A credit card tracker that never asks for a bank login
Last reviewed
A credit card tracker keeps the facts a statement does not put in front of you: when each card closes, when each is due, how much of each limit is used, and how close each reward rate is to its cap. It does not need read access to your bank accounts to do any of that. Entering the cards yourself takes a few minutes once and removes the whole question of who can see your accounts.
Why a tracker does not need your bank login
Aggregator-based apps ask for your online banking credentials so a third party can pull your transactions. That is a real convenience, and it is also a standing permission for an outside company to read your accounts, held for as long as the link lives.
Almost nothing a card tracker does needs that access. Statement dates, due dates, credit limits, APRs and reward terms are printed on your statement and your card agreement, and they change rarely. Balances change, but you already see them. A tracker built on numbers you enter yourself gives up automatic transaction import and gets back the entire category of risk that comes with handing over bank credentials.
What a credit card tracker should actually track
Four things carry almost all of the value, and every one of them is knowable without touching your bank.
- The statement date of each card - the day the bill is calculated and, usually, the day your balance gets reported to the bureaus.
- The due date of each card, and whether paying the statement balance in full will keep the interest-free grace period alive.
- Utilization per card and across all cards, since the figure that gets reported is the one standing on the statement date, not the one on the due date.
- Reward caps: how much of each bonus rate is still available this month or quarter, because a spent cap changes which card is worth using.
What you give up, stated plainly
A manual tracker will not notice a purchase you did not tell it about. You enter spending yourself, or hand it a statement PDF or screenshot that is read on the device into a review list you approve. Nothing lands in your balance until you accept it.
In exchange there is no bank login, no real card number, no CVV and no server holding your accounts. By default the data does not leave the phone at all; iCloud sync is optional and goes to your own iCloud rather than to us.
What CardLab tracks, and where it works
CardLab is that tracker for iPhone. It holds your cards with their real terms, shows the billing cycle as a timeline rather than a list of dates, tracks utilization and reward caps, and runs payoff and interest scenarios on your own numbers. The tracker and its simulators work in all 40 of its country presets, because they compute from the terms you type in. The verified card catalog - the part that can rank cards for a purchase - covers 17 markets.
Without paying anything you get: two cards you enter by hand, in one country; timeline, payoff & utilization labs; 5 core lessons.
How to judge a credit card tracker
The tests below apply to any tracker. The answers are CardLab's, and each is checkable on the page it links to.
Where does the data live?
On your device by default. CardLab runs no database of user data. Optional iCloud sync stores it in your own private iCloud, managed by Apple. Deleting the app, or Settings then Delete all data, erases it.
What does it ask for to get started?
No account, no email, no sign-in and no bank connection. The app works fully offline.
Does it sell or share what it sees?
No ads, no trackers and no data sold. The only thing collected is the App Store purchase record Apple reports, which carries no identity.
Does it explain the numbers or just display them?
Every figure is backed by a simulator you can open: interest by the average daily balance method, grace gained and lost, minimum payments with negative-amortization warnings, and payoff comparisons.
Does it handle your currency and your country?
40 country presets, locale-aware currency including zero-decimal yen and won, and 34 languages.
Runs in the browser with nothing to install, so you can see how the tracking math behaves before putting your own cards in.
Common questions
Is there a credit card tracker that does not need a bank login?
Yes. A tracker that you enter cards into yourself needs no bank connection at all, because statement dates, due dates, limits, APRs and reward terms come from your statement rather than from a transaction feed. CardLab works this way: no bank login, no card number, no CVV, and nothing sent to a server.
How do I track multiple credit cards?
Record each card with its own statement date, due date, credit limit, APR and reward terms, then watch them as one calendar rather than as separate bills. The thing that goes wrong with several cards is not arithmetic, it is dates: two cards closing a week apart report utilization at two different moments.
Is a manual credit card tracker safe?
It removes the main risk of automatic trackers, which is giving a third party standing read access to your bank accounts. With a manual tracker the data is whatever you typed, and with CardLab it stays on your device unless you turn on iCloud sync, which goes to your own iCloud account.
Can CardLab read my statement so I do not have to type it?
Yes, on the phone. Hand it a statement PDF or a screenshot and it reads the rows on the device, with no bank login and nothing sent anywhere. Every row waits in a review inbox until you accept it, so nothing changes your balance, utilization or rewards until you say so.
Does tracking my cards in an app affect my credit score?
No. A tracker is a record you keep; it is not a credit application and it is not visible to a lender or a bureau. CardLab shows an educational Credit Health Meter, which is not a credit score, and it does not calculate, predict or report one.
