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/

Verdict
The clearest difference is ads: LapWatch Pro at none against Swimming Timer's shown. LapWatch Pro also leads on update cadence (daily vs every 3 months). Swimming Timer's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and in-app purchases there is nothing between them.
