What problem does it solve? Releasing an Android app update to all users at once risks widespread crashes and negative reviews. This Skill guides gradual, percentage-based rollouts on Google Play so issues are caught early with limited user impact. ## Core Features & Use Cases - Staged Rollout Control: Start releases at a fraction of users, increase percentages, halt, resume, or complete rollouts using gplay CLI commands. - Monitoring & Decision Matrix: Check rollout status, filter recent and 1-star reviews, and apply crash-rate thresholds to decide whether to continue or halt. - Rollback & Automation: Handle hotfix releases, promote previous versions, and automate daily rollout increases via CI/CD workflows. - Use Case: You release version 2.0 to 10% of production users on day one, monitor crash rates and reviews for 24 hours, then progressively increase to 100% over a week using the conservative rollout strategy. ## Quick Start Ask the assistant to start a staged rollout of your app bundle to 10% of production users on Google Play and show how to monitor and increase it.
