DailySync is a modern and powerful smart reminder & daily planner app source code designed to help users manage tasks, schedules, and reminders across multiple popular applications from one place.

With DailySync, users can create reminders for actions such as sending WhatsApp messages, making phone calls, checking Gmail emails, sending SMS or Telegram messages, writing notes, or navigating to a specific location using maps. Each reminder triggers an intelligent notification that opens the selected app or action at the right time or location.

The app focuses on productivity, ease of use, and performance. It features a clean UI, smooth animations, intuitive navigation, and full support for Light Mode and Dark Mode, ensuring a premium user experience.

This project is built using React Native (Expo 53, React Native 0.79, React 19) and comes with a clean, modular, and well-structured codebase. It is fully customizable, easy to rebrand, and ready to be published for both Android and iOS platforms.

DailySync is an ideal solution for developers, startups, and businesses looking to launch a productivity, reminder, or task management application quickly.
