Sleek spreadsheet Document Editor & Viewer
This is tge Software Publisher's description.
Permanent brings the power of columnar databases to the spreadsheet world. You don't have to change anything about how you use spreadsheets. Enter the data any way you want, as much of it as you want, and then ask questions you would've never been able to ask your old spreadsheet. The technology behind Permanent has been proven at the companies with the largest datasets and the toughest and most exacting latency requirements. Now you can use that same technology to run calculations on your spreadsheet.
Permanent is well-designed. The toolbar clearly indicates where you are in the app. The toolbar animations are easy to follow, and let you know what's going on. We have touch tooltips that explain what each button does. We try to design the buttons so that they are self-explanatory. File selection is familiar to those who use iOS. We've put a lot of care into the design.
Permament supports a wide range of spreadsheet formulas. Common spreadsheet operations and spreadsheet functions are supported. You can use math and string operations (+ - % * / ^ and &), formula comparison operations, and area operations (union, range, and intersect). 25 formula functions are supported (view list below or on our website), The function list will grow as the app is updated, soon to include all 300+ spreadsheet functions in common use.
