SwarnaPro
The gold calculator and udhaar book for jewellers.
SwarnaPro does the two jobs a jeweller repeats all day. It prices old gold, new jewellery and exchanges with the trade's real rules - purity, wastage, making charges, and GST on making charges only when it's an exchange. And it keeps the udhaar: record what the customer actually handed over and the rest becomes a balance against their name, so the khata lives in your pocket instead of a notebook. Payments settle the oldest charge first, overdue customers rise to the top, and a polite WhatsApp reminder is one tap away. Everything runs on the device - no account, no server, nothing collected.

Everything SwarnaPro does well.
Udhaar book
Every customer's balance, overdue first, with a one-tap WhatsApp reminder.
Part payments
Enter what was handed over; the rest becomes udhaar automatically.
Buy, sell, exchange
Purity, wastage and making charges, with GST applied the way the trade bills it.
Yours alone
No account, no server. Every record stays on the phone, with backup and restore.
A calculator is replaceable; a ledger is not. Jewellers were already doing the math on paper and carrying half the shop's accounts in their head - so the real product was never the arithmetic, it was remembering who owes what. Getting the domain rules exactly right, down to GST applying only to making charges in an exchange, is the whole value.

Good to know.
What is udhaar?
The running credit a shop extends to a regular customer - the khata. SwarnaPro keeps that balance for you: record a part payment on the sale and the remainder is tracked against that customer until it's settled.
Does my customer data leave the phone?
No. SwarnaPro has no account and no server. Customer names, balances and transactions are stored on your device only, and nothing is collected or shared.
Is there a subscription?
No. The app is free, with no subscription and no in-app purchases.
What happens to my data if I change phones?
Create a full backup from Settings and restore it on the new device. A restore always saves a rollback copy first, so a mistaken restore can be undone.
