About

HARDN is a near-beta fitness platform built around one idea: stop tracking data without knowing what to do with it next.Most fitness apps tell users what they lifted or ate. HARDN combines workout tracking, nutrition, progress analytics and an AI-powered coach to help users understand their progress and decide what to do next.What’s already built:Full workout tracking with routines, sets, reps, weights, rest timers, history and PRsNutrition tracking for calories, protein, carbs, fat, foods and mealsPersonalized AI Coach grounded in the user's actual training dataDeterministic progression / “Next Move” systemHevy CSV importer that preserves existing workout historyExercise library with 1,500+ exercises supported by an external catalog integrationTraining analytics, e1RM tracking and a multi-tier ranking systemUser profiles, social feed, likes/comments and privacy controlsPrebuilt workout splits and custom routinesFlutter mobile app with Supabase backend and cloud syncAdmin/control infrastructure2,000+ automated testsHARDN has undergone a major mobile UI redesign and is currently being prepared for closed-beta testing.
