通販の服、サイズ選びで迷っていませんか? 同じ「M」でも、ブランドや商品が変われば寸法はさまざま。FitCheck AIは、あなたが実際に持っている服を基準に、気になる商品の実寸を比較できるサイズ選びサポートアプリです。 【手持ちの服が、あなた専用の基準に】 「ちょうどいい」「少しゆったり」など、着心地がわかっている服を登録。その服と商品サイズを比べるので、数字だけのサイズ表が具体的な差として見えてきます。 【使い方は3ステップ】 1. よく着る服の身幅・着丈・肩幅などを登録 2. 通販の商品サイズ表を撮影、または数値を入力 3. サイズごとの差を見やすい比較結果で確認 【買う前の判断がもっとスムーズに】 ・複数サイズの違いをまとめて比較 ・トップス、ボトムス、ワンピースなどに対応 ・候補商品の写真やブランド名も一緒に保存 ・比較履歴から、迷っている商品をあとで見返せる ・AIで読み取った寸法は確認して自由に修正可能 【こんな方におすすめ】 ・通販でMとLのどちらにするか迷う ・ブランドごとのサイズ差がわかりにくい ・手持ち服に近いシルエットの商品を探したい ・購入前の採寸や比較を毎回やり直したくない 身長や体重の入力は不要。あなた自身の「よく合う一着」から、すぐに始められます。 FitCheck AIで、サイズ表を眺めて迷う時間を、納得して選ぶ時間へ。 ※AIによる読み取り結果は必ずご確認ください。本アプリは寸法差をもとにサイズ選びを支援するもので、実際の着用感を保証するものではありません。 Not sure whether to order M or L? A familiar label can fit very differently from one brand—or even one product—to the next. FitCheck AI turns a piece you already love into your personal sizing reference, so an online size chart becomes a comparison you can actually use. YOUR CLOTHES, YOUR REFERENCE Save the measurements of an item whose fit you know. Compare a new product against it to see exactly how much longer, wider, or shorter each size is. THREE SIMPLE STEPS 1. Add the measurements of a favorite item 2. Scan a product size chart or enter the numbers 3. Review clear differences for every available size MAKE A MORE INFORMED CHOICE • Compare chest, length, shoulders, sleeves, waist, inseam, and more • Use tops, bottoms, dresses, and other categories • Keep product photos, brands, and names with each result • Save comparisons and revisit your shortlist later • Review and edit every AI-read measurement No height or weight is required. Start with the best reference you already own: the clothing that fits the way you like. Spend less time decoding size charts and more time choosing with confidence. AI-read measurements should always be reviewed. FitCheck AI compares garment measurements to support your decision; it does not guarantee how an item will fit. プライバシーポリシー: https://my-app-fitvheck.web.app/privacy-policy.html 利用規約(EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ FitCheck AI Premium (auto-renewable subscription) - Yearly / Monthly plan - Payment is charged to your Apple ID account at confirmation of purchase - Subscription automatically renews unless canceled at least 24 hours before the end of the current period - Manage or cancel in Settings > Apple ID > Subscriptions Privacy Policy: https://my-app-fitvheck.web.app/privacy-policy.html Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
