An unusual clock app that allows you to be more productive by making friends with "time". The design is highly customizable. Also ideal as a table clock. [ Increase Free Time ] Why is there only 24 hours a day? This app allows you to change the length of time. If you set a day to 26 hours, the length of one hour will be 5 minutes shorter than usual. By putting this clock in a place where you can see it, you will be able to spend your time efficiently in a natural way. After 24 hours, you will get 2 hours of bonus time. This means that the short times you save will be combined to make more meaningful time. [ Take Frequent Breaks ] Proper breaks are essential for meaningful use of time. You need to stand up, stretch and hydrate regularly. If you set 1 hour to 65 minutes with this app, you can take a 5 minute break every 60 minutes. You can also ring the chime every hour, which makes it easier to take a break even if you are absorbed in the work. [ Fits Your Lifestyle ] Do you have the habit of advancing the clock in your room? This is usually not possible with a “too accurate” clock on a smartphone. With this clock app, you can advance or delay the display time. If you advance it by 5 minutes, you will be able to avoid being late. You can also set the start time of the day. For example, you can manage working hours by setting the business start time to 00:00. When traveling, it's easy to set the clock to local time. [ Also as a Table Clock ] Of course, this app can also be used as an ordinary clock. It has a big, easy-to-read digital display, so it's a good idea to use it as a table clock when your iPhone or iPad is on a charging stand. You can change the design of the clock face by setting the font and background. Enjoy customization. [ List of Functions ] Clock: - Advance or delay the clock. - Set the start time of the day. - Set the hours per day, minutes per hour, and seconds per minute. - Accelerate the clock up to 24x. - Sound the chime every hour/minute/second.

「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。

Verdict

The call

The clearest difference is ads: 倍速時計 at none against Chronomagic's shown. 倍速時計 also leads on update cadence (every 3 weeks vs every 5 months). Chronomagic's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price and in-app purchases there is nothing between them.
