Apps are an important part of any tablet, and being able to access as many as possible is always a bonus. The nabi 2S has access to the Treasure Box, which is a curated app store intended for children, but parents can also install the Amazon Appstore if they wish, giving access to a far greater range of apps.
The Amazon Appstore can only be installed in Mommy/Daddy Mode, and the tablet is set up to install it quite easily, from the Fan-A-Tech app, in which you simply select “Get the Amazon Appstore.” Once downloaded, the Appstore can be moved to the Mommy/Daddy Mode home screen. In Mommy/Daddy Mode you can also disable in-app purchasing in the Appstore.
Also in Mommy/Daddy Mode, you can choose which apps a child can have access to in regular nabi Mode, enabling or disabling them as appropriate, so you can ensure that children don’t use apps that you don’t consider to be appropriate.
