「災害用パーソナル・アラート(PAD)」は、災害時に個人の属性に合わせた避難行動を支援するシステムです。本アプリでは、避難所もしくは避難場所をマップ上に表示し、カメラ機能や位置情報を用いることで、避難行動や避難生活を支援し、問題なく避難できているかを確認します。そのため、バックグラウンド方式で利用者の位置情報を取得し、継続して収集します。 防災とは、災害対策基本法第二条第二号において「災害を未然に防止し、災害が発生した場合における被害の拡大を防ぎ、及び災害の復旧を図ることをいう」と定義されています。 本アプリは、防災情報をプッシュ通知でお知らせします。災害発生時は、現在地周辺の避難所もしくは避難場所までのルートを表示することで、避難行動を支援します。避難所もしくは避難場所への到着時に、カメラ・位置情報・テキストメッセージなどを用いて避難完了を報告してもらうことで、利用者の避難状況を把握します。
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 2 screenshots above are 災害用パーソナル・アラート【PAD】's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: 災害用パーソナル・アラート【PAD】 runs a light set with one background colour (#FCFCFC) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #1C2C8C, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
