If you’ve ever wanted a scientific calculator app on iPhone, don’t worry – your iPhone already has one built in. Apple’s Calculator app includes a hidden science mode. Here’s how to use it.
First, open the “Calculator” app. If you can’t find it, swipe down with one finger in the center of the screen to bring up a search bar. Type “calc” and select the “Calculator” app icon when it appears.
Once Calculator opens, you will likely see a screen like this. It is a simple interface with a grid of numbers and basic mathematical operators. Hardly scientific!
To enter scientific calculator mode, rotate your iPhone 90 degrees until it is in landscape orientation. The Calculator app will automatically adjust to fit the wide screen orientation and the new scientific calculator buttons will be added to the display.
If your calculator doesn’t go into scientific mode when you rotate your iPhone, chances are you have orientation lock enabled. To disable it, open Control Center and tap the orientation lock icon until it is no longer highlighted.
Once orientation lock is off, rotate your iPhone again while running the Calculator app and you’ll see Scientific Mode in all its widescreen glory. A brave new world of more complex math has opened up for you. Have fun with the exponents!
