3秒遅延カメラは、スポーツやダンスのフォーム確認に特化した練習用カメラアプリです。 カメラを向けるだけで、少し前の自分の動きを画面に表示。撮影してから再生する手間を減らし、動き終わった直後にフォームやタイミングを確認できます。 ゴルフのスイング、バスケットボールのシュート、野球の投球、筋トレ、ダンス、ヨガなど、ひとりで練習する場面に向いています。誰かに撮ってもらわなくても、スマホを置くだけでセルフレビューを始められます。 主な機能 数秒前の映像をリアルタイム表示 遅延秒数をスライダーで調整 背面/前面カメラの切り替え 倍率調整 直前の動きを保存して見返し シンプルで練習を邪魔しにくい操作画面 こんな時に便利です スイング後すぐにフォームを確認したい シュートや投球の姿勢を自分で見直したい ダンスやトレーニングの動きをその場でチェックしたい 毎回動画を撮影して再生する手間を減らしたい 一人練習でも改善ポイントを見つけたい プレミアムでは、広告なし・高画質でより快適にフォーム確認ができます。集中して練習したい人や、細かな動きまで見返したい人におすすめです。 Terms of Use (Standard Apple EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

"LagMe" is a delay camera that keeps showing your movement a few seconds late—so you can check your own form the instant after you move. No recording or playback controls needed. Who it's for - Golf, baseball, basketball, volleyball, dance and more—anyone who wants to check form right away - Solo self-checks, or coaches showing players their movement - Students and players who want "film from behind, review in hand" without expensive gear Key features - Delay playback: your video plays back on a delay you set. Just move, then glance at the screen. - Save the past: tap save to keep the last N seconds—even movements you didn't think to record. - Wireless two-device link: film with one iPhone placed behind the action, review the delayed video on the one in your hand (best for indoor/moderate-size courts). - Shooting tools: grid lines, mirror, front/back camera, pinch zoom. - For saved clips: slow motion, frame-by-frame, still capture, and sharing. Quality - 1080p at 30 or 60fps. 60fps is great for fast motion like a golf swing. - Built to run stably even over long sessions. Pricing - Free to use (with ads). - A one-time purchase removes ads and unlocks longer delay and save-back, up to 180 seconds (120/180s). Buy once, keep it forever. Videos are saved on your device (Photos app) and are not uploaded to any server.
