MassMetrics is the all-in-one fitness tracker built for serious lifters and bodybuilders who care about the details. Instead of tracking workouts in one app, macros in another, bodyweight somewhere else, and progress in a spreadsheet, MassMetrics brings everything together in one place. TRACK YOUR TRAINING Log workouts, build programs and templates, track sets, reps, weight, and progression, and review advanced performance metrics over time. TRACK YOUR NUTRITION Log food, track calories and macros, and stay on top of the targets that support your current goal. TRACK YOUR BODYWEIGHT Set cutting, bulking, or maintenance goals and follow your weight trend over time instead of reacting to individual weigh-ins. TRACK YOUR DAILY ACTIVITY Monitor steps alongside your training, nutrition, and bodyweight so you can see the full picture in one place. SEE HOW EVERYTHING CONNECTS MassMetrics gives you a centralized dashboard for the metrics that matter most—training performance, calorie intake, macros, bodyweight, steps, and progress. GO DEEPER THAN THE BASICS Review workout history, estimated 1RM progression, bodyweight trends, and individual metrics to better understand how your training and nutrition are progressing. BUILT FOR PEOPLE WHO TRACK EVERYTHING MassMetrics is designed for lifters who want more than a basic workout log or calorie counter. If you're serious about training and already keep a close eye on your numbers, MassMetrics gives you one place to manage them all. Train. Track. Progress.
