Delts

About

Delts is a gym tracking app for iPhone that operates on a single principle: the red button controls your workout. Press start, then record sets, reps, and RPE as you exercise. When you stop, your session is automatically timed, saved to your history, and your calorie expenditure is calculated. Its AI Coach stands apart by reviewing your actual workouts, physical progress, and objectives; it can also assess photos of equipment, meals, or your lifting form. All local features are free permanently, while the AI functions require a Premium subscription. The app is open source and independently developed by an ACE Certified Personal Trainer.
