Apple App Store guidelines to publish your app

Your mobile app is ready to be published on the Apple App Store. We recommend you follow the guidelines laid by Apple to avoid getting rejected.
Most apps get rejected by Apple because of “App Completeness”. In simple words, the final version of your mobile app should include the necessary and required information. This critical information includes the metadata (as per the guidelines) and the functional URLs of the app.
Moreover, make sure you remove all placeholder text, links to empty websites or temporary text. Lastly, your app should be tested thoroughly before you submit it for App Review. There are two categories under app rejection. Have a look:

Metadata Rejection

In most cases, apps are rejected under this category because they are missing information. You can focus on the following points:

Hidden features

Disclose all features that are a part of your app, even if you have not documented it. Also, make sure you don’t include information on features that are not a part of your app.

Screenshots

Add high-resolution screenshots. Apart from being a mandatory requirement from Apple, screenshots are helpful in driving more downloads.

Previews

Create a good quality video to explain how your app works and what it offers. Include a voice-over and content to explain it too.

Category

Select the right category under which your app will be launched. This will not be the criteria for rejection. Apple has the authority to change the category of your app.

App title & Subtitle

You can name your app in 30 characters. You will get another 30 characters to write your Subtitle.

Content

Only include screenshots, previews, and content on your app that is appropriate for 4+ age.

Binary Rejection

Getting your app approved if it is rejected under this category can be a little difficult as compared to Metadata rejection. Apps are rejected under this category because of the following reasons:

Bugs

Make sure your app is bug-free. Apple Review must not be taken as a review platform.

Broken links

Again, there must be no broken links to your app. Conduct thorough testing to find broken links and fix them.

Request permission

Mobile apps that access other apps of the user’s device, must ask for permission to access it. A prompt for the user to take their consent is the solution.

Interface

Besides submitting an app that is high-performance, it must have a seamless interface too. A below-average interface can be the biggest reason for rejection.

App value

You can’t expect that your app will be accepted by the App Store if it offers no value to the end-user. For your app to be approved by Apple, it must offer great value too.

Duplicity

If your app is a replica of any other app that already exists in the app store, there are high chances of binary rejection.

Multiple apps of similar nature

Apps that are built around the same purpose and are submitted by the same developer account are often rejected. You can instead combine multiple apps to publish one that offers a one-window service to the end-user.
