The iPhone routinely offers advice on how long it will take to drive wherever iOS thinks you're going. Apple Maps makes an educated guess based on Location Services data. What you might not know is that iOS stores a list of Significant Locations on your device to make this happen. iOS makes it possible to see your Significant Locations on a list or even on a map.
If you owned an an early generation iPhone (or any camera phone or digital camera) before it was equipped with GPS, chances are you have photos in your camera roll that have no location information. iPhones now geotag your photos automatically (unless you have turned the feature off), which helps with categorizing them and allows them to import into your "Places" album. You can, however, add locations to your "dumb" photos using Apple's Photos app on a Mac. Here's how to do it:
It may be one of the oldest app functions in existence, but many iPhone users don't take advantage of the Reminder app as often as they should. That’s a shame, because the iPhone’s reminder system has received so many updates over the years that it arguably rivals any third-party apps specifically designed for reminder purposes.
The app is so feature rich, in fact, that to this day users are discovering wonderful new abilities that allow it to remind you of tasks in very specific locations.
iPhones have been tracking your movement for some time now (if you have Location Services turned on). You can see all the places you have visited recently, including duration of your stay. You can view this in list form or see it on a map. Head to Settings -> Privacy -> Location Services -> System Services -> Frequent Locations. Here you can toggle Frequent Locations on/off and see a list of locations. Click on a location to see it on a map with greater detail, including how many visits you've made and for what duration.
It might seem like GPS coordinates can be added to a contact on the iPhone, after all when tapping a pin in the Maps app iOS provides the option. The reality is that Contacts only supports storing addresses, not latitude and longitude coordinates. The location that's actually stored in the Contacts app will not be accurate unless the GPS coordinates can be associated with an address.
