Abstract
Task management applications are widely used for personal productivity and reminder scheduling. However, many existing solutions depend on cloud services and account synchronization, which may be unsuitable for offline or privacy-sensitive environments. This study presents a Unity-based offline task management application that integrates JavaScript Object Notation (JSON)-based local storage and Android local notifications. The objective is to evaluate the feasibility of using Unity, a game engine, for a non-gaming mobile productivity application. The system supports task creation, browsing, deletion, local data persistence, and scheduled notifications. Experiments on an Android smartphone evaluated notification reliability, notification delay, storage performance, and resource consumption. Results showed notification success rates of 100.0%, 96.7%, and 93.3% in foreground, background, and screen-locked conditions, respectively, with average delays ranging from 0.42 s to 3.21 s. JSON read/write operations remained below 20 ms for up to 500 tasks. The Android Package (APK) file size was 39.9 MB and 121 MB after installation. The findings indicate that Unity is a feasible platform for lightweight offline task management applications, although trade-offs exist in resource usage and local storage security.
