Simple: Build the binary you upload to the App Store with the code from the repo ;-p OSS ist the only solution and finally also governments seem to accept that. I don't trust most OSes, that includes iOS & Android. My phone is being considered an unsafe device and I don't trust it with the data I'd like to query with an app like this. I don't even want to have to block the app's access to internet etc. but simply be able to trust it as an OSS app that runs on my linux for tasks like this.
