Find the best card offer before you pay.

Add the cards you own. Phronix matches live bank offers and hands you one ranked verdict — before you tap or swipe.

How it works

Three steps, no guesswork.

01

Add your cards

Tell Phronix which cards you carry — just the product, like "Commercial Bank Visa Signature." Never a card number.

02

Search a merchant

Type where you're shopping, or browse by category — dining, travel, shopping, groceries.

03

Get the verdict

Phronix ranks every matching offer by real savings and tells you exactly which card to use, right now.

See it in action

This is what "which card" looks like.

Get your verdict

Tell Phronix where you're shopping. It tells you exactly which card to use and how much you'll save.

Know what you're getting

Full terms, eligible cards, and expiry — one tap away from the offer's own bank page.

Beyond the obvious

It'll even tell you when a card you don't own would do better.

Every recommendation is checked against every active offer — not just the ones your cards qualify for. If a different card would clearly save you more, Phronix says so, plainly, right there in the verdict.

Track what you save

Watch the savings add up.

Mark an offer as used and Phronix adds the saving to a running total for the year — broken down by card, with a look at this week's activity. It's an estimate, based only on the offers you tell it you've used.

What you get

Everything a good decision needs.

Live bank offers

1,800+ active offers scraped from ten Sri Lankan banks, refreshed automatically in the background.

Bill calculator

Enter the amount on your bill and see the exact rupee saving — not just an advertised percentage.

Saved offers

Bookmark deals you want to remember, with reminders before they expire.

Savings tracker

Mark an offer as used and Phronix keeps a running total of what you've saved this year — broken down by card, with a quick look at this week's activity.

Favourite merchants

Star the places you shop often and get told the moment a new deal lands there.

Category browsing

Dining, shopping, travel, groceries and more — sorted by how much you'd actually save.

Home-screen widget

Your best card and saving, right on your home screen on Android and iPhone — pin it to a category, one of your cards, your saved offers, or your favourite merchants.

Lock & themes

Fingerprint or face unlock, with light and dark themes that follow your system or stay put.

The name

Practical wisdom, right when it matters.

Phronix comes from phronesis (φρόνησις) — the Greek word for practical wisdom: knowing the right thing to do, right when it matters. That's the idea behind every card the app recommends.

Never collected

Phronix never collects your card number, CVV, PIN, expiry date, banking credentials, OTPs, or transaction history. Only the name of the card product you own is ever stored.
