Overview

TBOU is a feature-rich notes and journaling app that combines powerful text editing capabilities with seamless cloud synchronization. The app serves as a complete productivity solution for capturing thoughts, managing to-dos, and organizing information with rich text formatting and multimedia support. Built with Swift and CoreData, TBOU implements a sophisticated offline-first architecture that stores all notes locally with automatic server synchronization via Alamofire REST APIs. Users can create and edit notes with advanced text formatting including highlights, bold text, headers, bullet points, and custom attributes using NSMutableAttributedString. The app features intelligent link detection during typing, OCR-powered image scanning to extract text from photos, and drag-and-drop functionality for organizing content across table and collection views. Integration with iOS Calendar Events and Reminders allows users to set deadlines and schedule tasks directly from notes. The app supports both local and remote push notifications for timely reminders. Security is prioritized with biometric authentication (Face ID/Touch ID) for app access.
