About this app

Muscle Booster is a workout app designed for both men and women who want to build muscle, stay healthy, and feel great. Our Gym Workout Planner acts as a personal trainer alternative, helping you improve your physical fitness whether you're exercising at home or at the gym.

From muscle-building gym routines to calisthenics home workouts and weight loss programmes, Muscle Booster creates a personalised plan based on your goals and physical data. No matter your training location, the app’s smart algorithm guides you through sets, rep ranges, and rest intervals to help you hit your goals and track progress efficiently.

BEWARE WHEN YOU SUBSCRIBE! When you subscribe on the Play Store, the app also keeps your subscription saved in their system. So you have to subscribe on the play store AND their app! BUYER BEWARE! I canceled my subscription a while back because I found an app that's $45/year instead of $22/month, and just woke up to a $67 charge from this place I'm paying ~$200/year LESS for the other app. Do your research on your Home Workouts and what apps there are out there.

great app, the only thing I wished they had was the ability to say how sore your muscles are. I've had it where it will say a certain part of my body is at 100%, but it really is only at like 70%. I like that they show you what worked in the workout, but I wish that in the plan creating section, it would allow you to add that information. Besides that, it's an awesome app. It's really good for all lev3ls of working out!

I enjoy using this app. I find that it encourages me to exercise / workout every day or at least on schedule. I recently had a medical issue that prevented me from exercising for 4 weeks and the app let me pause my subscription for a month, extending the active period of my quarterly subscription. I thought this was very fair. I recommend the app, especially for those wanting to do body weight and other "at home" exercises / workouts.
