Skewsoft is a micro ISV focusing on Mac and iPhone applications. Our first iPhone app, Sums, will be posted to the App Store soon. Here's a marketing blurb about the app:
Sums is a notebook for numbers. With it, you can record, edit, and keep a running total of the amounts, tallies, scores, and figures that matter to you. Use it to write a budget, track expenses, balance your checkbook, tally game points, log your mileage, or manage any other list of numbers in your life.
Don't waste your time with spreadsheets or other complicated apps. Sums provides a simple, intuitive, paper-like interface that lets you enter, edit, rearrange, and delete figures quickly and easily. All it takes is a few quick taps to get a number out of your head and into your iPhone or iPod touch.
