Huberbro is an AI hypertrophy coach that is completely built through SMS. Just text in your workouts and you'll get coach-like feedback to help guide and improve your training.
Biased review - I'm the solo dev on the project. That being said, beta users (advanced lifters) have provided overwhelmingly positive feedback. This is the number 1 tool for seasoned gym goers to get another set of eyes on their training with very little added input friction.
