時間の流れを、ひと目で。 Yokokuは、残り時間や経過時間をカラーバーで見える化する横画面タイマーです。数字を追い続けなくても、時間がどれくらい進んだかをバーの変化で直感的に確認できます。 【こんな場面に】 ・勉強や読書の時間管理 ・仕事や家事への集中 ・トレーニングやストレッチ ・作業と休憩を繰り返すルーティン ・離れた場所から時間を確認したいとき 【主な機能】 ・カウントダウンとカウントアップ ・通常計測と、作業/休憩のリピート計測 ・作業時間、休憩時間、繰り返し回数の設定 ・無制限リピート ・開始、一時停止、再開、リセット ・半分経過、終了、フェーズ切り替えの通知 ・バックグラウンド中のローカル通知 ・画面スリープの設定 ・秒表示のオン/オフ ・左右どちらの持ち方にも合わせられる画面反転 【見やすいビジュアルバー】 画面下部の20本の目盛りが、時間の経過に合わせて左から減っていきます。大きな時間表示とカラーバーが同じ計測状態に連動するため、数字と全体の割合を一緒に確認できます。 【作業と休憩を自動で切り替え】 リピート計測では、設定した作業時間と休憩時間を自動で切り替えます。回数を決めたセッションにも、終了を決めない反復にも対応しています。 【置いたまま使いやすい横画面】 横画面を前提に、大きな時間表示、操作ボタン、ビジュアルバーを1画面に配置。画面の向きはアプリ内で固定できるので、机に置いた端末が傾いても意図せず回転しません。必要なときは画面反転ボタンで切り替えられます。 【必要なときにお知らせ】 通常計測と作業フェーズでは半分経過を、各フェーズや計測の終了時には通知音でお知らせできます。通知音と半分経過通知は設定で切り替えられます。 【画面更新を必要最小限に】 バーは目盛りが切り替わるタイミングで更新し、秒表示をオフにすると数字の更新頻度も抑えます。長時間の計測を考え、不要な継続アニメーションを使わない設計です。 目で時間を捉えて、次の行動へ。Yokokuを、毎日の勉強、仕事、運動の時間管理にお役立てください。 利用規約: https://rinro.jp/yokoku/legal/terms-of-service プライバシーポリシー: https://rinro.jp/yokoku/legal/privacy-policy
