Sunnah & Obligatory Fasts
Full coverage of Ramadan plus the major Sunnah fasts — Monday/Thursday, Ayyam al-Bid, Ashura, Arafa, Six of Shawwal, and the first eight of Dhul-Hijja. Each day is identified automatically from the Hijri calendar.
Every fast, tracked with intention.
صيام (Siyam) is a private, Arabic-first iOS companion for Ramadan, Sunnah fasts, and intermittent fasting. Hijri calendar, accurate prayer times, and gentle on-device reminders for Suhoor, Imsak, and Iftar — all offline, all on your iPhone.
Core Features
Fasting, simplified.
Everything you need to plan, observe, and reflect on your fasts — designed for both worship and wellness.
Intermittent Fasting Protocols
Built-in support for the most common IF schedules — 16:8, 18:6, 20:4, and OMAD — with a clear fasting/eating window timer. Switch between religious and health modes any time.
Hijri Calendar
Built around the Umm al-Qura Hijri calendar with a beautiful month view. See sunnah days, Eid days (when fasting is forbidden), and Ayyam at-Tashreeq highlighted at a glance.
Accurate Prayer Times
Suhoor, Imsak, Fajr, Maghrib, and Iftar — calculated from your location with multiple methods (Umm al-Qura, MWL, Egyptian, Dubai, Qatar, Kuwait, North America, Karachi) and Shafi/Hanafi madhab.
Smart Local Reminders
Optional gentle nudges before Suhoor and just before Iftar, plus a Maghrib adhan with the bundled muezzin sound. Every notification is scheduled locally — no server, no tracking.
Privacy First
Your fasting log lives on your device — no account, no cloud sync, no profiling. We don't track you across other apps and fully comply with Apple's App Tracking Transparency framework.
Why Siyam
Built for worship and wellness.
Two modes, one app — designed with care for everyday Muslims and anyone curious about intermittent fasting.
Religious Mode
The full sunnah toolkit — Ramadan, Monday/Thursday, Ayyam al-Bid, Ashura, Arafa, Six of Shawwal, the first eight of Dhul-Hijja, plus voluntary days. Forbidden and discouraged days are clearly marked.
Intermittent Mode
Switch into health mode for time-restricted eating. Pick 16:8, 18:6, 20:4, or OMAD and watch your fasting and eating windows progress on a clean dial.
Arabic-First, RTL Native
Right-to-left layout, native Arabic typography, and Hijri-aware date formatting throughout. Notifications are locked to RTL even on English-locale devices so the text always reads correctly.
Bundled Adhan
An optional Maghrib adhan plays through the included muezzin sound, scheduled locally on your device — no streaming required.
Calendar & Stats
Browse a month view, tap any day to log, and review your streaks and totals over time. Religious and IF logs stay clearly separated.
Universal App
Optimized for iPhone with adaptive typography and dark/light themes. iOS 17 and later.
