Find mosques, halal food, and prayer times — all in one place.
Muslim Atlas is a mobile application built for the Muslim community in the UK and beyond. It brings together mosque finding, halal food discovery, and accurate Islamic prayer times into a single, clean, and fast experience.
The app is designed to be genuinely useful day-to-day — whether you need to find the nearest mosque on the go, check when Asr is today, or locate a halal restaurant nearby. It runs without ads and without subscriptions.
The Muslim community deserves tools built specifically for them, not adapted from generic apps. Muslim Atlas aims to become the go-to companion app for Muslims navigating their daily lives — starting with the UK and expanding globally.

- iOS release
