API Mashup creator for your WiFi displays

CALE is a screen administrator where you can mix the content of different APIs and control the output.

You can use it on any WiFi display like your tablet, mobile, or ultimately in a WiFi E-Paper screen that is every hour fetching new content at minimum consumption.
