Whether you work out at home or hit the gym, Muscle Booster's smart training algorithm will guide you through your sets, rep ranges, and rest between sets to help you achieve your training goals and find a faster way to fat loss.


Muscle Booster was developed specifically for men who care about their health and appearance and want to look and feel amazing. This app is a substitute for a personal trainer and will help you get in great shape, whether at home or the gym.


Set your goals: weight loss, muscle gain, or being more active
Select the zones that you want to work on: shoulders, chest, arms, back, belly, legs
Enter your personal data such as age, height, weight, fitness level, etc.


Our smart algorithm will suggest a personalized workout plan based on your goals and data – a combination of cardio, strength, and recovery exercises that will enable you to maximize your results.

Your basic plan is created for 60 days and displayed in your calendar. You can use it as a daily workout journal. Each week the workout plan will be updated according to your progress and feedback (if the previous workouts were too easy or too difficult for you).

With Muscle Booster, you’ll never be bored working out – you'll have access to a library of 200+ workouts, including muscle gain or weight-loss workouts, and gym or at-home routines with minimum or no equipment at all, like bodyweight or dumbbell home workouts.

Moreover, your workouts include convenient audio and video instructions, a weight-loss tracker, and a workout timer, all in one convenient health and fitness app.
There is also a recipe database included in the app (available in English only).


Muscle Booster integrates with HealthKit, so you can export nutrition and exercise data from Muscle Booster to HealthKit, as well as fitness data and weight and body measurements from HealthKit to Muscle Booster.

Transforming your body!

I’m just now starting the program. I just did my first morning session. It’s too early to say how I really feel about it. But I do like what I see so far of what the program offers. I am a pro athlete, a professional fighter. I’m so used to cutting weight and being ripped up for my next fight. Now I would like to focus on building up more muscles for my chest and legs. I fight as a junior middleweight and always have to cut weight for my fight, and most of the weight is water weight. So when I saw this program, I said to myself wow! they have everything you need to transform your physique to what you wanted to look like. I am also a trainer and have my own boxing gym, I say this app is good for everyone who wants to look good and get rid of the same fat that they carried around for so long. If you don’t know what to eat, they have a meal plan set up for you and his program. They tell you what the ingredients are. They also tell you how to go about cooking it. I recommend this app to any trainer and anyone who wants to transform their physique and look good about it!

A few frustrating gotchas

I never buy apps but I wanted to get a workout routine that was tuned to me and would progress as I do. I loved this app in the beginning, my muscles are more sore than any other workout I have done in the past. I’m a week in and my triceps are at their max so I figured my routine would move into my legs or abs, but it kept having me repeat the chest and arm strengthening. I found out today that the app is not tracking my progress, it doesn’t think I have been working out all week. For those that this is happening to, the developer requires you to hit the share button at the end of the workout to track that you completed it. This is annoying, I didn’t plan on posting to Facebook my workouts, the developer is trying to get free advertisement for a paid app. They need to add an option at the end to share or mark the workout complete. The good news is you can click on the share button, but cancel the actual Facebook post. This will mark your routine done but keep it private. I’m going to try that until my subscription is up and look for another app. Also, like others mention, the “contact us” button doesn’t work. I’m very suspicious of the integrity of this app. The workout have been great though so I hope they make some improvements. This app is too pricey for it not to “requires” free advertisement to Facebook. No one wants to see me post everyday I performed a daily routine for 7 minutes, how annoying I would be 😀

Starts Strong

I love this app. It provides a great workout routine that supplements my own. I felt immediate results and have seen them is a little as five days. I hope to continue on with the app, but that’s where I’ve run into trouble.

A glitch in one of the routines caused it to repeatedly crash on that routine. I decided to skip to the next day’s return until it could be resolved. The routine worked but wouldn’t log as compete. I tried various fixes like powering off the phone, etc. Then I tried to log back on … and the app would not let me log in, reset my password, or restore purchase (I tried them all). I was effectively locked out and my support inquiries all bounced back in email, indicating no one was likely to help. So, I decided to subscribe again until everything was resolved - but the app said my Apple email was invalid, after charging the subscription. I had to use a different email in order to make it work… so who knows what will happen in 90 days.

I was ready to refer this one to friends and my trainer, but now I’m holding off until these basic functions - email resets, restores, etc. are cleaned up. This should be a five star workout support program, but I have to give it a free until basic support and customer service are part of the package.
