Comment (by igt0):

 I have been thinking about this problem for some time and I propose two
 things:

 1. Add in the onboarding a link to the wiki about how to validate the APK.

 2. Add a button in the TBA menu called "Validate App". When the user
 clicks on it, TBA fetchs a json from the onion service with information
 about what is the current version and signin certificate and checks if the
 current certificate is the same of the installed app. We also should tech
 the user that this approach doesn't work if the app is tampered.

 sysrqb, GeKo: any thoughts?
