There's a lot to like about this app, but it's not finished. A lot of the lessons are cut off so they end mid sentance. Half the videos are AI narration which I dispise. I much prefer Jeremy's narration. The food choices are much weeker than other apps that I used. Need a better repository for non-US users. It has me in the same two exercises for 72 days (my current streak). Yes I can make my own but that's the point of the app... Variety and help more. I have lost 10lbs and I'm looking better

I love this app! It is by far one of the best fitness apps that I have ever used! The workout tracking is simple with helpful form videos that are easy to reference between sets, the meal logging (which is usually a pain in other apps) is intuitive, and the mini lessons and Jeremy AI are just fantastic! I highly recommend checking it out! Kudos to Jeremy and the team!

it's good for nutrition tracking and weight tracking, but the workouts that it gives you are pretty bad. for example, on a push day it would have barbell bench press as the third exercise, which should never happen. Also, the excersise variety is very minimal. For example, there are no skull-crushers, weighted leg raises, wide grip rows, etc. For an app that claims its workouts are 'science based', it's doing a pretty bad job.
