Sales Tax Calculator App Icon

About The Calculator Apps

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 has 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.
