To achieve the requirement we need to create two custom lists i.e. "All Apps" and "User App".
The "All Apps" list will have the columns shown below:

The "User Apps" list will have the columns shown below:

- Title: column contains the Users Name
- Application: column will be the lookup column from "All Apps" with multiple option selection.
In this article I am not going to explain the process of adding users with applications. For your reference I am just adding the user manually and the final list will look as shown below.
The "All Apps" list after filling data will look like:

The "User Apps" will look like below:

I have created a user control which contains the UI for the Application bar.
For User: TSTMOS30

For User: TSTMOS36

You can find the code attached with this article.
Hope it will support you while creating an Application toolbar with personalization.
