What technologies does SoloLearn use for its apps and website?
Does anyone know what technologies Sololearn uses? What is use for the website and for their apps (Java?Swift?C#Xamarin?jQuery mobile?). I'm especially interested in what is used with regards to storing user data and progress (jquery/node.js etc)
I'd really like to start making a learning platform similar to Sololearn and Duolingo :)
