### 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, version 3.20.0*

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!

### 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.

### 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

### 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, version 3.20.0*

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.

### 2/5 — App Issue

*2026-08-13, version 3.20.0*

First time downloading it, tried to login in lunch food and after trying to “Log Items” multiple times, I gave up. 
Uninstalled and installed and same issue was happening. 
Unable to log in my first lunch food

### 3/5 — So far, 3 stars. Many things could be added.

*2026-08-13, version 3.20.0*

The first thing I noticed after the first workout was that there is no post stretch. I’ve had a few injuries after new workouts in the past because of bad advice. A stretch set based on each workout day would be wonderful.

Second, the integration with the Apple Watch seemed great at first, but during the rest times, it goes from the next set screen (weight and reps) and back to the timer of the last seconds a few times and vibrates at random times. Looks buggy.

Another major thing for Apple Watch integration is that I cannot use the main fitness app while I’m using BWS. As soon as I start a strength training workout in the main Workout App (made by Apple) the workout ends when I go back to the BWS app.

You guys seem to prioritize your app and we can’t close our rings through fitness or check other specs of our workout. And when the workout is done, it doesn’t even transfer to the main Fitness app. That’s disappointing.

If it wasn’t for Jeremy’s previous videos, I would have not tried the application too. All the AI Slop ads you’ve pushed these past few weeks were NOT needed to bring awareness to your app. You guys can do way better than that. AI as an LLM can definitely help us and also make fitness better, but as a commercial art tool, it really threw me off many times before I decided to give it a go. And that was AFTER I got convinced to try it out after seeing real people trying Jeremy’s challenges on YouTube. Don’t ruin your professional reputation with that.

Other than that, I’m having fun with my new workouts and the nutrition tracking is great. You guys are close to make this a 5 star app for everyone.

### 5/5 — Do better, Try harder!

*2026-08-13, version 3.20.0*

I have watched Jeremy on YouTube for a long time. Finally got a phone that would let me have the Built with Science App. I’ve lost 66 pounds in 3 years. This app will help me lose the next 50. ❤️
