The Best 12 HIIT Workout Apps and The Secret to Their Success

Thinking about getting into the health and fitness technology space by building an app? Not a bad choice, with so many people trying to lose the weight they put on while working from home during the pandemic.

Health and fitness tech is a vast field with plenty of money to be made. Just like any other market, however, it’s absolutely vital to find your niche. Doing so requires you to study the trends, make note of what’s hot (but hopefully not a passing trend), and offer an app with unique features that your target market will love.

One niche worth exploring is apps that help exercise enthusiasts perform a type of training known as High-Interval Intensity Training (HIIT). A favorite among fitness enthusiasts for years now, the Worldwide Survey of Fitness Trends consistently ranks HIIT among the top 20 trends year after year. Why? Because it’s backed by science and delivers results.

What is High-Intensity Interval Training (HIIT)?

HIIT is a cardiovascular training system that involves alternating between bursts of intense effort and periods of rest or reduced effort. While there is no set formula for HIIT, it typically involves something along the lines of 60-seconds of intense effort that brings someone to 90% of their maximum heart rate, followed by 90-seconds of reduced effort or rest.

The HIIT App Market

If you explore Google Trends to evaluate searches for “HIIT” and “High-Intensity Interval Training” over the past five years, you’ll see how much attention these keywords get. Thanks to the increase of heart-rate monitors that come with Fitbit, Apple Watches, and other wearables, it’s easier than ever to do HIIT properly, and HIIT apps set fitness enthusiasts up for success. In fact, some of these apps even interface with wearables for an even better experience.

If mobile app development is something that interests you as a business opportunity, and HIIT workout apps strike you as a potential area of focus, then take a look at the following 12 HIIT workout apps. They represent some of the best HIIT workout apps in 2023, and figuring out what they did right can help you to emulate their success.
