Really loved this app at first, it definitely helped me as a beginner to build routines and find exercises I like and can push myself on. Knocking it down a bit because the strength score seems very arbitrary and can be incredibly demotivating. I had PRs on 6 different leg exercises this past week and my strength score for legs went down 60 points. I really love the community aspect but I think I will move to a tracker that just tracks reps and doesn't make me feel bad :(

Great that you really like aspects of the app, aside from Strength Score. If you don't find Strength Score to be helpful, you can actually turn this off by going to Menu > General. Separately, if you'd like clarification on any of the score changes you've seen, please reach out to support@caliberstrong.com and we'll be happy to help from there.

The fact that it has a social area and has no block option, a basic feature that's pretty standard now, makes it so you can't block out annoying pests. Strength score is okay, but a bit ambiguous and isn't conducive to hypertrophy. So, if your goal is hypertrophy, the strength score can be misleading. Also, what in the world works out shoulders!? I do incline bench, front lat raises, and other shoulder movements, and the shoulder score doesn't change for them at all.

The shoulder portion of the score should factor in most of the common shoulder exercises. If you're not seeing updates to this sub-score, please reach out to support@caliberstrong.com and we'll be happy to help. Regarding a block feature, this is something that we are planning on adding in an upcoming revamp to the Social section as well.

This is by far the best fitness app on the market. You can easily track your workout routines. I do strength training and the user interface for tracking reps, sets, and weight is so easy to use. It gives you a score to help you stay motivated and invested in accomplishing training goals. There are videos and explanations for each exercise so you can be assured your form and technique is correct. Caliber also gives you access to renowned trainers who will help you create a training regimen.
