Troubleshooting: Screen will not turn off when app is running?
Kiosk Pro automatically disables the iPad's Auto-Lock because it's our experience that visitors simply don't approach kiosks that appear to be turned off. In addition, in most kiosk applications, devices are placed into enclosures that limit access to the Home and/or power buttons, which are necessary to wake an iPad from a sleep state.
In our Plus and Enterprise versions, we have included a setting to re-enable Auto-Lock on the device, which may be appropriate for other use cases (like a sales presentation or trade show where the device is not used in an enclosure).
