An app that may be phishing.
This is the support available for this app:

The application advertises that it can email csv files with your expenses to you, it does not do this. It is also supposed to be able to sync with google docs. It does not do that either. BTW you must enter your gmail account and password info into the app. Shortly after I did this I was notified by google that my account had been accessed in India and I should change my password immediately. I would have to say that this app does not do what it is supposed to do and you may be at risk of being hacked if you enter other account info into this app.
