Guided access is a way for you to lock down your iPad so that:
The iPad doesn't go to sleep, and...
Your patients can't leave the Finger-Ink app
We strongly suggest enabling guided access as it's designed to be used for a scenario just like this – kiosk mode.
Guided access is an iPad setting (outside of Finger-Ink) and while we can detect whether or not it's enabled and running, you have to go to the Settings app to enable it.
We'll show you a little indicator if guided access isn't running, like this:
If you tap learn more, we'll tell you a bit more about what guided access does as well as link you to the Settings App to enable it.
Enabling guided access
Enable Guided Access through Settings > General > Accessibility > Guided Access. It's best to set a passcode as well.
Launch the app you want to lock the iPad down to (i.e. Finger-Ink).
Triple-click the home button (the hardware button on the front of the iPad).
When the guided access menu comes up, tap the options button in the bottom left hand corner of the screen and turn on the Sleep/Wake Button.
Hit the start button in the top right hand corner of the screen.
