Keep the phone out of the set
Use the watch for between-set actions when your hands, pockets, or focus make the phone annoying.

Apple Watch App
Each feature is built around a real training outcome, so you can make your next lifting decision with more confidence.
Use the watch for between-set actions when your hands, pockets, or focus make the phone annoying.
Haptic alerts and glanceable timers help you return to the bar without losing track of the clock.
Watch sessions can write proper workout data so strength training counts where it should.
How It Works
SuperFlex keeps the main path fast while preserving the context serious lifters need.
Begin the workout from either device and keep the same session model in sync.
Confirm reps, adjust weight, and mark sets complete without unlocking your phone.
Let the watch tell you when the interval is over while you stay focused on recovery.
Use the phone when you want the bigger screen for history, analytics, or cleanup.
Why It Matters
A phone is great for review, but awkward between sets. Apple Watch gives SuperFlex a lower-friction surface for the moments when logging needs to happen quickly and quietly.
