Turn the iPhone into a Scientific Calculator by Rotating Calculator App
Need to use a scientific calculator on the iPhone? Instead of downloading a new app, just launch the existing Calculator app and then rotate the iPhone so that the screen orientation is horizontal. This instantly transforms the calculator app into a scientific calculator, no visit to the App Store is required.
This will work on the iPod touch as well, and has been around in iOS for quite some time now but apparently we haven’t posted the tip before. Thanks for sending this in Jared!
