Salah Pro — Muslim Prayer Reminder (Mobile + Desktop + Extension)

Salah Pro is a complete cross-platform Muslim prayer reminder ecosystem built across three platforms from a single codebase vision: a React Native mobile app (Expo), an Electron desktop app, and a Chrome/Firefox browser extension.

All three platforms share the same core feature set: GPS-based accurate prayer times using the user's live location (ipapi.co geolocation), Azan audio notifications for all five daily prayers (Fajr, Dhuhr, Asr, Maghrib, Isha), Qibla compass direction, customizable calculation methods (MWL, ISNA, Egypt, Makkah, Karachi), and a clean Islamic-themed UI.

The React Native mobile app (Expo Router, EAS Build) delivers a native experience on iOS and Android with animated prayer countdown timers, full settings panel, and dark/light themes. The Electron desktop app (electron-vite, Vite + TypeScript) runs as a system tray application — prayer time popups appear above all other windows and play Azan through the system audio. The Chrome extension (Manifest v3, service worker) adds prayer times to the browser toolbar popup with one-click Azan on/off toggle and a full settings page accessible from the extension options.

All three apps support: multiple calculation methods, Hanafi/Standard Asr calculation, custom Azan audio upload, hijri calendar display, and city-name override. The mobile app additionally includes a full Qibla compass with animated needle. Designed and built as a potential App Store and Chrome Web Store product.
