Features

⏱️ Intermittent Fast Tracking

  • Intuitive Timer: Start, stop, and adjust your fasts with a single tap. A persistent background service ensures your progress is tracked accurately, even if the app is closed or the device restarts.
  • Flexible Fasting Goals: Choose from standard intermittent fasting plans (16:8, 20:4, OMAD) or define a custom goal that fits your specific routine.
  • Visual Progress: Stay motivated with Material 3 Expressive countdowns and notifications.
  • Comprehensive History: Review past fasts with detailed logs and edit previous entries to keep your data accurate.
  • Streaks: Stay motivated by building up you fasting streaks, helping you build a habit.
  • Statistics: Visualize your streaks and habits over time to better understand your progress.

🎨 Personalization

  • Material 3 & Dynamic Colors: A modern Material 3 interface (using Material 3 Expressive components) that supports "Material You," automatically adapting to your system wallpaper colors.
  • Theming Support: Seamlessly switch between light and dark themes for comfortable nighttime logging.
  • UI Customization: Tailor the app's look with adjustable accent colors and interface elements.

🛡️ Privacy First

  • 100% Offline: FastTimes works entirely without an internet connection. Your data never leaves your device.
  • No Accounts, No Tracking: No email required, no cloud syncing, and absolutely no third-party analytics or trackers.
  • Open Source: Built with transparency in mind.
  • Full Data Control: You own your data. Export and Import your history as you wish.

🏗️ Modern Tech Stack

Built with the latest Android standards to ensure a high-performance, resilient experience:

  • Jetpack Compose: A fully declarative UI for fluid animations and a modern user experience.
  • Kotlin Coroutines & Flow: Powering reactive, non-blocking data streams throughout the app.
  • Room & DataStore: Robust local-first persistence; Room handles complex fasting logs while DataStore manages user preferences.
  • Hilt DI: Clean dependency injection for a modular, maintainable, and testable architecture.
  • Clean Architecture (MVVM): Ensure the app is scalable and robust.
