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.

Use the Workout Player for audio tips, exercise instructions, information on targeted muscle groups, and a built-in workout/rest timer (Apple Watch compatible).
Join Challenges based on your profile. You’ll find everything from Morning Routines and Calisthenics Home Workouts to Fat Burning, Chair Workouts, Dumbbell Training, 6-Pack Programmes, and Injury Recovery.
Create custom plans that match your available equipment, including free weights, machines, resistance bands, or bodyweight setups.

I like the app a lot - simple for someone like me new to working out everyday (attempting...) I love how easy it is to use and the cost is pretty low! I use it when I travel or at home so the ease is great. They recently had an update, and no longer supported on my tablet which sucks - and the sound was difficult to find, since I mostly listen for the sounds. A few other glitches have been noticed but I am hoping they come out with a fix soon and support Google products to use as well!

I was looking for an app that allowed me to make my out workouts and that had recommendations or tips on performing the exercises! Which the app doesn't let you down at all in that aspect. The app even recommends an entire meal plan which is sweet. I only wish it also had a calorie counter and water intake tracker as well! That would really complete the experience! What say you?

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.
