iOS In-House Apps: What They Are and How to Install Them on iPhone

In-house apps are custom applications developed by organizations for their internal use. These apps are not available on the public App Store and are distributed privately within the organization. This guide will explain what iOS in-house apps are, their benefits, and how to install them on an iPhone.

What Are iOS In-House Apps?


iOS in-house apps are applications developed by companies for use within their own organizations. These apps are typically used to streamline operations, improve communication, and provide employees with tools specific to their roles and the company's needs. Unlike public apps available on the App Store, in-house apps are distributed directly to employees or authorized users.


In-house apps are distributed using Apple's Developer Enterprise Program. This program allows organizations to create and distribute proprietary apps internally without going through the App Store. The apps are signed with an enterprise distribution certificate, ensuring they can be installed on any device authorized by the organization.

Benefits of In-House Apps

1. Customization

In-house apps can be tailored to meet the specific needs of the organization, providing features and functionality that are not available in off-the-shelf solutions.

2. Improved Security

By distributing apps internally, organizations can maintain greater control over the security and privacy of their data. In-house apps can be designed to meet the organization's specific security requirements.

3. Increased Productivity

Custom in-house apps can streamline workflows, automate tasks, and provide employees with the tools they need to perform their jobs more efficiently.

4. Cost Savings

Developing in-house apps can be more cost-effective than purchasing multiple software licenses or subscriptions for third-party applications.

How to Install In-House Apps on iPhone

Installing in-house apps on an iPhone involves a few steps to ensure the app is trusted and can run smoothly. Here’s how to do it:

Step 1: Download the App

First, you need to download the in-house app from the source provided by your organization. This is usually done via a secure link or through the organization's internal distribution system.

Step 2: Trust the Developer

Since the app is not from the App Store, you need to trust the developer before you can run the app. Here’s how:

  1. Open Settings on your iPhone.
  2. Navigate to General > Device Management or Profiles & Device Management.
  3. Under the Enterprise App section, you will see a profile for the developer.
  4. Tap the profile name and then tap Trust [Developer Name].
  5. Confirm that you want to trust the developer.

Step 3: Install the App

After trusting the developer, you can proceed to install the app:

  1. Open the downloaded app file (usually an IPA file) from the download location.
  2. Follow the on-screen instructions to install the app.
  3. Once installed, the app should appear on your home screen.

Step 4: Launch the App

Tap the app icon on your home screen to launch it. Since you have trusted the developer, the app should open without any issues.

Troubleshooting Common Issues

Untrusted Enterprise Developer

If you encounter an "Untrusted Enterprise Developer" message, it means you have not yet trusted the developer. Follow the steps in the "Trust the Developer" section to resolve this issue.

App Installation Fails

If the app fails to install, ensure that your device has sufficient storage space and that you are connected to a stable internet connection. Additionally, verify that the app is compatible with your iOS version.

Expired Certificate

In-house apps are signed with enterprise certificates that have an expiration date. If the certificate expires, the app will no longer run. Contact your organization’s IT department to renew the certificate and redistribute the app.


iOS in-house apps provide organizations with customized solutions to improve productivity, security, and efficiency. By understanding how to install and manage these apps, employees can take full advantage of the tools provided by their organization. If you encounter any issues, follow the troubleshooting steps or contact your IT department for assistance.
