You sort of have one but not really. You can launch it from the Android Proton Drive app. Granted it then launches it into a web browser, but GrapheneOS/Vanadium seems to handle it well. Would also prefer an app, or allow me to use Standard Notes as the client and sync with my Proton account.

I use a FUTO voice and Helio keyboard combo by just calling FUTO from Helio when I want to dictate. Works great for me. I tried the FUTO keyboard and it works well enough but not quite as well as Helio for me. Still contribute money, though, because I like where they are headed.

If they treat it the way they do with Simplelogin, then you can choose to keep your accounts separate. Just the option to log in via your Proton account will be a future option if they end up including standard notes as a premium feature.

…and volatile ammo. I’m in.
