"bundla" is for working out quantities of items for individual areas and the overall total amounts. It was designed to save time calculating the amounts.
How to use:
Just enter the total amount in the "Amount" column for each area.
If an area is not going to be used, just leave it blank or enter "0".
Navigate between the tabs at the bottom to enter a second type of bundles.
Tap the "Calculate" button on each page and the number of bundles and/or loose items will appear next to each area.
