math3g.com --> Math applications to touch...
Inspired by the iOS touch interface in early 2008, Nolan Piper began working with ideas to make math more engaging and visual. Ten apps were developed and launched, and Percent Calculator was an early favorite. With customer feedback and many early updates, it gained function and refinement to become a powerful business/sales calculator.
Featuring one-touch percent keys, one-touch programming, Sell-Cost-Profit-Margin (enter any 2), percent change and more, this business app facilitates quick calculations and effective analysis. It is ideal for anyone in sales.
Touch the display to see a list of recent calculations.
1) 3-line main display, visible memory, and bar-graphed results.
2) A% allows positive or negative settings for mark-ups / discounts.
3) Tax supports split taxes and minus tax (to extract the original and tax from a total).
4) Sell-Cost-Profit-Margin includes margin bump buttons and scaling factors for results.
Get more with every calculation.
Available on the iTunes App Store.
2008 - 2016 Highlights
The Percent Calculator has been refreshed, and work on other apps is starting. There is much work to be done, but it will be fun. Thank you for your interest in my apps.
