Apps for checking the balance of Octopus

I finally found the best app of the year.  It is the Octocheck (Octopus Card NFC Reader), an app for checking the balance of Octopus Card with the  last 10 trading date, time, nature of the transaction and the amount of information.  

It is available from Google Play at :

The smartphones and tablets must have NFC functionality.  My son's smartphone Xperia Ion has this feature so one installation should be sufficient for the whole family.

There are 13 million Octopus Cards actively used by consumers every day.  This app comes a bit late.  Anyway, still need to say thanks to Octopus Cards Limited for developing an useful app.  This might be the first large scale application of NFC in smartphones for Hong Kong people.
