Discovery

Project Overview

Halal Advisor is a food discovery and review application designed to help users find Halal-certified restaurants based on cuisine, location, and user reviews. The platform serves a younger, mobile-first audience looking for reliable Halal dining options with accurate location data, ratings, menus, and offers.

The client partnered with Jhavtech Studios to rescue and stabilise an already launched application that was facing functional, performance, and user-experience issues across both iOS and Android platforms.
