TalaYar helps estimate the cost of buying new gold and calculate trades involving pre-owned gold, melted gold, and coins. Use the app’s online rate or enter a manual rate, then add the weight, karat, and applicable charges to view an estimate. The free version includes the new-gold purchase calculator; the other sections, transaction history, guides, and backup features are unlocked with a one-time in-app purchase. Calculations are estimates, so confirm the final amount with the seller and the transaction invoice.
