That depends where you choose to make your app available.
We will automatically publish your app to Aptoide and send you your APK file.
Anyone with an Android phone can download your app from Aptoide or download your app if you send them the APK file.
With your APK file you can also upload your app to other App Stores, for example Google Play Store.
If someone does not have an Android device, they can still access your mobile website. The mobile website is sent to you as soon as you publish.
