Tangentially, I see the application is native (i.e. not using Xamarin like Bitwarden), you should definitely point this out if you ever make some technical post about Proton Pass, I'm sure HN folks will be interested to hear about it.
Another thing, the client is not only open source but also free software, I think you should definitely point this out as well. I believe this is an important distinction for quite a lot of Proton users. I wonder however if this is OK to do for the iOS client, AFAIK GPL code could not be published on the app store without breaking the license [0].
Last but not least, I noticed that the issues tab does not appear on the Android repo but does on the iOS one, surely this is not intened?

We have now started to use separate organizations for each product at Proton, e.g. the Proton VPN apps are on https://github.com/ProtonVPN and the Proton Drive apps are on https://github.com/ProtonDriveApps.
