# Publish to Google Play Store Success on Google Play starts with quality. The best apps and games have higher ratings, more installs, and more engagement. We recommend visiting the [Play Store Developer Policy Center](https://play.google.com/about/developer-content-policy/#!?modal_active=none) before you submit your app to the Play Store. Publishing to the Google Play Store requires a Google Play Developer Account (approximately $25 USD one-time fee). Don't have an account? [Sign up here](https://play.google.com/apps/publish/signup/). ## AAB vs APK When you [download](/settings/manage-your-projects/download/download.md) an app from Thunkable you receive an email with an **APK file** that you download directly to your Android device. When you publish an Android app you receive an email with an **AAB file** for you to upload to the Google Play Store. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
