## What is Video Delay?

See your own movement seconds after you make it.

Video Delay shows the camera feed on a delay. Set the delay, prop up your device, and perform. By the time you look at the screen, your movement is playing back. No recording, no tapping, no scrubbing.

WHY A DELAY BEATS A RECORDING

A normal camera makes you stop, pick up the device, and rewind. With a delay you simply keep practicing. Each repetition plays back on its own while you get ready for the next one, so a whole session runs without anyone touching the screen.

BUILT FOR PRACTICE

- Physical education: vaulting, mat work, high jump, swimming
- Gymnastics and cheer: check landings and body line
- Dance: verify choreography, timing, and formation
- Golf, baseball, tennis: swing path and follow-through
- Martial arts: stance, guard, and kick height
- Music: posture, bowing, and hand position
- Physical therapy and gait training
- Public speaking: gesture and stance

FREE

- Delay from 1 to 20 seconds
- Front and rear camera
- Mirror mode for left/right flip
- Live frame rate readout
- No ads

PRO (IN-APP PURCHASE)

The following features require an additional purchase.

- Delay extended to 120 seconds
  The upper limit depends on free storage. Before you buy, the app shows the longest delay this particular device can hold.
- Two-pane display, split or inset
  Each pane takes either the live feed or any delay you choose, so you can put live next to delayed, or 5 seconds ago next to 30 seconds ago.
- Skeleton overlay
  Overlay: body lines are drawn on top of the video.
  Only: the video is not shown and only the skeleton is drawn, so the background and clothing stay off the screen and you watch the movement itself.
  Split: video on one pane and skeleton on the other, side by side.
- Six colors for the skeleton lines

Pro is a one-time purchase, not a subscription. Once bought, it restores on your other devices signed in to the same Apple Account.

DESIGNED TO KEEP RUNNING

Frames are buffered to disk instead of memory, so a 120-second delay uses no more memory than a one-second delay. Capture runs at 15 fps, and image quality steps down automatically if the device gets warm, so long sessions stay stable. The skeleton is computed on the device; no video leaves it.

NO ACCOUNT, NO ADS, NO DATA COLLECTION

Nothing is uploaded. Nothing is written to your photo library. Buffered frames are discarded as they play back and cleared when you close the app.

PLEASE NOTE

- The skeleton overlay is a visual aid for watching movement. It does not measure or diagnose anything.
- Saving video or still images is not supported.
- iPhone is landscape only. iPad supports every orientation.
- Camera access is required.

Set your device on a tripod or lean it against a wall, choose a delay, and start practicing.

## Key features

- Adjustable delay from 1 to 120 seconds
- Front and rear camera support
- Mirror mode for flipped playback
- Skeleton overlay for body line analysis
- Two-pane display (live vs. delayed)
- No ads or data collection

何故でしょうか？
かなり便利なアプリなので使用したいので調べてください^_^
