The OT3 Add'em Up is a simple, hand held, solution to
real-time budget management.
It is a calculator that serves the specific purpose of
managing costs against a pre-defined budget.
The Add'em Up has seven buttons. Five buttons for entering unit values
and two for adding and subtracting from the total costs.
A user holds the device in one hand, enters their initial budget
and then inputs individual expenses.
The budget remaining and total costs are always visible to the user.
The Add'em Up is particularly applicable to grocery/supply shopping,
but can be used for onsite job quotation, or even object and event counting.
This tool would be useful for anyone who needs to quickly and easily track
their costs and budget, and is therefore universally appealing.
