Sedentary office pros (subhealth): you know Kegel can boost health, but meeting、coding... kill consist. normal apps: too visible. Native macOS fix: Tiny status bar icon+subtle trackpad haptics guide “contract-hold-relax-rest” discreetly (no side-eye). Visual/haptic guidance: exercise while working, zero mental load on timing/control. Fragmented gaps: frictionless sessions (work & health, no trade-off). Preset modes:Begin/Standard/Advance/Quick/Endurance + custom rhythm, until ideal intensity.
