There are more than 100,000 fitness apps on the Play Store alone. Over the years of testing them, I’ve learned to recognize glorified step counters from genuinely helpful apps that actually have something to offer.

Backed by Cybernews researchers, I went right in to answer these questions. So, stay with me as this Muscle Booster app review will dive into the tool’s personalized plans, exercises, calorie tracking, recovery, pricing, and more. By the end, you’ll have a complete overview of everything it offers and know if the Muscle Booster app is worth it for you.

Our methodology
When reviewing software, the Cybernews team and I apply a thorough evaluation process that’s backed by our years of experience. For today’s Muscle Booster review, that meant looking into the following aspects:
- Feature set (35%). We kicked things off by exploring the range of features Muscle Booster offers. Beyond that, we evaluated the quality and actual usability of said features.
- User experience (25%). Having a robust set of features doesn’t mean much if users are struggling to take advantage of them. That’s why we also paid attention to the app’s design, navigation, and ease of use.
- Accuracy and performance (20%). For a fitness app to be worth your while, the data it tracks must be factual and at least on par with the best tools available today. The time it takes to sync data from wearables, as well as app-to-app syncing, also matters.
- Value for money (15%). Regardless of how “revolutionary” an app’s features are, its price-to-performance ratio should still be within the range of other similar tools.
- User feedback (5%). Last but not least, we looked into verified Muscle Booster app reviews across well-known platforms to see how its users actually felt about it.
What is the Muscle Booster app?
Muscle Booster is a workout-focused tool with hundreds of exercises to choose from. Each also comes with detailed video instructions that make following the workout much easier. Yet, that’s not Muscle Booster’s core strength, as every other workout app offers the same thing.
The main appeal of Muscle Booster actually lies in its personalization approach. Its exercises adapt to your fitness levels, goals, available equipment, and home or gym setting.
The app’s workout plans are also designed to evolve with you as you progress. This way, you’ll be able to take full advantage, regardless of whether you’re a complete beginner or already know your way around exercising.
Now add challenges and motivational milestones into the mix. With these, you get a robust tool that not only helps you work out but also keeps you going even when you don’t feel like it.
Muscle Booster’s pros and cons in depth
Before we discuss Muscle Booster’s cost and offerings, I thought it best to first go over both the good and the bad about this muscle builder app.
Pricing of the Muscle Booster app
While there’s a lot to like about Muscle Booster, its cost will likely be the ultimate deciding factor, as it is for most users. So, is Muscle Booster free? If not, how much is the Muscle Booster app in terms of subscription costs?
Well, while there’s a free version, it’s not worth the hassle, as it lacks the tools that make Muscle Booster worth your while. Thus, this is a paid app with no free trial. It offers the following pricing options:
- 1-month subscription. $29.99
- 3-month subscription. $69.99
- 1-year subscription. $99.99
In the grand scheme of things, Muscle Booster sits on the premium end of the scale. But that’s not all, as you’ll also be offered guide-related add-ons for an additional fee. Refuse all of these offers initially, and you might get a limited-time deal with a massive discount.
Key Muscle Booster app offerings
Muscle Booster doesn’t just show you a workout and expect you to figure it out on your own. The app is jam-packed with features that help its workout adapt to your needs and make exercising easier and more enjoyable.
AI-powered workout customization
When you create a MuscleBooster.io account, the app leverages AI to create a custom workout plan that fits your exact fitness level, needs, and goals. That same AI engine also helps adapt the plan to your performance and feedback as you go along.
Home and gym options
While a gym offers a wide range of equipment and dedicated space to push your limits, it’s not the only location you can work out in. Muscle Booster also offers plans tailored to your living room, garage, or any other space in your home.
Offline mode
With Muscle Booster, you don’t need to stay in certain Wi-Fi-covered corners of your home or pay for mobile data to use it in the gym. The app lets you download workouts in advance and exercise in offline mode.
Integration with wearables
The Muscle Booster app integrates with both Google Fit and Apple HealthKit, allowing it to access data from other fitness tools and multiple wearables. These include Strava, Runkeeper, MyFitnessPal, as well as Wear OS and Apple Watch devices.
Nutrition and meal guidance
During the app’s setup, Muscle Booster will ask you whether you’d like to lose weight, gain muscle mass, improve fitness, enhance mobility, or just feel healthier. The app will then create a customized diet based on your answer to support your workouts.
Progress tracking tools
Muscle Booster keeps track of every step you take and workout you complete. It then compiles the data into easy-to-understand metrics, graphs, and achievements, to tell you exactly how you’re doing in the long run.
Exercise library
The Muscle Booster app is home to an enormous workout library with 2,000+ exercises to choose from. Each of these is paired with detailed textual and video instructions, so you can follow along at your own pace while ensuring proper form and technique.
Muscle Booster app: user reviews
Play Store and App Store ratings are a tell-tale sign of the app’s reputation, and Muscle Booster is doing quite well on both platforms. However, upon checking Muscle Booster reviews across Reddit, Quora, and Trustpilot, the situation changes for the worse.
One particular musclebooster.io review on Trustpilot tells a story of a user who wasn’t even aware they would be charged. Ask if the Muscle Booster app is worth it on Reddit, and you’ll see plenty of similar comments related to the company’s auto-renewals and refunds.
Overall, most of the negative feedback stems from shady business practices, while the app’s features are getting plenty of praise across the board.
Most commenters appreciate the app’s massive exercise library, stating they were able to find programs that fit their needs easily. Others mention its mobility exercises and how they’ve helped them reach their desired flexibility and energy levels.
All in all, user feedback is a mixed bag, with the features pushing the app’s rating up while the company’s unethical business practices bring it back down.
Muscle Booster vs competitors
Although features, pros, cons, and MuscleBooster.io reviews provide plenty of insights, it would also be beneficial to compare Muscle Booster to similar tools. Even a quick overview can help you solidify your decision or point you in another direction, so let’s see how Muscle Booster stacks up against competing apps.
