About PowerOne calculator
Download hundreds of calculations or create your own with PowerOne® calculator.
• Several-time Apple staff pick + Best of 2010
• "The crème de la crème of calculators" – AppAdvice
• "Incredibly powerful tool for calculations of all kinds." – Smokin' Apps
• "You need this calculator. It's miles better than the competition." – Robert Burns
• "… sets the benchmark for other calculators to reach." – Fred Swan
• "Not sure how I could do my job without PowerOne." – Arvid Martin
• "A legend. The best … calculator app I have ever seen." – Worldwide Tech
• "… PowerOne shines." – The Mac Observer
BENEFITS/FEATURES
• Quick and accurate. Templates act similar to locked-down, mini-spreadsheets that increase accuracy and speed for repetitive calculations. Enter the data you know. PowerOne will calculate the rest.
• For those one-off calculation needs, PowerOne provides a powerful standard and RPN calculator. Over a hundred functions to help with virtually anything: basic math, powers, logs, trigonometry, probability, programmer’s math, fractions, and Imperial and metric units.
• Get up and running fast with hundreds of pre-created templates in PowerOne's extensive library. Covers everything: finance, conversions, real estate, business, investing, construction, engineering, health, fitness, and more.
• While some calculations are common, there are millions more specific to you or your business. With PowerOne, it is easy to create powerful templates of your own using our intuitive language. You, your team, and your customers can perform their own calculations without ever having to think about the math.
• Access PowerOne everywhere. Whether on the go with your iPhone or iPad, on your M1 Mac, or at your desk on the web, PowerOne makes sure your critical calculations are available at your fingertips, offline or on.
• Keep everyone on the same page. Share your templates with your team and customers, ensuring that everyone is performing the same error-free calculations every single time.
• Highly customizable. Go beyond templates with expanded calculator functions and themes! Match your mood and make it the product you want to use every day.

Dec 6, 2018
- Syncing for all! This release adds syncing and access to the web version for everyone — even those of you who prefer to remain anonymous — available at https://power.one!
- New template creation tutorial: Steps through template basics and various settings. And of course, it can be skipped if you already know what you’re doing.
- Template creation: Includes a completely new editor, significantly improving the template creation process on iOS.
- Complete rethink of sync plumbing: We’ve made it more stable long-term. Hopefully you won't notice any differences!
- Improvements to account creation: Easily move between a named and anonymous account, access to web version with an anonymous account, change your email and/or password, and more.
- Subscriptions: While most of PowerOne is free, choose between monthly and annual subscriptions to access premium templates, template creation, advanced sharing, and extra themes. Please support PowerOne development. Subscribe today!
- Web improvements to match iOS changes.
- iOS 12.1 compatibility for the new iPads Pro.
Bug Fixes:
- Fixed a bug where subtract and power would not automatically continue calculations in the calculator (standard input mode).
- Fixed a bug where using PowerOne with a physical keyboard could cause the keyboard to stop responding to input after the first modified row.
- Other fixes and stability improvements.
Please send any feature requests, found bugs, or general thoughts to help@power.one. We'd love to hear from you!

The big news this release is Team accounts! Contact us at help@power.one if you are interested in sharing templates with your team.
In addition, we added some treats specifically for those of you who create your own calculation templates:
- Added a setting to treat all variables as case sensitive. (V = v + a has three variables, not two.)
- Added a setting to assume equations have math left of the equals sign. (A+B=C+D has four variables, not three.)
Now... Rick and I are ready to focus on the feedback we received from all of you! So excited!

5.1.2

- Selecting done button in the calculator when viewing history now shows keyboard, tap again to dismiss calculator completely
- Option to add left and right parenthesis separately or 000 buttons to your custom calculator keyboards; all three are also available in the math list
- Fixed a bug where modulo function mod() would return an error if the result of the division caused lots of decimal places
- Other bug fixes and smaller improvements

5.1.1
Mar 14, 2018
All that work, all that time, all that testing and... we missed something. Of course!
In version 5.1.1 we fixed an issue with the dismiss keyboard button showing in the custom keyboard options. In addition instead of forcing its location on your custom keyboards, based on a customer suggestion, we instead made it an option. You can show it, remove it, or move it wherever you see fit.
We also fixed a few smaller issues while we were at it.
---
If you are just catching up, here are updates from our previous release (version 5.1):
The feedback has been tremendous! Thanks to all who emailed me what you liked and what could use improvement. With this major release we have...
- Percent change is back! You can once again perform percent change math in the calculator with addition (100 + 25%) and subtraction (100 - 25%) using standard input mode.
- We've added hundreds of templates to the library. There are now over 300 for finance, business, investing, construction, conversions, math, science, engineering and more.
- Amortization tables (and other read-only tables) look so much better, even better than version 4.
- Major change to the calculator: focus mode. By default the history, memory, RPN stack, and current template are hidden with a much cleaner look. History is accessible with a single button (dismiss keyboard) and there is now a setting (Always Show History) to display them all the time.
- New built-in units for your custom templates. We've added miles and kilometers to a new length option and gallons (US and UK) and liters to a new volume option. (These add to the length, area, volume, duration, mass, and temperature options previously provided.)
- Calculator now includes a reciprocal button. (Don't know how we missed that one.)
- Other bug fixes and smaller improvements.
Please, tell me what you like and what you don't. It's how PowerOne keeps getting better.

We are adding lots of templates to the library every day now. We thank all of you for walking through the importer and telling us what's missing.
We also did some bug fixing, with the biggest issue -- the calculator sometimes appears incorrectly if the current template is changed on a different device -- resolved. There are smaller fixes as well.
Please tell us if you run into anything, big or small, even if you are not certain its a bug! help@power.one.
