Instructions were easy to follow. I was able to quickly enable Swiftcalc on my computer. When I am asked to go out and find new space I manage, but I usually have to pay someone a lot of money. Easy to use. If I had to lease space with no experience, I would be overwhelmed.
Graphs are excellent.
Saves hours of manual calculations. Well-organized, clear, easy to follow, not overwhelming, probably even for someone with little or no knowledge of Excel. Word descriptions of each cell are clear. I found it easy to use. It was simple to enter everything and see the differences little changes made between the leasing options.
