Goldify Android App
Gold Rate & Converter — Live Rates, Universal Converters & Shop Records on Google Play
Overview
Goldify is the native Android companion to the Goldify Pro web platform, published on Google Play under developer Muhammad Salman Saleem. Built with React Native and Expo, it auto-detects the user’s country to surface local gold rates, then layers on the full professional toolkit: per-tola and per-gram karat rate tables, a universal converter that maps any unit to any other (grams, tola, masha, ratti, ounce, troy ounce, pennyweight, grain, kilogram), purity and average-rate calculators, a gold analyzer, and a shop record module for jewelry sales, gate history and gold books. Google Sign-In keeps records tied to the user, and the app ships monetized through Google AdMob with a verified app-ads.txt on this domain.
Problem & Solution
Jewelers and gold traders work off the phone at the counter, but the tools they need are split across websites, calculator apps and paper registers — and almost none of them handle local rates, South Asian units like tola, masha and ratti, or day-to-day shop records.
Goldify puts the whole counter workflow in one Android app: country-aware live rates, a universal converter covering both metric and traditional units, karat and purity calculators, and an on-device shop record book — installable free from Google Play.
