CoSync: Group Workout Log Live

Rally your squad. Beat your ghost. Sync your strength. Stop lifting in a vacuum. CoSync is the high-velocity fitness tracker and workout log designed for those who believe training is a team sport. Whether you’re chasing a new 1RM (One Rep Max) or hitting a progressive overload goal with your crew, CoSync turns every gym session into a "Boss Raid." ⚡ BEAT YOUR GHOST (SOLO MODE) Don't just track your weightlifting sets—surpass them. Our "Solo Mode" is built on the Beat Your Ghost philosophy to help you stay consistent and see results. The Ghost Gap: See exactly how much weight or how many reps you need this set to beat your past self. Muscle Radar: Visualize your training volume across 7 key categories to ensure no muscle group is left behind. Workout Density: Track your volume-per-minute efficiency with auto-timestamps. Progressive Overload Tracking: Use global date-slicing to compare your current strength training to your winter bulk or last year's performance. 🛡️ JOIN THE GUILD (SOCIAL GYM TRACKING) Create or join a Gym Guild and turn your workout partners into a synchronized powerhouse. Boss Raids: Work together to defeat the Boss. Every pound the group lifts chips away at the Boss's massive HP. Can your squad kill the boss before the timer ends? The Overlap Metric: No more cluttered leaderboards. CoSync automatically finds the strength exercises your group has in common and ranks you only on the lifts you actually share. Pure Performance: Compete on absolute weight or estimated 1-Rep Max (1RM) without the clutter of bodyweight metrics. 🛠️ BUILT FOR THE WEIGHT ROOM We know you're at the gym to lift, not to stare at your phone. CoSync is the simple gym tracker that stays out of your way. Plate Calculator: A lightning-fast weight plate logic tool that tells you exactly what to put on the barbell so you can get back to work. Seamless Sync: Powered by a high-performance backend, your workout logs and Personal Records (PRs) sync to your group’s feed the second you hit "Finish." CoSync is more than just a gym diary; it’s a competitive platform for bodybuilding, powerlifting, and functional fitness. Download CoSync today and sync your strength.
