Desktop guide
Linux · about 15 minutes to install, then at least 18 Bitcoin blocks, typically around three hours or more, but it varies (mostly waiting). Install PCOC Hike, make a key, make a PCOC, and check it. With screenshots.
Phone guide
Android · about 20 minutes once you already have a PCOC from the desktop. Bring the PCOC into the app and sign in to this site. Screenshots are coming.
Rebuild from source: Flatpak from tag desktop-v0.1.8 (build-bundle.sh); Android app 3.5.50 from commit 5a1d4f5f3 (./gradlew :app:assembleAospDebug). The Flatpak rebuilds from that tag. The APK rebuilds from that commit. Neither build is bit-reproducible. The published APK is debug-signed. That commit is on primal-pcoc main (#54, merged). Tag android-v3.5.50.
