Image 2 Bits teaches binary encoding using black and white images.
Coded images are shared with classmates wirelessly even if you do not have access to a network, and after decoding images, children can like them and then keep them in their picture gallery. Likes appear on the creators screen while they are decoding others images.
Basic help screens explain how everything in our digital world depends on binary encoding, and interactively demonstrates one method of decoding.
Bonus screens demonstrate addition and multiplication of binary numbers.
If you share iPads in your class, there is a restart button to enable a second child to create and share their own picture.
Troubleshooting: To enable sharing, Bluetooth and Wi-Fi should be turned on, but, for the unlikely case that an iPad will not talk to its peers, there are a few coded images built in.
Privacy: names, titles and images are transmitted to neighbouring iPads and may be intercepted by other network users. Quit the app to erase all stored information.
