ZzZlapp is a native iOS application built entirely with SwiftUI that replaces traditional alarm systems with mandatory cognitive and physical "wake-up missions." The app follows a 100% local architecture, utilizing CoreData for data persistence and user metric tracking, ensuring all processing and storage happen on-device without external server dependencies or login requirements. The technical core of the application involves the implementation of Apple's AlarmKit framework to ensure alerts bypass Silent Mode and Focus profiles, a process that required navigating complex and recently released technical documentation. For physical missions such as squats and pushups, the app integrates Vision Framework and ARKit for real-time body tracking and computer vision gesture detection. Additionally, the app features a robust scheduling engine that manages a chain of up to 20 pre-scheduled backup alarms at 1–5 minute intervals. This logic is specifically designed to remain persistent and fire automatically even if the application is force-quit or the device is locked. I led the entire development and engineering lifecycle, collaborating with a dedicated designer for the UI and branding, to deliver a high-performance product that manages concurrent motion sensor processing, real-time image analysis, and critical system notifications.
