「時計を、変えるだけ。いつもの作業が速くなる。」 倍速時計は、秒針が1.5倍速で動くアナログ時計アプリです。 "針を1.5倍速にしても、感じるストレスは変わらず、作業量だけが増えた" という研究に着想を得ました。 ■ 使い方は2通り ・デスクに置いて、時計を見ながら作業する ・画面を伏せて、秒針の音を聴きながら作業する 時計が見えない場所でも、音だけで使えます。 ■ 夜は0.5倍速 ゆっくり刻む秒針を、読書や夜のひとときに。 時間を"引き延ばして"眺める、もうひとつの使い方です。 ■ 時間を決めて、はじめる(ポモドーロ対応) 25分・45分・60分から選んで、ひと押しで始められます。 25分はポモドーロ標準の長さ。作業と休憩をくり返す設定にも対応しています。 残りは輪が欠けていく形で見えるので、数字を読まなくても分かります。 画面を消しても、時間は正確に測り続けます。 ■ 秒針の音までこだわり 音の高さ、こもり具合をスライダーで調整できます。 本物の壁掛け時計のような音から、澄んだ軽やかな音まで。もちろん無音にも。 ■ 特徴 ・登録不要・広告なし・オフラインで使えます ・ホーム画面ウィジェット / StandBy(ベッドサイド時計)対応 ■ 無料でできること ・秒針の速度を 0.5x / 1.0x / 1.5x から ・秒針の音の高さ、こもり具合の調整 ・ポモドーロタイマー(25分・45分・60分/作業と休憩のくり返し) ・ウィジェットとStandBy ■ 買い切りProでできること ・速度を 0.5x〜3.0x の14段階から自由に ・文字盤をローマ数字・バー・メルヘンから ・針と数字の色、壁の色、背景写真を自由に ・秒針音のプリセット ・タイマーの時間を1分単位で。くり返す回数と休憩の長さ、終わりの音も ・ウィジェットにも見た目を反映 一度きりの買い切りです。サブスクリプションはありません。
