This App was created based on statistics and data. For university students, whether or not to get credits is a matter of great concern. Depending on the department and subject, students will often struggle because the weight of the evaluation of written tests, reports, practical tests, and attendance varies from subject to subject. University students are busy in many ways. "I'm so busy with my part-time job that I tend to miss a lot of classes." "I forgot to turn in a few assignments." "I partied a bit too much and now I'm struggling to keep up with my classes." "This class is a compulsory subject and must be taken for credit." This is the best solution for those who have such problems. If you know at an early stage whether you have a high or low probability of earning credits, you will be able to change how much effort you put into the class in the future. It will also give you a good opportunity to rethink the class as a whole, such as what you need to improve or what you need to focus on, if you think you may lose credits if you do not do so.

Debt Clockは、ただ時間を計るだけのタイマーではありません。あなたが設定した「理想のペース」と「現実の行動」の差分を計算し、サボった時間を「負債(Debt)」として可視化します。 負債を抱えたまま一日を終えるか、それとも完済してスッキリ眠るか。 あなたの自己規律が試される、全く新しい習慣管理ツールです。 【主な機能】 ・Time Debt System(時間負債システム) 目標時間に対して作業が遅れると、その差分が「負債」として積み重なります。負債を返済(リカバリー)するために、あなたはより集中する必要が出てきます。ゲーム感覚で自分を律しましょう。 ・Neo-Brutalism Design 流行の「ネオ・ブルータリズム」を取り入れた、高コントラストで力強いデザイン。余計な装飾を削ぎ落とし、あなたの集中力を極限まで高めます。 ・Fluid Wave Animation 時間の経過を「波」のアニメーションで表現。数字だけでなく、直感的に残り時間を感じることができます。ホーム画面ウィジェットにも対応。 ・Streak & Graph 継続日数(ストリーク)と日々のパフォーマンスをグラフ化。あなたの頑張りを視覚的に記録し、モチベーションを維持します。 ・Focus on Privacy 会員登録不要。すべてのデータはあなたの端末内に保存されます 利用規約 https://button-hardboard-dd1.notion.site/Debt-Clock-2026-2-4-2fdc16d080408079b377c256090ac220?source=copy_link プライバシーポリシー https://button-hardboard-dd1.notion.site/Debt-Clock-2026-2-4-2fdc16d080408079b377c256090ac220?source=copy_link

Verdict
The clearest difference is update cadence: Debt Clock at every 2 days against TanB's every 15 months. Debt Clock also leads on iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
