Help for Financisto

A help function in the app would be a good feature: if you don't have a computer nearby and can look up in the bolg how it works it's really difficult to find out how financisto works. Especially because the german translation lacks in some points, e.g. the translation of "closing day" and "payment day" isn't the best in my opinion: the german words "Letzter Zahltag" und "Zahlungstag" mean the same thing - I understood the intended meaning only by reading the english terms in the tutorial.
