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, Core2 CRM with Invoices or CheckTracker, which might be similar to Totalus.
