You can change many of the settings in iasku. To change the settings press the cog in the top right while in Admin mode:
Sounds and Alerts: turns on a sound when you make a selection in the app. In this way you and your child will get audible feedback when an option is selected.
Application appearance: shows or hides the "page buttons". These appear at each side of the screen so that you can scroll using a finger press rather than a swipe.
Restore purchased content: this option will allow you to restore all the purchased categories and cards.
Send feedback / request a feature: this option allows you to send an email to the creators of iasku to suggest new features, categories, etc.
