The 1.1 version of Totalus for Mac was available as a free download on our website. The application lies within Business Tools, more precisely Finances.
From the developer:
Totalus is essential: We all have to calculate something everyday, e.g. planning of shopping, summing up of receipts, counting of calories, etc. Most of such a calculation just has a simple form of summation of multiplication results.
You may want to check out more Mac applications, such as EuroConverter, Merchant Wisdom or CheckTracker, which might be similar to Totalus.
