Such an app does exist in FareBot

The author of FareBot suggests "Removing detailed trip information
from these cards while keeping the balance readable without
authentication is a good compromise that balances privacy with
utility." http://codebutler.com/2013/02/14/farebot-transit-card-privacy-news/
