About PowerOne

PowerOne® is a different kind of calculator that makes fast work of calculations you repeat regularly (plus a full-featured standard and RPN calculator for those you don't).

PowerOne does this in three ways. First, it makes it quick and easy to get results. Calculation templates are laid out like mini-spreadsheets. Input what you know and PowerOne will calculate what you don't. PowerOne runs perfectly as an iOS app and in your favorite mobile or desktop web browser.

Second, creating templates is simple. While most of us can read and write sentences, far fewer have the same comfort level with numbers. That is because we often talk about math in abstract terms — x or y, A3 or C4 — concepts that most of us don't understand. PowerOne, on the other hand, allows you to describe numbers using phrases, which turns equations into readable sentences. While you can create your own, we also provide hundreds of pre-created templates that you can use and/or customize.

Finally, sharing templates is as simple as sending someone the web address.

Award-winning PowerOne was invented by Infinity Softworks, Inc. (now Crafty Weasel, LLC) and has been distributed to over 20 million customers since 1997. Partners have included DEWALT, GE Security, Samsung, Sony, National Association of Realtors, ETS and the College Board, among others.

This completely re-designed and re-thought version of PowerOne, which became available in early 2018, is the culmination of over 20 years of thinking on our relationship with numbers. We hope you enjoy the service!


Elia Freedman (linkedin, twitter, mastodon, blog) has been developing number-oriented software products for over two decades. Elia discovered a love for numbers as a pre-teen, creating dice and card-based baseball games in an attempt to simulate real-life. This love carried to his first computer, an Apple IIc, and into college.

When the Pilot 1000 launched in 1996, Elia saw an opportunity to develop finance and calculator software, forming Infinity Softworks, Inc. Elia saw an opportunity to present numbers in a new way, showing all the data on the screen at once rather than in a small view window. He partnered with Rick Huebner, who had developed a powerful calculation engine and a Palm OS math library de facto standard. His Parens and MathPad apps were scientific must-haves. Combined they built this hybrid calculator-spreadsheet idea into the best-selling PowerOne calculator product line when Rick joined the company in 2001. Over the years and with the help of others, Elia and Rick developed versions for iOS, Android, Windows, BlackBerry, Palm, and Windows Mobile, distributing over 20 million software calculators.

In 2022 after Rick retired, Elia closed Infinity Softworks, merging PowerOne into his new company, Crafty Weasel, LLC.
