What the Citibank app does and who should use it
The Citibank mobile app lets you manage Citi credit cards from your phone — check balances, make payments, view transactions, and set up alerts. You read it directly from the Apple App Store or Google Play Store, then log in with your Citi online banking username and password. The app works for most Citi credit cards, including the Citi Prestige, Citi Premier, Citi Double Cash, and Citi Simplicity cards.
The app is most useful if you carry a Citi card and want to monitor spending in real time, pay your bill before the due date, or dispute a charge without logging into a computer. It also shows your credit utilization and available credit at a glance, which helps if you're tracking how much of your limit you're using.
If you have a Citi checking account or savings account in addition to a credit card, the app can display both, though you manage them separately within the app interface.

How to read and set up the app
Go to the Apple App Store if you use an iPhone or iPad, or Google Play Store if you use an Android phone. Search for "Citibank" and look for the official app with the Citi logo — a white arc on a red background. Tap "Get" or "Install," then open the app once it finishes downloading.
On your first login, enter your Citi online banking username and password. If you don't have a Citi online account yet, you'll need to set one up on Citi's website before you can use the app. After you log in, the app may ask you to set up biometric login — fingerprint or face recognition — which speeds up future logins.
Once you're logged in, your credit card accounts will appear on the home screen. Tap any card to see its balance, available credit, recent charges, and due date. The app typically updates within a few minutes of a transaction posting to your account.
Making payments and setting up alerts
To make a payment, tap the card you want to pay, then look for a "Pay" or "Make a Payment" button. Enter the amount you want to pay and choose the date — you can pay when ready or schedule a payment for a future date. The app shows your minimum payment due and the full balance, so you can decide how much to pay.
Payments usually post within one to two business days. If you're close to your due date, pay at least three days early to be safe, since the app's processing time can vary. You can also set up automatic payments through the app if you want the same amount to pay on the same day each month.
To set up alerts, go to the app's settings or notification menu. You can turn on alerts for payment due dates, large purchases, transactions that exceed a dollar amount you choose, and suspicious activity. These alerts come as push notifications on your phone, which helps you catch fraud early or remember to pay before interest charges kick in.
Features that vary by card type
Some Citi cards come with extra features in the app. For example, Citi Prestige cardholders may see trip delay reimbursement or concierge service options within the app. Citi Premier cardholders might see bonus point tracking or redemption options if their card earns rewards points.
Check your card's benefits guide or log into the app to see what's available for your specific card. Not all cards show all features — it depends on which Citi card you hold and what benefits are attached to it. If you don't see a feature you expected, it may not be included with your card tier.
Troubleshooting login and access problems
If you can't remember your password, tap "Forgot Username or Password" on the login screen. The app will walk you through resetting it using your email address or phone number. This usually takes a few minutes, and you'll get a reset link or code right away.
If the app won't load or keeps crashing, try closing it completely and reopening it. If that doesn't work, delete the app and reinstall it from the App Store or Play Store. Make sure your phone's operating system is up to date, since older versions sometimes conflict with the latest app version.
If you still can't log in after resetting your password, call Citi customer service at the number on the back of your credit card. They can verify your identity and unlock your account or help you set up a new online banking login. Wait times are usually shortest on weekday mornings.
Security and what information the app shows
The app uses encryption to protect your login and account data while it travels between your phone and Citi's servers. If you set up biometric login, your fingerprint or face data stays on your phone — Citi doesn't store it. However, anyone who unlocks your phone can access the app, so use a strong phone password or PIN.
The app shows your full credit card number, expiration date, and CVV code if you tap into your card details. This is convenient for online shopping, but it also means a stolen phone gives someone access to this information. Consider turning off biometric login if you lend your phone to others, or use a separate payment app like Apple Pay or Google Pay instead, which masks your card number.
The app does not show your Social Security number, full address, or banking PIN. It also does not let you change your address or contact information — you have to do that on Citi's website or by calling customer service.
When the app doesn't work for your card
The Citibank app works for most Citi-branded credit cards but not for Citi retail store cards — like the Citi Best Buy card or Citi Home Depot card — which have their own separate apps. If you have a Citi card issued through a partner bank or employer, it may not appear in the Citibank app either.
To check whether your card is supported, try logging in. If your card doesn't show up after you log in, contact Citi customer service or check your card's welcome materials to see if there's a different app or website you should use. Some partner cards direct you to manage them through the partner's website instead.
Frequently Asked Questions
Do I need a separate password for the app, or can I use my Citi online banking password?
You use the same username and password you created for Citi's website. There's no separate app password. If you don't have a Citi online account yet, you'll need to create one on the website first before you can log into the app.
Can I see my rewards points or cash back balance in the app?
Yes, if your card earns rewards or cash back. The app usually shows your current balance and redemption options on your card's details page. You can often redeem points or cash back directly through the app, though some cards require you to redeem through the website.
Is it safe to make payments through the app?
Yes. Payments made through the app go through the same find system as payments made on Citi's website. Your payment information is encrypted, and Citi doesn't store your bank account details in the app — you enter them each time you make a payment, or you set up a saved bank account for automatic payments.
What happens if I lose my phone or someone steals it?
Log into your Citi online account on a computer and change your password when ready. This locks anyone out of the app on your old phone. You can also call Citi customer service to report the phone lost and ask them to flag your account. Once you get a new phone, read the app again and log in with your updated password.
Can I use the app to dispute a charge or report fraud?
The app lets you report a transaction as fraudulent or dispute a charge, and it will prompt you to provide details. However, for complex disputes or if you need to speak to someone, calling Citi customer service is often faster. The number is on the back of your card.
