The Tinker app on the iPad has a problem. When children use the Tinker app, the response is slow after touch. Touch an empty project and wait. It is also slow when saving a project.
Apologies for the delay in responding. Are you still having the issue? Please send a note to support@tynker.com - we’ll need know the version of the app you are using, the language and location. I am assuming your Internet connectivity is good throughout the day.
