## What is Pocket Motion Fitness?

Precision counting, expanded

• Standing march, high knees, step-up, and lunge (forward / reverse / side) —
six exercises now share the V11 hip-flexion algorithm that already powers our
reliable squat counter. Walking, twisting, and phone-adjustment motions are
reliably rejected.

• "Why isn't it counting?" is gone. The voice coach calls out exactly which
leg to lead for a right-side-pocket sensor:
  — Step-up: "Step up leading with your right knee"
  — Lunge: "Step your right foot forward"
  — Reverse lunge: "Step your LEFT foot back — right leg supports"
  — Side lunge: "Step your right foot to the side"

• Sit-up and push-up cannot be reliably rep-counted from a side-pocket sensor
— we'd rather give you an honest timer than fake reps. Both switched to timed
mode.

• Fixed a rare iOS launch crash (NSInternalInconsistencyException) on certain
scene-restoration flows.

Pocket Motion Fitness counts your reps and guides your workout while your
phone stays in your pocket. No camera. No smartwatch. No tripod. Just your
phone.

■ Why it's different
Pocket Motion tracks the gravity vector rotation in your phone to measure the
actual hip-flexion angle of your thigh. Not blind impact detection — proven
biomechanics. One V11 algorithm now counts six exercises with consistent
precision.

■ Precision-counted exercises
Squat / Chair squat / Standing march / High knees / Step-up / Lunge (forward /
  reverse / side)

■ Timer-mode exercises
Plank / Side plank / Wall sit / Dead hang / Squat hold / Glute bridge hold /
Sit-up / Push-up

■ Honesty is accuracy
Sit-up and push-up cannot be reliably rep-counted from a side-pocket sensor
(sit-up: thigh stays flat; push-up: plank discipline holds thigh angle within
2-5°). Instead of faking counts, we run them as timed activities. Honesty over
  false confidence.

■ How to use
1. Slip your phone into your right side pocket
2. Start the exercise (double-tap covenant)
3. Follow the voice guidance for proper form
4. Counts stop automatically when you're done

■ Real-time voice coach (Korean / English)
Which leg to lead, how many reps you've hit, how your form looks — every cue
spoken so you never have to glance at the screen.

■ Haptic feedback
Vibration confirms every counted rep so you stay focused on movement, not on
UI.

■ Privacy first
All sensor data is processed on-device. Motion data never leaves your phone.

■ No camera, no tripod
No filming, no propping the phone up. Just move.

Supported languages: Korean / English
