6. Notify you about your friends' location: Apple's free Find My Friends app can be super useful at times, such as when you're meeting up with a friend. You can even use the app to automatically tell your friend when you're heading out — or be notified when your friend is arriving someplace — all thanks to geofences.
Just launch the Find My Friends app, select the friend you want to be notified about and tap the More... button in the toolbar. At the bottom of the contact card, choose either Notify Me or Notify [your friend's name]. You'll be prompted to choose whether the notification will show up when you arrive at or leave a place, as well as specifying the location (and even how big a radius from that location will trigger the notification). If you choose to notify your friend about your location, you can also send a message immediately.
7. Ask Siri to notify you about your friends' location: If setting up those geofences is a little too cumbersome, you can ask Siri to handle it for you. Just trigger the virtual assistant and say, for example, "Notify me when John leaves his current location."
8. Geofencing in Reminders: Not only can you can set geofences on people, you can also place them on locations. Using the Reminders app, you can have a notification sent to you when you're arriving at or leaving a location. Just create a reminder, tap the i' button next to it, and choose "Remind me at a location." Under the Location sub-menu, search for a contact, place name, or specific address; as with Find My Friends, you can even specify the size of the radius around the location, just in case you want to be reminded to get cookies when you're even remotely near the supermarket.
Master your photos
9. Save your favorite Burst Mode images (iPhone 5s): The iPhone 5s's Burst Mode is an excellent way to ensure that you capture fast-moving action, but you also don't want to take up lots of space with photo duplicates. After you've captured an image in Burst Mode by pressing and holding down the shutter button for a few seconds, you can tap the Camera Roll to view your images.
Your burst appears as a single photo in the album, represented by what iOS 7 thinks is the best photo of the bunch. You can go back and look through the full burst collection, however, by tapping the Favorites button; select the photo (or photos) you'd like to showcase by tapping on them and pressing Done. From there, you can choose to keep the entire burst for future perusal, or delete all the images you chose not to select.
