Ummm… you go and ask them to hop off and explain why. We always recommend giving kids prior warning about what time you’re needing them to get off, so they can finish up what they’re doing. Ten to fifteen minutes warning is a good amount (which is why ScreenCoach will warn the kids when their time is running out). This helps to minimize those pesky tech tantrums. Note that ScreenCoach is not designed to replace parents, but to help them (and their kids!).
If there are regular times that you don't want kids to be using their screen time that's when you can set up the modes and the access times. For example you may not want them to be using any screens around dinner time or before school.
In the near future, you will be able to block kids for a period of time even if they have access time and available time to use.
