Octopus Balance Reader

First app to retrieve the balance of the HK Octopus Card, since 2011.
Once you own an NFC enabled android phone, you are eligible to use this app.

Thanks for support us for more than 10 years, the app is revamped to support modern Android version. With improved UX.

Able to read the balance offline!

This app will only read the data from the card. It will not modify any data on your card.

Thanks for your support! :)

Sound is emitted by the system, even after you uninstall this app. Android try to show you that no app is suitable to read your card.
