Prayer Times Calculator

High-precision astronomical calculation app designed to provide accurate prayer times, interactive graphical trends, Qibla direction, and lunar crescent predictions for Muslims anywhere in the world.

Whether at home or traveling, the app automatically determines your location coordinates and elevation to deliver highly accurate calculation results based on standard Islamic juristic conventions and astronomical algorithms.

Key Features:
- Precise Prayer Times: Computes daily times for Fajr, Sunrise, Dhuhr (Jumu'ah), Asr, Sunset, Maghrib, Isha, Midnight, and Imsak.
- Interactive Prayer Times Graph: Visualize annual or custom-range prayer time shifts with smooth interactive curves. Touch-swipe across dates to view exact time tooltips. Maximizing the chart automatically switches screen orientation to Landscape for a full-bleed visualization.
- Multiple & Custom Calculation Methods: Includes presets for Umm Al-Qura (Makkah), Muslim World League (MWL), ISNA, Egyptian General Authority of Survey, Gulf Region, University of Islamic Sciences (Karachi), Al-Awail (Syria/Lebanon), Moonsighting.com, and manual offsets. Built-in Calculation Methods Manager allows creating and saving your own fully custom calculation methods.
- Juristic Settings: Supports both Standard (Shafi'i, Maliki, Hanbali) and Hanafi Fiqh methods for Asr prayer calculations.
- High-Detail Qibla Finder: Integrated compass and interactive map with building-level zoom linking your current location directly to the Holy Kaaba in Makkah.
- Moonsighting & Crescent Predictor: Simulates and predicts lunar crescent visibility at sunset using Yallop (1997) and Odeh (2004) astronomical criteria. View the rendered shape of the crescent and detailed astronomical parameters (moon age, lag time, elongation, conjunction).
- Global Visibility Maps & Custom Criteria: Generate and explore interactive visibility maps showing observation zones worldwide. Built-in Criteria Manager enables adding and fine-tuning custom crescent visibility algorithms and mathematical coefficients.
- Custom Adhan Notifications & Quick Mute: Choose between Sound, Vibrate, or Muted alerts for each prayer. Upload your own custom audio files (.mp3). Mute playing Adhan audio instantly by pressing any physical side button (Volume+, Volume-, Power) or via ongoing status bar notifications.
- Serve to LAN: Host and share an electronic prayer times board on your local Wi-Fi network, allowing you to display the clock and countdowns on any Smart TV or monitor in your home or mosque.

- Beautiful Premium Design: Modern, intuitive interface supporting both Light and Dark modes.
- Fully Bilingual: Seamlessly switch between English and Arabic.
