Delts

什么是 Delts？

Delts is an iPhone gym tracker with one rule: the red button runs your workout. Start it, log sets, reps and RPE while you train, stop — your session is timed, saved to history, and your calorie burn is estimated automatically. The AI Coach is different: it sees your real workouts, body progress, and goals, and can analyze photos of equipment, meals, or form. Everything local is free forever; AI is Premium. Open source, built solo by an ACE Certified Personal Trainer.
