Chatster is a fun and safe chat app for young children. Kids can send messages to their friends and family, without having to be able to read or write! Even the younger kids from ages 2 to 7 can send messages this way.
Chatster is available for iPad and iPhone devices. It has notification functionality, so you get alerted if you receive a new message. There is a limited but well chosen set of emojis available. The interface is quite easy to understand, your kids wont have any problems navigating through the application.
Parents can create accounts for themselves, and for their children (register here: http://www.chatster.nl). You can handle friend requests through the parent accounts only.
