One detail that’s been flying under the radar is Spotlight’s new ability to solve simple math problems directly from the Spotlight interface. It’s like having a calculator app that’s readily accessible with just a simple swipe from the Home screen.
It’s the little features like this that will convince me and others to use Spotlight search in iOS 9 more regularly. In versions previous to iOS 9, Spotlight was more of a forgotten afterthought.
Also you can use spotlight to quickly change Dollar to Euro or vice versa and the rest of coins..
So what do you think ?
