Successful apps get updated at least once a month including both bug fixes and new feature releases. The frequency of your app updates will depend on the number of feature requests and bug reports from users as well as the resource of your software maintenance team. Every update you make should get approval from Google Play Store or Apple App Store before it becomes available to users. Therefore it’s better to batch several new features and bug fixes in one release than to push frequent small updates. With this approach, your release notes will be more informative and worthy of your users’ attention.
