If you’ve never heard of guided access and ever have the need to pass your phone around (to share a photo in a small group, a phone number, etc…), then you’re missing out. Guided Access is built in to iOS and might as well be called Phone Lockdown – it lets you lock the user into a specific app, disabling any control you choose (in fact, you can disable all controls and buttons) ensuring that when your phone gets back to you, no one has stolen a glance at your email or done that tempting slide over to see other photos. You simply turn it on and set a passcode. Then anytime you want to freeze the screen, triple-tap the home button, set whatever options you like (disable controls, set a time limit, etc…) and hit “Start”. No more snooping!
