ISO 27001 and application security

(Hello, my question is the following: I use ISO 27001 to propose a security scheme in a mobile application ... or which standard you would recommend for the security scheme (mobile app).)

Answer: ISO 27001 can provide you a general security scheme, but for more detailed guidance on mobile application we recommend you to take a look at ISO 27034, an ISO 27001 supporting standard covering specifically application security. You can have a preview of this standard at this link: https://www.iso.org/standard/44378.html

You can also consider the OWASP project to built a robust application.
