The default calculator on your iPhone doesn’t offer the flexibility of adding the calculator to the Widget screen. That’s a real shame since it is one of the most useful apps on your iPhone and one that is used quite frequently.

If you are really missing the utility of the calculator on the iPhone’s widget screen, you can get the Calculator app from International Travel Weather Calculator. The app is free to download but there is a subscription plan and IAPs if you want more.

The Calculator App

The Calculator app is more than just your average calculator. It allows you to do all the usual basic math calculations. But turn it around to the Portrait mode, and it become a scientific calculator allowing to to perform logarithmic functions, equations and other scientific calculations.

The app also features a built-in currency converter. Just select your location to automatically have the appropriate currency activated. Then its just a question of tapping the Converter button at the top left of the screen to view the calculations in the local currency.

The app also lets you view a history of your calculations and also copy the result or equation from the History view. Plus, the app offers drag and drop functionality and full support for the Apple Watch.
