FormX is a motion analysis app dedicated to perfecting your sports and training form. Its standout feature is the ability to play and compare two videos side-by-side simultaneously.

Whether it's a golf swing, baseball pitching and batting, or a track and field sprint start, this app supports performance improvement in any scenario where body movement, speed, and timing are critical! [Key Features] Dual Video Comparison (Side-by-Side Analysis) Play videos of your "past self" and "current self," or a "pro athlete" and "yourself" side-by-side simultaneously. Visually comparing them reveals subtle differences in form and timing that are hard to grasp through words or feeling alone. Precise Time Measurement & Gap Comparison Accurately measure the time of specific movements in your videos! Using the dual comparison mode, you can check the exact "time gap" between the two videos at a glance. By quantifying delays and speed differences, you can elevate the quality of your practice. Advanced Playback Controls Supports slow-motion and frame-by-frame playback. Review your form in deep detail without missing a single split-second movement. Export Analyzed Videos Save your side-by-side comparisons and time-stamped analysis videos directly to your camera roll! It's incredibly easy to share with your coach, friends, or upload to social media. AI Pose Detection (Body Pose Overlay) Automatically tracks joint and skeleton movements of the person in the video and overlays them on the screen. This is highly effective for checking body axis stability and core balance. Ad-Free Option (One-Time Purchase) Upgrade to completely remove in-app ads. Enjoy a wider, distraction-free screen so you can focus entirely on your analysis. [Highly Recommended For:] Athletes who want to compare their form side-by-side with pros or advanced players. Competitors in sports like track and field, swimming, and racing who want to improve their form and shave off split seconds. Players wanting to analyze pitching mechanics in baseball, or swing speed and timing in golf. Coaches and instructors looking to provide clear, visual feedback to students using side-by-side videos and hard data. Achieve your ideal movement and perfect your timing with FormX!

LapWatch Pro は、iPhone の物理音量ボタンで操作できるストップウォッチアプリです。 音量+でスタート / ストップ、音量−でラップ記録を行えます。画面に触れずにラップを記録しやすく、ランニング、陸上競技、インターバルトレーニングなどの場面で素早い操作が可能です。 従来のストップウォッチアプリでは、画面タップで記録をするものが多かったです。便利である一方、画面をみていないとタップしたつもりが別の場所をタップしているという事例が多発していました。LapWatch Proでは、iPhone の物理音量ボタンによって計測を実施できるため、押し間違いを減らすことができます。 計測したラップタイムは一覧で確認でき、基準ラップとの差分や直前ラップとの差分も表示できます。保存したセッション履歴は後から見返すことができ、名前の変更、削除、CSVエクスポートにも対応しています。 主な機能 ・音量+でスタート / ストップ ・音量−でラップ記録 ・ラップタイム、スプリットタイムの表示 ・セッション履歴の保存 ・履歴の閲覧、名前変更、削除 ・CSVエクスポート ・日本語 / 英語の表示切り替え ご注意 ・音量ボタンによる操作は iPhone 実機での利用を前提としています ・広告を表示する場合があります 利用規約: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
