The fastest gym logger — with a coach built in.
Native iOS. Two-tap set logging. A rest timer that never interrupts you. And an AI Coach that adapts your program based on how the last sessions actually went.
Everything you need. Nothing you don't.
A big “Next” button advances weight and reps for you, so a full working set takes a second — no scrolling, no menus.
A persistent rest bubble follows you across the app and iOS as a Live Activity. Cancel or add 30s from anywhere.
Generate programs from goals and equipment. Progressive overload and recovery-aware auto-regulation adjust the plan session to session.
Flag a joint or muscle to avoid and Du Fitness proposes substitutions with matching stimulus.
Volume by muscle group, estimated 1RM, PR history, weekly streaks, and a muscle heatmap — no paywalled charts.
Log sets, control rest, and see next-up from the Watch. Home-screen widgets show today's session and streak.
Workouts are written to Apple Health with duration, calories, and heart rate so the ring closes automatically.
Sync between iPhone and iPad, and export your entire history as CSV whenever you want.
One subscription unlocks both.
Du Pro also unlocks Du Nutrition — food and macro tracking that syncs with your training through Apple Health.
