The idea

One number, two metals.

The Gold–Silver Ratio is how many grams of silver equal one gram of gold. Enter today’s prices in rupees per gram and the app shows the ratio instantly, as one large, clear number.

Portfolio

Your holdings, at a glance.

Add your grams and average buy prices to see invested and current value, profit and loss, your gold-to-silver allocation and an action plan towards your target mix.

Averages

Many purchases, one average.

Log purchases across dates and prices; the weighted average buy price is worked out for you and sent to the portfolio in one tap.

Principles

Private, offline, honest.

No accounts, no subscriptions, no data feeds — everything stays on the device and works offline. A built-in guide explains the ratio, and the app is clear that it is an educational tool, not investment advice.
