Look no further than Metrobrome! Metrobrome uses your phone’s camera and artificial intelligence to watch your lifts. The app helps you lift with more time under tension, which is the biggest driver of muscle growth. It also checks your range of motion to ensure that you are targeting the correct muscles. If you’re looking to get stronger, leaner, and hotter, then Metrobrome is for you. Scientific studies around the world have shown that progressive overload is the key to muscle growth.

Our advanced artificial intelligence ensures that you quit wasting time through ego lifting. Our unique scoring system allows you to improve your strength using the number of reps, weight, AND tempo of your lifts to maximize your gains. Simplify your fitness journey using Metrobrome's revolutionary scoring system. This innovative scoring system provides valuable feedback on your progress, allowing you to identify areas where you're excelling and areas where you need to improve. And with our progress tracker, you can easily set and achieve your fitness goals, no matter how ambitious they may be. Reduce your risk for injury by achieving the same results with lighter weight. One of the most common reasons people quit before they've achieved their goals is getting hurt by ego lifting. Metrobrome fixes this by providing immediate feedback on your lifting tempo and range of motion. Metrobrome provides visual and audio cues to ensure that you are using the appropriate amount of weight to make sure you don't get hurt. Whether you are an experienced lifter or just starting out, Metrobrome can help you achieve your goals quickly and easily. Download today!
