Muslim’s Adhkar – Hisn Al-Muslim PWA

Muslim’s Adhkar is a modern offline-first Progressive Web App (PWA) designed for daily worship. It brings together three essential tools in one lightweight experience:

• Hisn Al-Muslim (Fortress of the Muslim) adhkar with audio
• Accurate prayer times with notifications and Qibla direction
• A complete Quran reader with recitations and ayah highlighting

After the first load, the app can work fully offline, making it ideal for travel, weak networks, and daily use.

Who This App Is For

• Muslims who want fast access to authentic daily adhkar
• Users who need reliable prayer times based on location and method
• Anyone looking for an offline Quran reading and listening experience
• Communities and organizations that want a lightweight Islamic PWA
