Introducing "Perk", a simple rewards tracker for your credit cards

Are you tired of tracking all those credit card rewards that reset every month, every quarter, every calendar year, and every anniversary year?

Perk is the perfect service for you! Link: https://perkkk.vercel.app

Why?

Here is the thing about modern credit cards: the annual fee only makes sense if you actually use the credits. But every card resets on a different schedule — $10 DoorDash credits every month, Resy credits every quarter, hotel credits on calendar years, free night certificates on anniversary years. Issuers know you will forget. That is the business model.

What it does

Perk puts every credit from every card you hold on one screen, sorted by how soon they expire. Mark a credit as used, and it tracks how much value you have recovered against each card’s annual fee this year.

It also handles the meta-game:

• Signup bonus cooldowns — when you are eligible for the next bonus
• Your Chase 5/24 count
• Annual fee dates
• Spend milestones, like Delta’s $10k eCredit

No card numbers, no bank linking, no transaction data — it only knows which cards you have and which perks you have used.

Both English and Korean are supported — use the toggle at the top right to switch.

How to use

Head over to perkkk.vercel.app, sign in with Google, add your cards, and start checking off credits. That is all.

How it was built

And yes, I built this fully vibe-coded. That said, I did spend a lot of time designing the cards and their animations.

Credit card rewards change every day. For instance, the Delta Amex cards were refreshed just last week, and Chase Sapphire Preferred announced changes today.
