【概要】 UnderLineは、入力している途中の言葉がリアルタイムで相手に届く、新しいかたちの1対1メッセージアプリです。 一般的なメッセージアプリでは、送信ボタンを押してから相手へ言葉が届きます。UnderLineでは、文字を入力した瞬間から会話が始まります。入力した文字を消した場合も相手側の表示へ反映されるため、離れていても、言葉が生まれていく過程や会話のテンポを共有できます。 主な機能 - 入力途中の文章を相手へリアルタイム表示 - シンプルな1対1メッセージ - 公開ID・QRコードによる友だち追加 - れんらく先、トーク一覧、トークルーム内の検索 - メッセージのブックマーク - トークごとの通知オン・オフ、ピン留め、非表示 - 新着メッセージ通知 - ブロック、通報、アプリ内でのアカウント削除 - QRコードを使った暗号化端末移行 - iCloud暗号化バックアップと復元 メッセージ本文と入力途中の文章はエンドツーエンド暗号化されます。プッシュ通知にメッセージ本文は表示されません。 会話のタイミングをつかむことに不安を感じる方や、文字でのコミュニケーションをより自然に楽しみたい方にもお使いいただけます。言葉が完成する前から気持ちが伝わっていく、UnderLineならではの会話をお試しください。 ご利用上の注意 - 入力途中の文章は、同じトーク画面を開いている相手に表示されます。送信前でも相手に見られるため、相手へ見せたくない内容は入力しないでください。 - 通知を許可すると、アプリがバックグラウンドまたは終了中でも新着通知を受け取れます。通知にメッセージ本文は表示されません。 UnderLine is a one-to-one messaging app that lets your conversation partner see your words in real time while you type. Unlike conventional messaging apps, where the other person sees your words only after you tap Send, UnderLine lets the conversation begin from the moment you start typing. When you delete draft text, the change is also reflected on the other person's screen. This makes it possible to share the rhythm of a conversation and the way words take shape, even when you are apart. Key features - Real-time display of text while it is being typed - Simple one-to-one messaging - Add friends using public IDs or QR codes - Search contacts, conversations, and messages within a chat - Bookmark individual messages - Mute notifications, pin conversations, or hide them from your list - Push notifications for new messages - Blocking, reporting, and in-app account deletion - Encrypted device-to-device transfer using a QR code - Encrypted iCloud backup and restoration Message bodies and live-typing text are end-to-end encrypted. Push notifications never include message content. Important notes - Live typing is visible while the other person has the same conversation open. Because text may be seen before you tap Send, do not type anything you do not want the other person to see. - Enable notifications to receive new-message alerts while the app is in the background or closed. Message content is not shown in notifications.
