Mostly good

I like this app. It makes it easier to get my kids off their iPads into the great outdoors. Easy to use, super effective in monitoring screen time and limiting access to child appropriate apps only.
My only beef is that it sometimes takes a long time to switch modes...like 10-15 mins. This is particularly annoying for my kids when they are in lockdown mode and we want to switch to child mode. Still worth it though.
