The 7 Best HIIT Workout Apps To Maximise Your Potential

In the modern day and age, technology is a part of every aspect of our lives, and the way we work out and keep fit is no exception.

From high tech fitness equipment and devices designed to monitor our vital signs to interactive phone applications, technology allows us to push our bodies to the max.

One such option that is becoming increasingly popular in recent years is workout apps, particularly those that focus on high intensity interval training (HIIT).

One of the best ways to lose weight and improve your cardio, HIIT offers great results, but takes a huge amount of discipline and dedication.

The idea behind HIIT workout apps is that they not only help to keep you motivated and on track, but also allow you to complete your HIIT workouts whenever and wherever you are.

This allows people from all walks of life to make the most of the benefits offered by HIIT.

Can a simple app that you download on a phone or tablet really help you to improve your health and fitness that much though?

Well, we will now take a look at the 7 best HIIT workout apps, to show you exactly the sort of results you can hope to achieve when using one.

What Is A HIIT Workout App?

A HIIT workout app is an application that can be used on a phone, tablet, and a number of other smart devices.

The idea of a HIIT workout app is to assist people involved in high intensity interval training.

Whether it be by tracking their results and progress, giving them tips and ideas for new workouts, or even just providing the ability to share their progress with friends, these apps aim to offer the necessary support and assistance to help you reach your potential and achieve your goals.

While many can be used across all such devices, there are also HIIT workout apps that are exclusive to either Apple or Android.

Plus, there are paid and free options available, as well as apps designed specifically with certain groups in mind, such as women, personal trainers, or competitive athletes.

What Are The Benefits Of Using A HIIT Workout App?

There have been numerous studies conducted that have looked at the efficacy of home workout apps.

They have examined not only how these apps alter the intensity and results of your home workouts, but also how these workouts compare to those in a traditional gym environment.

In one study, researchers found that mobile exercise applications can be effective, as they encourage people to work out at times when they otherwise wouldn’t.

The results showed a notable increase in exercise activity during leisure time among the study participants. 

This can be down to a couple of reasons. Firstly, these apps allow users to exercise at their own pace and ability, from the comfort of their own home.

This not only removes the need for a gym membership and reduces the effort it takes to prepare for a workout, but also allows you to train in a space where you feel safe and comfortable. 

The other reason is the interactivity or motivation provided by the app.

Some options will simply show you how you have been progressing, painting a clear picture of your results, while others can even be connected to social media, where you can share your progress or compete with friends.

Either way, these methods of shining a light on your results instils a new level of drive, determination, and commitment, which makes people want to work out harder and more frequently, so they can achieve results better than they could before.

The Best HIIT Workout Apps

We will now take a closer look at what we believe to be the 7 best HIIT workout apps currently available.

These will include options designed for people of all different ability and experience levels, as well as both free and paid apps.

This should ensure anyone who has decided to use a HIIT workout app for themselves will be able to find the one that perfectly matches their own wants and needs.

1. FitBod

FitBod was designed to provide more personalised workouts that are tailored toward your own individual goals.

Settings allow you to easily select which muscles and body parts will be targeted during any given workout and determine exactly how they will be worked. 

The app tracks all of your past workouts to not only see how you train and adapt but also to carefully gauge how you are progressing. This allows it to make suggestions on areas that need to be improved, as well as new options to further help you enhance results.

Videos are provided to ensure you get a thorough view of how each exercise works, while detailed instructions are also provided.

There are even links to sections on things like diet and supplements, to help you tailor your behaviour outside of your workouts, to maximise your physical potential.

FitBod is a premium service that requires a subscription of £12.99 per month of $79.99 per year to gain access to its full range of features.

However, it is free to get started, as the company offers a trial, allowing you to see what the app has to offer before you commit to buying. 

One of the more popular HIIT workout apps available, it has already been downloaded more than 5 million times and over 400 million workout sessions have been logged. 

The company even offers branded apparel and fitness equipment, to help you power through all of your workouts. Many of their products even come with discounts for full subscribers.


  • Allows you to target specific muscles and body parts
  • Tracks your past workouts to help you progress
  • Detailed videos and descriptions of each exercise are included
  • Provides support on things like diet
  • Offers a free trial so you can test out the app


  • Access to the full service requires an expensive paid subscription

2. Freeletics

The Freeletics system is designed to function as your own personal health and fitness coach that you carry around with you.

It has sections devoted to both exercise and nutrition, to help users reach their goals as quickly as possible.

In the exercise portion of the service, you will have access to over 900 different workouts, which range in length from 10 to 30 minutes and have options suitable for everyone from complete beginners to experienced athletes.

The workouts can either be manually selected or chosen for you by the app when you input data such as you age, gender, weight, and the areas you hope to target.

All workouts are explained in detail with incredibly clear instructions and videos, while access to real trainers is available 24/7.

In the nutrition side, you have numerous articles dedicated to how to build a successful diet to supplement your training, based on your training and physical attributes, while access to experienced professionals is again provided.

Perhaps the most popular facility of the Freeletics service though, and why it ranks as the number 1 HIIT workout app in Europe, is due to its incredible level of interactivity with social media.

Users can quickly post everything from session results and workout routines to progress pics using the same easy to understand user interface that is present throughout the entire service. This allows you to have your friends, family, and other users keep you accountable and share in your success.

Despite all of this, a large portion of the Freeletics service is free to use. However, there are some in app purchases and elements hidden behind paywalls as well.


  • Covers both exercise and nutrition
  • Incredible level of interactivity with social media platforms
  • Provides more than 900 different exercise routines
  • Offers 24/7 access to professional trainers and coaches
  • Workouts can be manually selected or chosen for you based on your ability and goals


  • Certain elements of the system are locked behind paywalls

3. HIIT Interval Training Timer

The HIIT Interval Training Timer is the perfect app for people who already know what they are doing and simply want something to help with tracking their performance.

While quite basic compared to some of its competitors, it is one of the most customisable HIIT workout apps available.

When you first download the app, you will be taken to a set-up screen with an incredibly straightforward user interface, which allows you to set up preferences which include a choice of voice.

You can easily create a custom timer with the app, to facilitate the specific workouts that you are going to perform, while aspects such as the number of sets and rest times can also be added. There is even a feature to adjust or skip parts of the session mid workout.

Once the workout is complete, you can then save it as a pre-set, to allow it to be completed again in the future.

Other pre-sets that come loaded on the app include workouts focusing on things like fat loss or Tabata training.

Among the other features of the HIIT Interval Training Timer, you will find a volume selector that allows you to control the volume of the app and your music independently of one another, as well as a step counter.

A vibrate mode and warning clicks allow you to keep track of your session without always following the vocal cues, while the ability to connect with social media accounts on Facebook and Twitter lets you share your results and experiences with friends, family, and other users.


  • Features an incredible range of personalisation options
  • Comes with a choice of voices, as well as a silent “vibration mode”
  • Past workouts can be saved to be completed again
  • Incredibly straightforward user interface
  • Free to use and share results on social media


  • May be a little too basic for less experienced users who require more assistance

4. J&J Official 7 Minute Workout

Created by Johnson & Johnson, the J&J 7 Minute Workout app has been designed by an expert in exercise physiology, to allow you to work out smarter than ever before, optimising your sessions and eliminating any wasted time.

A range of 72 exercises and 22 additional workouts creates more than 1000 different combinations, to ensure that your sessions are always fresh and exciting and keep your motivation levels as high as possible.

There are also warmups included, to make sure you stay safe while working out, as well as an alarm that lets you know when you have gone too long between sessions.

Each of the dynamic workouts features carefully chosen music, instructions and videos created by highly qualified exercise professionals, and an easy to use timer, to ensure every second of your session is planned to perfection.

You can select the workouts manually or enter biometric data and goals, to allow the app to select the best routine for you.

Apple users can even sync it up with their Apple Health app, to save them time and allow the results to be shared between the two.

Workouts can then be saved to repeat at a later date and see how you compare, while results can be tracked to show your progression and even shared with friends, either to provide extra motivation and encouragement or to help you build a little bit of healthy competition.

Compatible with both Apple and Android devices, new functionality has even been added to ensure the app is optimised for use on the Apple Watch, to ensure it truly can be used anywhere, at any time, by anyone.

The only potential drawback is that, while the J&J 7 Minute Workout app is free to download and use, the full version does require a subscription fee of $10 per month, which is a little steeper than many of the other options on the market.


  • Incredible level of connectivity with numerous different devices
  • Alarms and warmups help to keep you safe and motivated
  • Incredible range of different exercise routines
  • Designed and instructed by highly qualified exercise professionals
  • Sessions are carefully planned based on a user’s own personal data

It utilises more than 180 different movements, including those that rely on bodyweight, barbells, dumbbells, kettlebells, and more.

Workouts balancing strength and conditioning with cardio, including warmups and cool downs, are designed to fit your personal schedule and lifestyle.

Each comes with detailed instructions or videos, plus recommendations on the weights you should be using, based on your physical ability and data.

Heart rate tracking and integrated timers ensure workouts run smoothly throughout, while data tracking provides clear and concise evidence of your progress, with customer assistants constantly available to explain anything you may not understand.

Based on these results and your physical statistics, the app will also suggest the calories and macros you should be consuming in order to achieve maximum results.

For more detailed assistance, Keelo even provides access to highly skilled personal trainers and nutritionists.

The daily tracking system is a great way to keep people exercising every day. Meanwhile, Keelo also uses a reward system to motivate users, where things such as branded fitness gear, Amazon gift cards, and other special prizes are up for grabs for the best performers every month.

Optimised for Android, Apple, and even the Apple Watch, Keelo can easily be used by everyone, no matter the time, place, or device they are using.

The free version makes Keelo accessible for all, however, the $15 monthly fee for the premium version is one of the highest we have seen.


  • Unrivalled level of support from customer assistants, nutritionists, and personal trainers
  • Multiple reward systems are perfect for users who lack motivation
  • Optimised for use on a wide range of different devices and operating systems
  • Workouts combine elements of both strength and conditioning and cardio

Are There Any Drawbacks To Using HIIT Workout Apps?

The main drawback to using HIIT workout apps is the fact that they encourage people to work out from home.

While this may be beneficial or convenient for a lot of people, it can be problematic for others, particularly those who lack motivation. 

When a person lacks motivation, they may not be as willing to get ready and work out.

While there are features built into many of the apps specifically designed to tackle this issue, computers can only do so much.

No matter what steps to providing motivation an app may offer, it will pale in comparison to visiting a fitness center or gym for most people.

These facilities provide motivation in the form of social interaction and personal trainers, adding that human element that simply isn’t possible at home on your own with an app.

Another issue that is sometimes mentioned when looking at the drawbacks to using HIIT workout apps and training at home is personalisation.

With no personal trainer or other people around to check their form or offer dedicated insights on how they are progressing, it can be harder to determine the best plan for people to move forward.

Finally, for many people, once they have become used to training at home, going back to a traditional gym can be challenging.

If you have enough space and equipment at home to be able to progress continuously, this won’t be an issue.

However, most people don’t have huge amounts of equipment and free space in their home to train with.

This can often mean people settle for using what they have available, which leads to less intense and effective workouts and notably reduced results.

Do You Need Any Other Equipment To Use A HIIT Workout APP?

The only equipment you are guaranteed to require to use a HIIT workout app is a compatible device.

This can be any smart device, from a phone or tablet to a smart TV. However, you need to be sure its operating system, i.e. Apple or Android, is compatible with the app you are planning to use.

Many of the workouts completed in HIIT sessions will consist entirely of bodyweight exercises, so additional pieces of fitness equipment aren’t necessarily a requirement.

That said, a small amount of equipment, such as a set of dumbbells, a kettlebell, and an exercise mat, are a good investment if you are planning to work out at home, as you won’t be limited on the number of the routines on the app that you are able to follow.

Should You Pay For A HIIT Workout App?

Whether or not you should pay for a HIIT workout app depends entirely on what you are hoping to achieve from the app, the style of training you prefer to complete, where you generally like to train, and how dedicated you are going to be to following your training plan.

As there are countless free HIIT workout apps available, as well as free versions of paid apps, it will definitely be worth trying these before you decide to invest in a paid app or pay for a subscription for most people.

This will give you a clear insight into the sort of things you can expect from these types of apps and help you to determine if they are right for you.

It is important to note, however, that free apps can be quite basic when it comes to the features and facilities they offer, while the free versions of paid apps can often be very restrictive in terms of how much of the full app they give you access to.

If you find that there are too many limitations, look at what the paid plans and apps offer and weigh up if you feel they provide enough benefits to make them worthwhile. 

Some of the paid apps will even give you a free trial period to test out the premium features, so you know exactly what you will be getting, before you part with your hard earned money. 

However, if you are someone who is completely committed to their training, is striving to achieve the very best results, and finds that the features of a HIIT workout app are helping them to progress at a faster rate, then it is something that is definitely worth investing in.

How To Start Using A HIIT Workout App?

When you decide to take the plunge and try out a HIIT workout app, the first step is to consider the platforms supported by the app.

With some being locked to either Android or Apple, you don’t want to waste time looking at one which isn’t compatible with any of the devices you own.

Next, you need to determine whether or not you are willing to pay for an app. If you aren’t, this will narrow your search purely to free apps or free versions of premium apps.

You will then need to look closer at each app’s functionality.

Selecting one that offers all of the features and benefits you are looking for is imperative to its success, and there are a wide range of different choices.

Some apps are designed to time your workouts and track your progress, while others provide video content to give you more options and ideas, help you to see the exercises in action, and allow you to share your results with friends and family or on social media. 

At this point, you should now have singled out the app that is most suitable for you. The next step is to download the app onto the platform or device on which you plan to use it. You will then need to set up your account and, if you have chosen a paid app, select a plan and pay the fee.

You should now be ready to go and can start looking at how the app works and begin utilising the functions to help with your workouts.
