Comments on Dr. Muscle AI Personal Trainer for Android

★★★★★ Frankenstein 12 · Nov 12, 2025
Exceptional! This is one of the best gym apps I have ever used. Its user-friendly with your daily programs workout already. It adopts your weights and reps as you go through each cycle. It's like having your own personal trainer with you at all times. The app can become addictive as you try to break your own records all the time. What I have learned is to be honest with yourself while you use the app and progress at your own speed and pace. Thank you for the good work, Dr Muscle and Team!
★★★★★ Michelle Russo (jimmington86) · Sep 6, 2023
I've been using this app for about 3 months and am really enjoying it. The AI takes all the guesswork out for me. I just do the prescribed workouts, and it updates the program for me each time. I got sick for a few weeks and took a break and was really pleased with how the app reloaded the workouts and helped me get my strength back sustainably. My main goal is weight loss, so I don't know how much muscle I have built, but I get stronger every week and am I making steady progress.
★★☆☆☆ Kevin Campbell · Mar 16, 2024
Thought I'd give it a try after reading reviews (including the creator bashing on the app I'm currently using and enjoying). Custom workout is a library of moves with no visual references to identify which to select. It asked me to guess how many of a stretch I could do in the warm-up, then logged it as my reps for that move when I gave a guess? Selecting available equipment is inadequate and again no visual aids. I'm sure there is an audience for this app, but it's not for me.
★★☆☆☆ Shaun Dustin · Apr 14, 2026
Intermediate lifter, so far there are things I like, but I’m frustrated by how Dr. Muscle handles HIIT in the analytics. A 4x40 sec HIIT session on a rowing machine is showing up as roughly 44,000 lb lifted, which makes the volume and workload metrics meaningless. It also makes me question the calories-burned estimate, because if HIIT is being accounted for in a way that clearly distorts one metric, it’s hard to trust the others.
★☆☆☆☆ Shawn · May 6, 2026
Way overpriced when there are apps out there that can do pretty much the same for literally about a quarter of the price. No nutritional help unless you pay even more money than the regular subscription price. The "AI" gives you a cookie cutter response that has nothing to do with what you asked it. This app isn't worth this price at all. It has potential, but not at that price. No app is worth over $70 / month. I wanted to like it, but I just can't justify paying that price.
★☆☆☆☆ Carla Davis · May 1, 2024
I want to like this but when trying to set up the app froze several different times. I had to start over each time and no matter how many times I start over I can't get a correct start weight. The app has a start weight, current weight, and goal weight. This is my first day using, so my start weight is my current weight, but the app didn't see it that way. It just picks a random start weight for me, so when I put my correct weight in, it has me gaining 80 pounds in 1 day!! No, thank you
★☆☆☆☆ Victor Flores · Aug 4, 2026
Pretty much the same 7 exercises ad infinitum. Going for a less lazy app.

Description by Dr. Carl Juneau PhD Written by the developer, not by AppBrain. Click to read.
“Stronger at 58 than I was at 27” -Bob McDermott. If you're looking for a workout routine to build muscle, muscle fitness and strength, we have something even better for you. This app gets you in shape fast using artificial intelligence. It's 59% faster, evidence-based, and always up to date.

Expert reviews:
"It makes working out very simple. All you do is answer a few questions about your unique situation and your goals, and then it generates a workout program for you. Then, when you do the workouts, you enter in your weights and it tells you how much weight and reps to do each and every workout, and it's based on the latest science of DUP."
— Jason Maxwell - Aerospace Engineer and fitness and nutrition author

"It's already a good design and has great workouts that will help you continually build muscle and break through plateaus, but they are constantly working to improve it based on customer feedback. The most important thing about this app is the customer service. Christelle and Carl are always available to assist you in anyway they can in a very timely manner, most of the time within an hour of submitting your question or issue. I would recommend this app to everyone serious about building muscle."
— David Fechter

A PERSONAL INVITATION
Hi, I'm Dr. Carl Juneau. In 2009, I got really sick and lost all my muscle mass. As a trainer, that was rough. Let's just say clients didn't really trust me, even with a PhD. I just didn't look the part.

I finally gained back 27.7 lbs of muscle, but that was tough. I kept failing. Now, I'm squeezing all I learned into this app. It's an intelligent, virtual coach or gym trainer that takes the guesswork out of training and gets you in shape fast. With your smart coach, every time you complete a set, your program updates automatically to match your progress, and speed up future progress.

It gets you in shape fast, like a personal trainer. But it's 59% faster, evidence-based, and always up to date. It automates almost everything, and guides you through the entire process. It's designed to make training a rewarding experience, simple, and fun again.
