Show HN: I made a tool for creating Web Apps with spreadsheet logic

Background: There are many great spreadsheets. Spreadsheets for creating quotes, for tracking orders, tracking kids learning to swim. But staff would rather use a good user interface, with buttons etc, than a spreadsheet when doing work day to day.

Examples: http://sheet.cellmaster.com.au/examples Slow - complex app: http://sheet.cellmaster.com.au/carbonoffset/app

How: It adds GUI formulas and event handling formulas to a standard spreadsheet.

Looking for: Early adopters and use cases.

Stack: Nodejs - JS/livescript - redis https://github.com/audreyt/ethercalc - Built using Dan Bricklin's (inventor of the spreadsheet) open source spreadsheet

Warning: It is slow with large volumes of data/formulas. It needs work.

Tag line: Web apps as simple as spreadsheets
