Design and Development of a Self-Sabotaging Alarm Clock Mobile Application for Cognitive-Based Wake-Up Intervention

Oversleeping remains a common daily problem, not because alarms are unavailable, but because many existing alarm systems are too easy to silence during the low-alertness period immediately after waking. This study presents the design and development of a self-sabotaging alarm clock mobile application intended to reduce reflexive alarm dismissal by requiring cognitive engagement before alarm termination. The proposed system was developed as an Android-based application using a structured software development process that covered requirement analysis, interface design, implementation, and functional verification. Its core mechanism replaces one-touch dismissal with puzzle-based interaction, specifically math and memory challenges, so that the user must complete a task before the alarm can stop. For example, when the alarm rings at a scheduled time such as 7:00 a.m., the user is redirected to a challenge screen and cannot complete the wake-up workflow until the correct answer is entered. The application also includes alarm scheduling, user customization, and cloud-backed storage for alarm attributes such as hour, minute, label, and enabled status. The resulting prototype demonstrates that a conventional alarm workflow can be restructured into a more deliberate and cognitively demanding sequence. Although the present study does not report a long-term user trial, it establishes a working mobile prototype and a clear implementation pathway for future behavioral evaluation of wake-up compliance, dismissal time, and user retention.赖床仍是常见的日常困扰，其根源并非缺乏可用闹钟，而是多数现有闹钟系统在唤醒后即刻的低警觉状态下，极易被误触关闭。本研究设计并开发了一款自我阻碍式闹钟移动应用（self-sabotaging alarm clock mobile application），旨在通过要求用户完成认知任务后方可关闭闹钟，减少用户下意识取消闹钟的行为。所提出的系统采用结构化软件开发流程，基于安卓（Android）平台实现，覆盖需求分析、界面设计、代码实现与功能验证全环节。其核心机制将一键关闭闹钟的操作替换为基于谜题的交互形式，具体包含数学与记忆挑战，用户必须完成指定任务后方可终止闹钟。例如，当闹钟在预设时间（如上午7:00）响起时，系统将跳转至挑战界面，用户需输入正确答案后方可完成唤醒流程。该应用同时支持闹钟日程设置、用户个性化定制，以及针对闹钟属性（如小时、分钟、标签与启用状态）的云备份存储。最终产出的原型系统证实，传统闹钟的唤醒流程可被重构为更具主动性与认知负荷的序列操作。尽管本研究未开展长期用户试验，但已搭建出可运行的移动应用原型，并为后续针对唤醒依从性、取消闹钟耗时与用户留存率的行为评估，提供了清晰的实现路径。
