Best way to distribute M5 Core app to customers

[Leo05]

Hi,

What is for you the best way to distribute an app I developped to my customers ?

• customers are not technicians or makers, it must be simple to burn it (no IDE usage)
• the app must be closed source and protected from copy and reverse eng (encrypted bin)
• users must be able to update the application, by downloading a new version and burning it onto the card
