The struggle is real

Multiple cards shouldn’t mean more confusion.

You’re not bad at rewards. Cards are just complicated.

🤯

Too many rules

Remembering which card gives 5% on travel vs 2% on dining is impossible at the checkout counter.

💸

Different rewards

The same ₹1,000 purchase could earn you ₹50 on one card and ₹10 on another. Don't leave money on the table.

🛡️

Picking "Safe"

You often pick a default card just to finish the payment, missing out on superior returns every single time.

3 steps. Zero confusion.

Frequently Asked Questions

Is PaySmarter really free? +
Yes, PaySmarter is a completely free tool designed to help users get the most out of their existing cards.
Do I need to enter a merchant? +
No. Merchant is optional. While it improves accuracy (as many cards have merchant-specific rewards), the amount alone works for general categories.
Do you store card numbers? +
No. We only store the names of the cards you add (e.g., "HDFC Millennia") to calculate rewards based on public bank rules.
Is this financial advice? +
No—this is a rewards optimization helper. We only help you decide which card to pull out of your wallet for a specific spend.
What if card rules change? +
We constantly monitor bank updates and keep improving our coverage and logic to ensure accuracy.
