HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (209 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ However, it's not suitable for long-term use due to its limited exercise library.
★★★★★ The website froze as soon as it got my credit card information.

★★★★★ You can create your own exercises, but a huge appeal of the app are its videos, so when you have to keep adding exercises that the app doesn't have, you lose the purpose of having this app.

WHAT THEY ASK FOR
  • Keep up the great work and I wish Built With Science all the success. 5★, Oct 22, 2026
  • One thing I wish was on there is to be able to see how the calories burned through workouts affects your total calorie allotment. 5★, Oct 5, 2026
  • I wish I could tell it “hey my Achilles is hurt or select a body part that is injured” and it automatically swaps out the items in the workout program that would be easy to do while going through Achilles rehab. 4★, Sep 21, 2026
  • Terrible for newbies but not bad for people who already know how to workout and just need accountability for nutrition. 4★, Sep 21, 2026
  • I do wish it would be more affordable so that more people can utilize this great and essential tool in their daily lives 5★, Sep 10, 2026
  • It would be nice just to have a section to view each individual exercise. 4★, Sep 9, 2026
  • 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. 5★, Sep 5, 2026
  • 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. 5★, Aug 26, 2026

★★★★★ Down 30lbs, two pants sizes, two shirt sizes, and in the best shape of my life at 42. When I started I couldn't do a pulll up and now I can do almost all 20 of my scheduled reps in a workout!
★★★★★ Really appreciate BWS. I've been on active duty for 23 years. I've been in multiple services, also have been a firefighter ENT. I've always struggled with finding something that fits the aspects of Daily life as a…
★★★★★ It's easy to swap out and pick an alternative workout for the same muscle.

★★★★★ The app really helps keep things organized in one place.
★★★★★ The AI food scanner is especially helpful and takes all the work out of logging your meals.

Accurate, great results7%

28 of the 4 and 5 star reviews.

★★★★★ Both the food logging and exercise guidance halves of this app are exemplary. Not only that, but there are regular updates with new features. Worth every penny! I am so glad I got this. (been using it for 90 days.)
★★★★★ Awesome job because the app doesn't just have you lose “weight” without addressing losing fat- I would give five stars but they don't use lean mass numbers- you can't really validly calculate “calories” if you don't…
★★★★★ The app works great as a nutritional tracker and diet plan but as far as workout goes it's greatly lacking as there are plenty of workouts that just aren't able to be tracked or shown examples of.
Fun, addictive7%

27 of the 4 and 5 star reviews.

★★★★★ I've used it for almost 2 weeks and enjoy the program and the lessons.
★★★★★ Really enjoying this and brought my wife to the fold as well looking forward to my results.
★★★★★ I enjoy how much detail went into this app.

The app really helps keep things organized in one place. I appreciate the videos for the exercises showing form, and I love the built-in timer for rest; it keeps the workout flowing nicely and feels efficient

★★★★★Oct 23, 2026
Amazing App!! Can’t wait for the iPhone Duo update

Jeremy and his team have worked hard on this app. Love every second of it, besides the outrageous price tag. Bring it down to $10, and my whole family would be using it. Also, can’t wait for the iPhone Duo update. This app is perfect for the full screen experience.
