How can I limit my child's time usage on iPad?  He spends too much playing on his iPad. I heard that iKeyMonitor can do it. Is it truth?

There's many apps to limit a child's access through timers etc. eg: give the kid 5 hours to use their iPad and it will be locked behind a password after the period.

Simply discipline your child so that he/she only receives are certain amount of time per day.

don't think so its possible

It Is If they don't have access to their device.
