OpenMapは、「今、営業しているお店」を探したり、現地の最新状況をみんなで共有できるマップアプリです。 「営業時間では営業中のはずなのに、行ってみたら休業していた」 「臨時休業だった」 「営業時間が変更されていた」 「混雑していて入れなかった」 「現金しか使えなかった」 「設備の故障などで、一部のサービスが利用できなかった」 そんな、通常の地図情報だけでは分かりにくい“今の状況”を、実際にその場所を訪れた人が投稿できます。 営業中のお店や24時間営業のお店を探すだけでなく、誰かの投稿が次に訪れる人の助けになる。 「困った人が、次の人を助ける。」 OpenMapの「24」には、24時間営業のお店を探せること、そして24時間いつでも、あなたの「困った」をサポートするという意味を込めています。 OpenMapは、地域のリアルタイムな情報をみんなでつないでいくマップアプリです。 【月額サブスクリプションについて】 本アプリのダウンロードは無料です。OpenMapの各機能を利用するには、アプリ内で提供される月額自動更新サブスクリプションの購入が必要です。料金は購入前の確認画面に表示され、Apple IDに請求されます。 「利用規約(Apple標準EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/」
