How to track GTBank transactions automatically

GTBank already texts you every time money moves. PennyWise reads those messages on your phone and builds your spending record from them — no manual entry, no bank login, nothing leaves the device.

How it works

  1. Install PennyWise and grant SMS permission. That permission is the whole product — it is how the app sees your GTBank alerts.
  2. PennyWise scans the GTBank messages already on your phone and back-fills your transaction history in seconds.
  3. Every new GTBank alert is picked up as it arrives and categorised automatically. Budgets and spending trends update on their own.

What PennyWise reads from your GTBank messages

Everything above is extracted by an on-device parser written specifically for GTBank's message formats. You can see it run on your own message, without installing anything: open the parser tool and paste in one of your GTBank messages.

Why not just use a bank-login app?

Apps that aggregate accounts ask for your net-banking or account credentials and hold your transaction history on their servers. PennyWise asks for neither. It has no account system, makes no network calls to read your money, and its full source is published under AGPL-3.0 so the claim is checkable rather than promised.

Common questions

Does PennyWise work with GTBank?

Yes. GTBank is one of 157 banks and payment services PennyWise recognises. Transaction alerts from GTBank are detected automatically and turned into categorised transactions in NGN.

Do I have to type my GTBank transactions in by hand?

No. PennyWise reads the transaction SMS GTBank already sends you and creates the entry itself — amount, merchant, date, account and running balance where the message includes it.

Does PennyWise need my GTBank net-banking login or password?

Never. PennyWise has no login to your bank and no connection to GTBank at all. It only reads the SMS already sitting on your phone, which is why it needs SMS permission and nothing else.

Is my GTBank transaction data sent anywhere?

No. Parsing runs entirely on your device. There is no server, no account and no analytics on your financial data, and the source code is public so this can be verified.

What if a message from GTBank is read incorrectly?

You can paste the message into the parser tool on this site to see exactly what PennyWise extracts, and report it in one click if it is wrong. Parser fixes ship in the next release.
