your voice SmartGym will automatically launch, start the workout session and find the appropriate routine of the day (because it knows which day is today and which routine you should be doing), and put it right in front of you. All without even touching the device.

You could also specify the name of the routine, i.e: “Hey Siri, Start Routine A3 on SmartGym” or “Hey Siri, Start my Cardio Workout on SmartGym” and SmartGym will get the right routine for you.

And with watchOS 7+, SmartGym leverages the power of Siri Shortcuts on the Watch. Those same actions that can be done with your voice, can also be done from the Shortcuts app. But, even cooler than that, those same actions can become complications and can be launched from the Watch Face! This means users can have their routines as complications!

History and Measures

And with watchOS 6+, powered by SwiftUI, SmartGym has a gorgeous History View on the Apple Watch. You get all the information you need, right from your wrist. And we even added the amazing workout chart at the top!


Apple Watch Ultra

Health and Activity apps Integration

With SmartGym, you can start a Workout session that will keep track of your heart rates, distance and calories burned. And all your workouts will count towards your activity rings.

It’s really simple to start a workout session. You can tap Start Workout or use Siri (more on this below). Once you’re done, just tap the End button to stop the session. SmartGym will show you the summary of your session with your Activity Rings at the bottom.

User Reviews

Just a few reviews we recently got on the US App Store. From new mom that wanted to lose weight, to users who bought an Apple Watch just because of SmartGym, to Personal Trainers that can continue to manage their students remotely.
