Seeing the same food recommendations and doing the same routine for this long is demotivating. Third, considerations for human size and age need to be taken into account. I’m small and middle aged and female so my weight loss is slower than the app’s algorithm algorithms have predicted. The app keeps decreasing my calories because my weight loss is not keeping up with predictions. Now, I understand 1000 calories a day is not good for me, but others may not leading to potential concerning health issues. Good reminder that these apps algorithms are normed for average populations, which is fine but others should use with caution. ### 4/5 — Workout feedback *2026-08-21, version 3.20.0* No description about breaks in supersets ### 5/5 — Great app and content *2026-08-19, version 3.20.0* Happy to support this app and content creator after years of top quality YouTube content. Thanks! ### 5/5 — Love this app *2026-08-19, version 3.20.0* Absolutely fantastic! Bought a subscription for my niece as well ### 4/5 — Great app but one caveat *2026-08-18, version 3.20.0* I think the app is amazing. The food tracker is probably the best I’ve ever used. Also, the workouts and the instructions to the workouts are also very well done. I’ve never experienced a glitch. But the one caveat that I have with this app is the workouts are not intuitive. Meaning I was doing the same workouts for eight or nine weeks and I wondered “when is it gonna change?” And… I guess the answer is… they don’t. You yourself have to manually change it for a similar exercise. If somehow they can gear it (the AI?) where you’ve either reached the pinnacle for yourself or maybe it’s time to switch and it does it for you would be ideal. ### 5/5 — Best in Class!!! *2026-08-18, version 3.20.0* This has been instrumental in me losing 20 pounds. The food tracking is magnificent and it gives you recommendations for changes in calorie intake. The workouts are brilliant and if you don’t believe me, you should check out Jeremy on YouTube.. Also, once you get kind of bored of a workout, you can ask the AI to give you a new one based on the equipment that you have at home or in your gym. I went from a four day a week workout to a shorter six day a week workout easy Peezy if there’s an exercise that you don’t have or you just don’t like you can swap exercises with an exercise that has similar muscle groups. ### 5/5 — Great app *2026-08-18, version 3.20.0* Great app! For a long time I tried to get in shape and failed. I was so fed up that I almost gave up. Then this year I came across your YouTube video and I decided to tried. I like the 30-days trial and the fact that the app keeps me accountable. I also like the lessons to help me understand how to properly diet and workout. One thing I will recommend, actually it’s more than one; first I sometimes go for a bike ride with my kids. It would be awesome to capture it as a cardio in the app. I looked for bike or bicycle and couldn’t find it. My friend also invited me for a spinning class. I was also trying to enter that in the app and was not able to do so. Second, is it possible to have a preview of the workout before it swap? Every time I am trying to swap an exercise, I have to select the exercise and now look to make sure it matches what equipment is available. It would be great to preview before swapping. ### 5/5 — Great App *2026-08-17, version 3.20.0* Great app, easy to navigate and learn. Nutrition and training advice all in one! I highly recommend it! ### 5/5 — Great App! Easy to use *2026-08-17, version 3.20.0* Not only is this app easy to use, but it has everything you need to get started. I am doing this with my 16 year old son and we are both seeing results. ### 5/5 — Yes! Finally a fitness app that… *2026-08-17, version 3.20.0* Finally, an app that is functional and what the majority of us need weightlifting. ### 3/5 — Solid app *2026-08-16* Love the nutrition and fitness all in one app. Love the daily check ins. Don’t love the exercise programs the app offers. If you pick a target muscle group the program doesn’t target that muscle group. No auto update of exercises after a certain period of time to keep processing. The AI workout generator doesn’t work. If they fix these issues it’s a 5 star app and I will continue using them for many years! **Developer response:** Hello!

Best, The Built With Science Team ### 5/5 — Slowly but Surely *2026-08-16, version 3.20.0* This app is slowly but surely changing my life. I have always followed Jeremy’s videos on YouTube and this is just an extension of his vision helping people like me who struggle with consistency. Still long ways to go but I am getting better. ### 5/5 — Great app *2026-08-15, version 3.20.0* I honestly love this app and will subscribe for the whole year. ### 5/5 — Takes the guesswork out of getting fit *2026-08-14, version 3.20.0* Workouts, calories, macros, recipes and trainer advice.. this app takes the guesswork out of getting fit. Every aspect is thought of and provided for you. Make a decision to get better and download this app. ### 5/5 — Pretty Awesome App. *2026-08-14* Great app so far. It’s got a wide selection of foods in the database to record your nutrition (has a lot of UK foods too). Especially like the breakdowns of how to perform each exercise which is handy when in the gym. The lessons are a good touch too, builds upon your knowledge to assist with the lifting. Would be great if you could import cardio activities from other apps, like Apple Health or Garmin to give that more detailed picture of what calories / activities you’re doing. Update 14 Aug 26. 100 days in and this app is still motivating me to continue with my weight loss goals. As the app tells me, the weight loss isn’t gonna happen overnight but that consistency is key. 5kg lost so far and I’m still invested to lose more. Many thanks to the BWS Team for a great app. **Developer response:** Hello!

Best, The Built With Science Team ## Most critical reviews (10 lowest-rated) ### 1/5 — Not great *2026-08-28, version 3.21.3* 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. ### 1/5 — Is it really so hard to take a picture of a meal? *2026-08-26, version 3.20.0* 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. ### 1/5 — Charging $189 *2026-08-17, version 3.20.0* I didn’t even get far into the app before I saw that it charged 189 on my account, my phone has my card information and I never once clicked the go ahead for it to charge me, I see I’m not the only one this happened to this problem should be fixed immediately because if it weren’t for my bank that money would’ve been most likely gone. This is beyond disappointing. ### 1/5 — Rubbish *2026-08-15, version 3.20.0* Don’t waste your time. App barely works super not UI friendly. Logging meals doesn’t even work. Laggy and glitchy most likely is AI slop. Do yourself a favour and just get a ChatGPT or Claude membership and plan work outs there ### 1/5 — Not worth the money. *2026-08-08, version 3.20.0* This app is very frustrating. It’s not ready for launch and should be free until they can make it work better. The workouts are generic AI slop that will not give you deload weeks. The help bot is not actually able to make any changes. The food logging is extremely counterintuitive. You can’t even copy a lunch and paste it in dinner if you eat the same thing again. I wish I could get my money back. ### 1/5 — Beware of this Scam *2026-07-28, version 3.19.1* The website froze as soon as it got my credit card information. They billed me $189 when I couldn’t even make an account. There was no way for me to cancel the subscription. ### 1/5 — Keep charging after cancellation *2026-07-16* My partner cancelled his account and then they keep charging for it. We’ve emailed support several times and even though on the website they say they will respond within 24 hours, it’s been one month since the first email. They don’t send a cancellation confirmation or anything. We’ve tried logging into his account but it says there’s no account with his email. But when we try and sign up again it says welcome back, login in with your password. **Developer response:** Hello! We're very sorry to hear about this experience, and we understand how frustrating it must be. This definitely isn't the level of support we aim to provide. We'd like to look into what's happened with the account and the billing. Please ask your partner to contact us again through our support email address. If you do not hear back from us within 24 hours, please contact us on Facebook. We'll investigate this as quickly as possible and work to get everything sorted out! ### 1/5 — Needs Swimming *2026-07-16, version 3.19.0* The app needs to add swimming as an activity as well as more machines including assisted pull-up’s and dips. ### 1/5 — Forced into subscription in second step. *2026-07-07* Tired of apps hiding subscriptions behind sign up steps. I get that you’re trying to skip out on paying Apple/Google their cut, but just be honest that your app will cost hundreds of dollars off the jump. **Developer response:** Hello! Thanks for your honest feedback. We understand how frustrating it can be when pricing isn't as clear as you'd expect. We aim to be transparent about our subscription options before any purchase is made, and we appreciate your comments. We'll share your feedback with our team as we continue improving the experience for future users. Thank you! ### 1/5 — Not billed via Apple *2026-07-06, version 3.18.4* Didn’t get past payment. Takes you to a separate site for billing… why not bill thru Apple? Payment via the App Store provides easy management, cancellation, etc. For that monthly/annual cost, you can give $AAPL a cut ## Most praised reviews (10 highest-rated) ### 5/5 — Built with Science *2026-08-29, version 3.21.3* 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. ### 5/5 — The fitness app to rule them all *2026-08-28, version 3.21.3* 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! ### 5/5 — Moe *2026-08-27, version 3.21.3* The best working out website ### 5/5 — Easy to work with and easy to use *2026-08-27, version 3.21.3* 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. ### 5/5 — Motivating *2026-08-27* The full body workouts are a game changer. It’s a nice app, combines several free apps in one. You can do it the free way, but this app is motivating and convenient to have everything in one place. The AI is useful as well. Been using it for about 2-3 months, I’m happy with it. **Developer response:** Hello! We’re so glad you’re enjoying the full-body workouts and the convenience of having everything in one place! It’s great to hear the app and AI features are helping keep you motivated and on track. Thanks for sharing your experience! Please contact us at support@builtwithscience.com if we can assist you! ### 5/5 — This app is great! *2026-08-26, version 3.20.0* The app makes a totally unique workout schedule and even has nutrition coaching! They really thought of every thing! The only thing I wish they would add was a check in on your injury’s before your workouts so if your knee was hurting it could show you replacement options for just that workout. It does have an option to do this when you sign up, but not throughout your training sessions and since my specific injury is kind of different every day that doesn’t really help me. Other than that it’s a great app! ### 5/5 — Removes the guesswork *2026-08-24* Note: I am a beginner (~1 year of lifting), so my review may differ from yours. I previously tried building my own program with YouTube videos and used macro factor for nutrition tracking. I ended up not making the progress I wanted, so I gave this one a try after ~9 months. I really like the hand holding that it provides: I don’t need to guess when I need to increase the reps or weight, the app does it for me. Creating my program was easy thanks to the onboarding quizz. I learned a bunch of info with their built-in lessons. Some were known because i watched a lot of content saying the same thing. But if you’re a complete beginner it might be eye opening on all the basics. The nutrition tracking works great but the database feels less complete than macro factor, even though it’s getting better. Especially in Europe. We can feel it being somewhat US-centric and having a growing international user base. It feels like a great combo of everything to me. The embedded AI helper sometimes fumbles (as all AIs do), but overall it answers the questions I ask and gives good advice for basic stuff. It having access to my data is a plus, when it’s smart enough to actually use it instead of guessing. I have not tried other « all in one » competitor training apps, but I’m happy with this one! **Developer response:** Hello! Thank you for such a thoughtful and detailed review! We’re thrilled the personalized progression, onboarding, lessons, and AI support have been helpful. We also appreciate your feedback about the food database and international coverage, especially in Europe, and will share it with our team. Please contact us at support@builtwithscience.com if we can assist you! ### 5/5 — worth it *2026-08-21, version 3.20.0* very thoughtfully designed app. makes tracking workouts and food easy and tells you exactly what to do, but with the flexibility to change things up too. I’m glad I tried it. one suggestion for the developers: I would love if it were possible to get just the workout tracking part of the app as a discount. I am not really trying to change my weight, but the workout tracking is so thoughtfully designed i want to keep using it, but the price is a little steep for just that. its been a great way to organize my workouts and incorporate my PT into my gym sessions (I have a lot of custom exercises). It’s been the only way I consistently do my PT ### 5/5 — Exceptional *2026-08-20, version 3.20.0* By far the best fitness app I’ve tried out of a handful. ### 5/5 — Great all-in-on platform *2026-08-19* I love that the app is easy to use and it has everything you need all in one app. And I also love that for the workouts you can substitute exercises when accommodating for injury or lack of equipment. It’s great!! **Developer response:** Hello! We’re so glad you’re enjoying the app’s simplicity and all-in-one approach! It’s great to hear that exercise substitutions are helping you adapt your workouts to your needs and available equipment. Thank you for the wonderful feedback!
