Shipaton 2025 - Day 18 - Internal Testing Release

What I Built Today

Today was about getting a real, signed build onto real devices safely.

✔️ Prepared the first signed release build.
✔️ Set up Google Play Console → Internal Testing with clear release notes.
✔️ Invited a small tester group.

🎯 Result: the app is now installable via Internal Testing, so I can start collecting real-world feedback before the public release.

Why Internal Testing Matters

Your first signed build is more than a checkbox - it’s the moment the app leaves theory and meets reality.

Real signals, low risk. Internal tracks let you ship fast to trusted testers without exposing rough edges to the public.
Production-like behavior. A signed, optimized build surfaces issues you won’t see in debug: missing resources, network quirks, startup cold paths.
Tighter feedback loops. Release notes + a checklist turn vague “it feels off” comments into actionable fixes you can knock out quickly.
Store pipeline rehearsal. Uploading artifacts, writing notes, and rolling out versions now means fewer surprises on launch day.

Conclusion

The app now ships through the Internal Testing track: install → test → learn → iterate. This unlocks higher-quality feedback under real conditions while keeping risk contained. It also hardens the release pipeline: versioning is clean, the build is optimized, and the tester experience is intentional. Small step, big leverage toward a smooth public launch.
