Got this from @Salah_Baker
Interesting. Essentially “Clockit” boxes that also maintain sync using Wifi radio signals. That same Wifi signal can be picked up and read by its companion iOS app, meaning iPhones and iPads can be visual slates, as well as control the boxes. Cool if it works. I have to say, the instructions to operate Denecke slates are very arcane. Maybe this will eat their lunch…..
