Workout tracker with a layout for every pose, the routine and the exercise side by side
Does SmartGym work on iPhone Duo?
Yes. Apple named SmartGym among the apps optimized for iPhone Duo: routines and exercise details sit side by side, and its release notes describe a layout for every pose.
- Launch partnerNamed by Apple in its Newsroom article of October 22, 2026, on apps optimized for iPhone Duo. The App Store release notes for version 8.1 (released October 16, 2026) say: "SmartGym is ready for iPhone Duo, with an interface that adapts as you fold, unfold and move through your workout. EVERY POSE Enjoy layouts designed for every pose: Closed, Book Style, Fully Opened, Seated and Tent."
Adapted for the fold
- Book · Partly folded
Routine and exercise, side by side
Held like a book, your routine is on one page and the selected exercise on the other.
- Open · Inner display
Live stats, open flat
Fully open, live workout stats and controls fill the display with the Smart Action Button in reach, and your calendar, goals and workouts sit side by side.
- Book · Partly folded
A live dashboard, seated
Set down seated for a HIIT workout, the exercise stays upright and the bottom half becomes a live dashboard with your heart rate chart, calories, zones and controls.
- Standing · Hands-free
Hands-free as a tent
Stood as a tent, the workout stays propped up and easy to follow, with no stand needed.
About SmartGym
SmartGym builds personalized training plans for the gym or home, with an Apple Watch app, workouts created from a plain description, and a library of more than 730 exercises.
Apple named it in its October 22 roundup of apps from Latin America: it “makes it easier to keep up with the next workout, displaying routines and exercise details side by side onscreen.” Version 8.1 says it has layouts for every pose, closed, book style, fully opened, seated and tent: the routine on one page and the exercise on the other, live stats open flat, and a heart rate dashboard on the lower half when it sits on the floor for HIIT.
