## Built With Science+ Reviews in United States

### ***** "Excellent"
Life-changing. Kudos to Jeremy and team. Wife and I have loved the app and have lost a ton of weight so far while building muscle. 

Suggestion : add blue progression arrows to Apple Watch so I don’t have to go to my phone to see what to adjust for my next set.
-- AzianStang, 2026-09-13

### *---- "Gained 4lbs of fat and lost 1lb of muscle in my first 2 months"
I didn’t keep to the calorie guidelines but hit my protein goal and exceeded most days, was on calorie surplus and was consistent with workouts and effort level, and after 2months my dexa scans say I gained 4 lbs of fat and lost 1lb of muscle. The only change I made over the last two months was downloading this app
-- grumpymat, 2026-09-13

### ***** "Great program"
In my experience the program is done well and if you stick with it you will see results.
-- 15Wanie, 2026-09-12

### ***** "Trust the process!!"
I was skeptical at first, but I cannot imagine a day without this app. It offers the right guidance and information I need to get through my meals and exercises. I do wish it would be more affordable so that more people can utilize this great and essential tool in their daily lives
-- Hein117, 2026-09-10

### ****- "Excellent but could use improvement"
This app might be the only one in the entire market that offers an all-in-one, comprehensive feature of nutrition tracking and a workout program. I’ve been following BWS for an extended period and it’s amazing how far the company has come. 

Some improvements:

1. Inability to view exercises without going into the actual workout. Also, inability to view the exercise before swapping my current exercise is also inconvenient. It would be nice just to have a section to view each individual exercise. This is probably the biggest improvement needed 
2. The AI is still in beta stage, but frequently analyzes my personal fitness data incorrectly.
-- HaydenChoi1993, 2026-09-09

### ***** "Great all in one app"
This app is great for fitness, weight training and nutrition tracking all in one place. The nutrition component alone is better than all other apps I’ve tried. The weight training has videos and tracking so you can remember where you were and see progress. AI component is excellent for providing tips along the way - I use it all the time.
-- PKB57, 2026-09-08

### ***** "Great workouts"
Love the variety of weight training exercises!  Also program is helping me develop my understanding of nutrition.
-- g1958g, 2026-09-07

### ***** "Great app overall"
Overall, this is a great app. I love that I can track my diet and exercise all in one place and for the most part the exercise programs are solid with clear instructions on how to perform each exercise.  The integrated AI system is pretty fun as well.  

My only gripe is that there isn’t enough third-party app integration.  I want to be able to work with Garmin, Strava, Apple…etc and have those work towards my weekly progress without having to manually, add it all in after the fact.  

Not enough of an issue to dock it to four stars, but maybe like a 4 1/2.
-- Ozdincook, 2026-09-05

### ***** "Good Work"
This is only day one but I’m going to trust the process.
-- jeff i am, 2026-09-02

### ***** "Sharing machines"
Hard to superset rotating exercises as weights and benches were in use by others. Limited cable. Machine. Otherwise workout was thorough 
And feels good.
-- Kiwi2013-2, 2026-09-01

### ***** "Must have app"
I love this app
-- caraletterina, 2026-08-31

### ***** "Easy to follow and use nutrition and workouts"
For someone who hates AI and that type of technology, I sure do appreciate how simple it has made logging my calories and meals. I have only done my first workout, but I also really love the variety and machines I use for a total body workout. I feel utterly amazing after the first day. And I’m also very surprised by the amount of food I can eat and the ease of hitting macros I have in the nutrition portion of it. I can’t wait to see the results in 6 to 8 weeks.
-- Metz'D Up, 2026-08-31

### ***** "Got me back into a gym routine after almost a decade"
I never leave reviews about apps. Let’s just start there. But after the first few weeks of using this app, I knew I would leave a review. I have been following Jeremy on YouTube for several years and have recommended his channel to countless people, including my students when I used to teach a college weight training class. His content is foundational, accessible, grounded in science and practical. No BS just to get likes. I really respect that about his work. Now the app, I had known about it for a while, but was not ready to make the financial commitment for what I thought would be another fitness app or membership ship I would pay for and never use. I have even bought Jeremy’s online programs in the past and didn’t stick to them. Then a guy I was dating was using the app for his own fitness journey and I decided to give it a try to get back on my own fitness journey. At first, I wasn’t sure about it, but after a couple months of casually looking at it, the workouts and kinda plan meals, I decided to actually go in and do a workout with the goal of just getting through it, no PRs. From that first workout, I knew this app was different. I struggle with striking a balance between easing into workouts but also wanting to feel like I did something. The Beginner 2 workouts designed for me struck the perfect balance. On top of that, you can easily swap exercises with recommendations to get similar effects, it tracks your weight and reps and provides recommendations for progressive overload..and even the Jeremy AI has been incredibly useful!! I had injuries, painful periods and even a hectic school year approaching and Jeremy AI helped me game plan for it all. I have now recommended this app to all my friends. I am grateful for the app and so happy I finally gave it a chance! I am hopeful to give an update a year from now after a trip to Belize, which was the main motivation for finally giving the app a try. Thank you Jeremy and Built With Science!!

### ***** "Program"
Very well laid out app, great workouts, and very informative! Nutrition section is great, easy to keep track!
-- Mikesull 71, 2026-08-30

### ***** "Built with Science"
This really is a great program and is helping me through a serious plateau. I’ve been working out for about 10 years and had lost around 60lbs. I’ve since gained back some of the weight despite continuing different workout programs. Built with Science brought me back to basics , reinforcing knowledge about nutrition and body mechanics. I’d recommend this program to anyone from newbies to busy parents to fitness enthusiasts looking to improve their overall health.
-- NatiRX, 2026-08-29

### *---- "Not great"
Clunky app that’s difficult to use. It’s okay at tracking food but the workout side is pretty poor. Way better off getting a different nutrition app and a workout app like Caliber.
-- kyukca18, 2026-08-28

### ***** "The fitness app to rule them all"
I had watched Jeremy’s videos for a while before deciding to try out the app. I felt let his videos were interesting enough that they started getting me interested in fitness. After getting married and putting on a little weight, I thought I’d pull the trigger and give it a try for a month. I started to learn how to count calories, lost a few lbs, and got a workout plan. 9 months later: I’ve lost 25 lbs, I enjoy counting, and I lift more weight than ever. I’m the fittest I’ve ever been and my wife uses the app too. She’s also lost about 15 lbs and we have a whole different outlook on life! Thanks BWS!
-- Levai D, 2026-08-28

### ***** "Moe"
The best working out website
-- Hn2er, 2026-08-27

### ***** "Easy to work with and easy to use"
Workout videos for every movement. An algorithm that focuses on your body specifically, everything is super easy to use and simple. Very easy to log your meals/calories.
-- hobbknocka, 2026-08-27

### *---- "Is it really so hard to take a picture of a meal?"
I think this is a good app for logging workouts and meals, but the AI implementation is really over the top. The worst offense is that on the menu where I log my meals I have to look at AI generated images of food that look so alien they make me want to throw up the meal I’m trying to log.
-- Secret Agent Santa, 2026-08-26
