+Since SupeApp/Supe.me/Supe.io has closed so I'm disclosing this publicly.
+
+SupeApp was a Social Networking app like Snapchat where users (mainly well-known VIP/Models) could post public/private media for free or by paid subscription.  
+To convince free users to buy subscriptions, paid media were displayed blurred and with a "Pay now" dialog on top.  
+The blurring effect was done client-side so I realized a PoC python client to call the API directly and store the clear media.
