Over the years I've received many requests for mobile app versions of the popular calculators on this website. However, due to the high cost of native app development ($4,000 to $10,000 per app), apps were simply out of the question.
Thankfully, recent developments in hybrid app technology have now made mobile app development much more affordable ($150 - $250 per app).
So in December of 2015, I partnered with a mobile app developer to help me convert the most popular online calculators into mobile apps that can be downloaded and installed on your mobile device.
We are building calculator apps from most popular/requested to least popular/requested. So be sure to check this page often to see if your favorite has been published to the app stores.
If your favorite is not currently available, please contact me and let me know which online calculator you would like to have converted into a mobile app.
Below is a list of the Android and IOS apps currently available on iTunes and Google Play.
Tap the app logo or link to go to the online version of the calculator, which is followed by links to the app store version associated with your device.
This calculator app will calculate the sales taxes on the price of a product or service given a sales tax percentage (price plus tax), and if you want, will also tell you the number of hours you will need to allocate to working in order to pay for those taxes.
Plus, if the price you entered already includes sales taxes, the sale tax calculator will calculate what portion of the price is for the product or service and what portion is for sales taxes (in reverse, or backwards from total).
The app also includes a route map, turn-by-turn directions, a fuel-cost estimator, a speed comparison chart showing your drive time and ETA at slower and faster average speeds, and a printer-friendly trip report.
