Great catch by Tom Klaver — use the new "Guided Access" accessibility option in iOS 6 to help you focus.
Notifications won't show up when it's activated, double clicking the home button won't open the multitasking tray and notification centre isn't accessible.
Here's how to turn it on:
Try this:
- Turn on Guided Access in Settings > General > Accessibility.
- Switch to your book app.
- Triple-click the Home button to invoke Guided Access.
- Tap ‘Done’.
Switching to your distraction apps now takes 3 clicks on the Home button, filling in a passcode, a tap on the ‘End’ button and a click on the Home button. Enough of a hassle to stay focused, I believe.
I will be using this a lot. Do Not Disturb is great — but it only stops notifications when your device is locked. This works when you're actively using it.
