About JustGains
JustGains is a comprehensive social workout application designed to consolidate the often fragmented fitness tracking ecosystem. By bringing together lifting logs, nutrition tracking, GPS activity monitoring, and goal setting into a single unified platform, it eliminates the need for users to juggle multiple subscriptions to monitor their overall health. The most impressive technological addition is its AI coaching and voice-logging capability. Athletes can simply speak their sets and weights into the app, completely removing the friction of manual data entry during intense workouts. Furthermore, JustGains addresses a major hurdle in fitness tech—switching costs—by offering a seamless importer that pulls historical data from popular competitors like Strong, Hevy, FitBod, StrengthLog, and Caliber. Finally, the app stands out with its commitment to open data architecture and community building. Users are guaranteed data sovereignty, meaning they can freely export their metrics without being trapped in a walled garden, all while engaging with a built-in social network to share routines and milestones.
